Relying on traditional tools and manual processes for compliance in these environments increases the risk of breaches, fines, and delays. To ensure long-term success, organizations need strategies that simplify compliance while delivering strong, consistent security. ### Question: What Is Multi-Cloud Compliance? ### Answer: Multi-cloud compliance is a complex process of adhering to laws and industry mandates concerning [data security](/zpedia/what-is-data-security) and privacy in the cloud. It involves working across platforms to ensure consistent visibility and control over how data is stored, accessed, and shared. Compliance requirements vary widely by region and industry with regard to data handling, data residency, encryption standards, and more. Cloud providers (CSPs) like AWS, Microsoft Azure, and Google Cloud each add to this with their own management tools, configurations, and security policies. Thus, the more clouds an organization uses, the more difficult it becomes to stay fully compliant. To overcome this, organizations need a way to make configuring, maintaining, and attesting compliance easier and faster. ### Question: Why Simplifying Multi-Cloud Compliance Matters ### Answer: Failing to meet compliance standards can have major consequences in these key areas: - **Financial penalties:** Regulations like HIPAA and PCI DSS impose steep fines for violations. For example, HIPAA breaches can cost up to US$71,162 per record, and PCI DSS noncompliance can cost up to $100,000 per month (as of 2025). These penalties alone make compliance a top priority. - **Lost revenue and trust:** Data breaches, failed audits, or negative press can erode customer trust and weaken business relationships. Many companies find it difficult to restore their reputation, leading to lost revenue and reduced growth opportunities. - **Operational disruption:** Noncompliance can force organizations to pause their operations while they address violations or rework systems. This, in turn, can delay product launches, disrupt workflows, and create other ripple effects throughout the organization. By automating monitoring, improving visibility, and addressing risks proactively, organizations can reduce the likelihood of violations. Investing in compliance upfront doesn’t just reduce penalties—it supports the ability to grow without interruptions. ### Question: Multi-Cloud Compliance Challenges ### Answer: What is it, specifically, that makes multi-cloud regulatory compliance so difficult? Let's take a closer look at the major challenges: **Shared Responsibility Models** Most CSPs follow a [shared responsibility model](/resources/security-terms-glossary/what-is-shared-responsibility-model). The CSP handles certain security elements (like protecting physical servers), while the customer is responsible for securing workloads, user access, and configurations. Any confusion about who is responsible for what can lead to compliance issues. For example, a CSP might not notice a misconfigured database, but it still leaves the customer exposed to risks. **Lack of Unified Tools and Visibility** Each CSP offers its own compliance tools, but they often can’t integrate with other platforms. As a result, it can be difficult for customers to get a full view of their compliance across all cloud platforms. Without centralized monitoring tools, they will struggle to detect violations, track permissions, or manage data movement efficiently. **Shadow IT and Lack of Control** In multi-cloud environments, IT teams often lack visibility into unsanctioned tools that may violate compliance. For example, sensitive data could be stored in locations or processed by tools that don’t meet GDPR or HIPAA requirements. Without proper oversight, [shadow IT](/resources/security-terms-glossary/what-is-shadow-it) expands the attack surface and undermines efforts to centralize control over compliance. **Constantly Changing Resources** Cloud resources constantly scale up or down to meet customers' evolving needs. This makes traditional compliance methods, like manual configuration reviews or static enforcement, ineffective because of how quickly they can become irrelevant. When controls can’t keep up, they can leave critical assets unprotected. **Wider Attack Surfaces and Data Sprawl** On top of the operational challenges, multi-cloud environments introduce a larger attack surface. Data is often stored in multiple locations and regions, increasing risk. For example, regulations like GDPR require region-specific handling of data, but tracking compliance for data across multiple jurisdictions can be highly complex without advanced tools. **Auditing Complexity and Overlap** In a multi-cloud setup, compliance audits require the gathering of evidence from multiple platforms. Compared to a single cloud, this increases the time and resources needed, especially when compliance frameworks overlap or conflict. Companies often find it takes months to prepare for audits—time they could be using to improve other aspects of the business instead. **Identity and Access Management (IAM) Failures** Access management across multi-cloud environments can be challenging when each CSP has its own IAM framework. Roles can vary widely between platforms. For instance, a user with admin access in one cloud may need wholly different permissions in another. Without centralized tools, it can be difficult to avoid [overprivileged and unauthorized access](/blogs/product-insights/how-dspm-helps-prevent-data-exposure-overprivileged-access), leading to compliance issues. **Evolving AI Compliance Norms** AI systems may process large amounts of sensitive data. However, AI regulations are still evolving, and they vary widely worldwide. Without proper oversight, organizations risk exposing data, introducing algorithmic bias, or failing audits as AI models interact with multi-cloud resources. This can get complicated quickly if models trained in one jurisdiction are deployed or accessed in another where different compliance mandates apply. ### Question: Why Traditional Strategies Don’t Work ### Answer: Traditional compliance programs struggle to keep up with these challenges in modern cloud systems. They tend to focus on manual reviews, basic security controls, and annual audits. Compliance teams map out all resources, match them to regulations, and confirm controls are in place. As point-in-time assessments, they are functional for static environments, but less suited to the rate of change in the cloud. Here are a few of the ways traditional strategies fall short: - **Time-intensive processes:** Manual configuration monitoring across multiple CSPs is simply not practical when environments change constantly. - **Short shelf life:** Traditional compliance reviews create "snapshots" that rapidly become outdated in dynamic cloud settings, leading to blind spots. - **Knowledge gaps:** Compliance regulations can evolve rapidly. Without up-to-date knowledge and expertise, organizations will struggle to keep up with changes. - **AI complexity:** Traditional programs lack the visibility and scale to effectively identify, benchmark, analyze, or remediate AI data breach risks. ### Question: Strategies to Simplify Multi-Cloud Compliance ### Answer: **1. Create Clear Security Policies and Improve Visibility** Start by defining clear security rules that follow legal and industry standards. Translate these rules into practical actions that guide your users and IT. Use tools that simplify compliance monitoring across all cloud systems to ensure no blind spots are overlooked. **2. Automate Compliance Checks** Automated tools can analyze systems for risks, noncompliance, or misconfigurations in real time. By finding and fixing issues without relying on manual review, you'll save time and effort while reducing your exposure to violations and breaches. **3. Focus on High-Risk Areas** Some areas of your cloud environment carry more risk than others. Use risk-based controls to prevent high-priority security threats. Identify gaps before they turn into costly violations, and assign resources to address the most critical threats first. This is especially important to consider as you adopt tools like AI assistants. **4. Use Automated Reporting Tools** Manual audits often miss critical errors or become outdated quickly. Automated systems provide detailed, up-to-date compliance reports you can use during audits or to assess progress. With these systems in place, compliance teams can focus on improving systems instead of gathering paperwork. **5. Collaborate Across Teams** Compliance shouldn’t be the responsibility of just one team. Your development, operations, and security teams need to work together to share responsibility. Foster workflows that help your teams address security and compliance at every step of development and deployment, making it easier to prevent violations in the first place. ### Question: How Does Automation Improve Compliance Monitoring? ### Answer: Automation saves time by continuously monitoring for issues such as configuration flaws or noncompliant resources. Automated tools quickly identify risks and fix issues before they result in fines, breaches, or security violations. They can also generate detailed reports, taking the guesswork out of compliance. ### Question: How Do Cloud Providers Help Customers Meet Compliance Standards? ### Answer: Cloud providers secure their servers, storage, and network infrastructure. They also offer tools for monitoring, encryption, and access controls. However, customers are responsible for securing their data, managing permissions, and configuring settings. This shared responsibility requires companies to actively manage their compliance efforts. ### Question: What Are Some Common Causes of Compliance Failures in Multi-Cloud Systems? ### Answer: Compliance failures often happen because of misconfigured access controls, unclear responsibility for security tasks, or lack of visibility across providers. Shadow IT and unmanaged data sprawl can also cause issues by creating blind spots. These gaps leave organizations vulnerable to violations, breaches, and audit delays. ### Title: Comparison: IT vs. OT Security: Understanding Key Differences ### Description: Learn the essentials of IT vs. OT security, including risks, strategies, and the role of Zero Trust in protecting converged infrastructures ### URL: https://www.zscaler.com/zpedia/it-vs-ot-security-understanding-key-differences ### Question: What is the difference between IT and OT security? ### Answer: IT (Information Technology) security focuses on protecting data, applications, and systems in computer networks, such as email servers or corporate databases.

The goal, ultimately, is to become more agile so as to better meet the needs of their users, partners, and customers. With this push toward cloud strategies, the public cloud has effectively become the new enterprise data center. At the same time, hybrid and multicloud environments have become the norm. In fact, IDC Research predicted that use of the public cloud for generative AI platforms, developer tools, and infrastructure would surpass that of on-premises systems by the end of 2025. It's easy to see the appeal. Cloud platforms offer unprecedented speed and reach, with access to hundreds of services at the click of a button. Developers can spin up new environments in moments. Setup and maintenance are dramatically easier than on-premises infrastructure. In short, the cloud continues to redefine what's possible. ### Question: Top 4 Security Challenges in Multi-Cloud Environments ### Answer: However, cloud adoption is giving rise to new security challenges, especially for organizations still using traditional security architectures to secure their clouds. They struggle with: - **Enforcing consistent security policy across multiple platforms.** Gaps in enforcement increase the risk of data breaches and unauthorized access. - **Maintaining visibility and control over users, traffic, and shadow IT.** Dispersed traffic and IT complexity create blind spots that attackers can exploit. - **Meeting compliance standards across jurisdictions and providers.** Weak or misconfigured data security can expose sensitive data and lead to failed audits. - **Managing identities and least-privileged access to sensitive data.** Excessive permissions or poor oversight can leave sensitive data vulnerable to breaches. ### Question: Traditional Security vs. Multi-Cloud Environments ### Answer: *Did you know? Using traditional security like VPNs and firewalls in multi-cloud increases your attack surface exponentially, making you more vulnerable to breaches* | **Traditional Security** | **Challenges in Multi-Cloud Environments** | |---|---| | Designed for on-premises, data center environments | Unable to effectively handle dynamic, scalable workload communication in the cloud | | Relies on routable networks, firewalls, and VPNs | Routable networks increase attack surfaces and make workloads vulnerable to compromise and lateral movement | | Requires virtual firewalls for securing workloads | Virtual firewalls in multi-cloud setups create complex and difficult-to-manage architecture | | Uses legacy approaches to connect workloads | Inefficient and costly when connecting workloads across clouds or between workloads and the internet | | Lacks built-in scalability for additional security capabilities | Additional capabilities like DLP and TLS/SSL inspection require separate virtual appliances, complicating deployment | | Creates a larger attack surface due to dependence on network appliances | Attackers can exploit IP addresses of deployed virtual firewalls, compounding risks | | Operates on implicit network trust | Allows attackers who compromise one workload to laterally move to others, exposing sensitive data | ### Question: Securing Multi-Cloud Environments with Zero Trust ### Answer: Securing today's increasingly cloud-reliant enterprise environments requires a different approach. Rather than security designed around networks, they need an architecture that treats security as foundational to the design and operation of the network. In short, they need a [zero trust architecture](/resources/security-terms-glossary/what-is-zero-trust-architecture). Zero trust enforces least-privileged access, enabling direct workload-to-workload and workload-to-internet communication without implicit trust. When delivered from the cloud, zero trust leverages the cloud’s scalability to support full TLS/SSL inspection at scale, overcoming the bandwidth and resource limitations of traditional architectures. By centralizing security and configuration management in the cloud, organizations can enforce consistent policies across multi-cloud environments while simplifying operations. This new, modern approach: - **Eliminates the attack surface.** Unlike with a legacy approach built on a routable network, workloads become effectively invisible to threat actors. - **Delivers scalable threat and data protection.** Full inline TLS/SSL content inspection and DLP capabilities enable robust security at scale. - **Prevents lateral threat movement.** Providing direct connectivity with no connection to a network renders [lateral movement](/zpedia/what-is-lateral-movement) impossible. - **Reduces costs and complexity.** Centralized management of cloud configurations and security, along with direct connectivity, saves time and effort. ### Question: Secure Workload-to-Workload Traffic ### Answer: Securing workload-to-workload connectivity, both across multiple clouds and within individual VPCs, is also crucial. This involves routing all such traffic through a central zero trust platform to enforce policies and authenticate connections using identity and context. Key capabilities include: - **Secure multi-cloud and multi-region connectivity** to ensure workloads in different clouds or regions can exchange data safely - **Inter-VPC/VNET connectivity** that routes traffic through a central security platform to enforce zero trust principles - **Preventing lateral threat movement** by removing pathways attackers could exploit - [**Zero trust network access (ZTNA)**](/resources/security-terms-glossary/what-is-zero-trust-network-access) to eliminate the attack surface and ensure workloads don’t connect directly to routable networks For instance, traffic traveling between VPCs could be routed through a private service edge, where secure connections are brokered between source and destination apps. ### Question: How Zscaler Can Help ### Answer: Zscaler delivers comprehensive zero trust security for multi-cloud workloads with the cloud native Zscaler Zero Trust Exchange™ platform. - Enforce comprehensive threat and data security with standard controls across environments - Eliminate lateral movement with segmentation between and within clouds, VPCs, and VMs - Reduce complexity and costs by eliminating firewalls, proxies, and expensive private connectivity - Deploy in the form factor that suits your operations, using a virtual machine or managed gateway ### Question: How Do Multi-Cloud Environments Impact Regulatory Compliance? ### Answer: Multi-cloud environments complicate compliance as organizations must meet differing regulations across regions and providers. Strong data governance practices, combined with tools that track compliance metrics and enforce policies, help prevent security violations and maintain regulatory alignment. ### Question: What Role Does Identity Management Play in Multi-Cloud Security? ### Answer: Identity management ensures only authorized users access sensitive cloud resources. Enforcing least-privilege principles and using tools like multi-factor authentication (MFA) helps reduce risks from human error, insider threats, and credential-based attacks across multi-cloud platforms. ### Question: What Are Common Threats to Multi-Cloud Security? ### Answer: Common threats include misconfigurations, unpatched vulnerabilities, shadow IT, and unauthorized access. These issues expand the attack surface, allowing cybercriminals to exploit weak points. Proactive monitoring, regular audits, and advanced security measures help mitigate these risks effectively. ### Title: Network Firewall vs. NGFW vs. Zero Trust Firewall ### Description: Discover key differences between network firewalls, next-generation firewalls (NGFW) and Zero Trust Firewall, with use cases to protect against cyberthreats. ### URL: https://www.zscaler.com/zpedia/traditional-firewall-vs-zero-trust-firewall ### Question: What are the core differences between Network Firewalls, NGFWs, and Zero Trust Firewalls? ### Answer: - **Network Firewall:** Focuses primarily on basic packet filtering based on IP addresses, ports, and protocols.

With scalability issues, limited controls, and inherent vulnerabilities, VPNs are increasingly being replaced by zero trust solutions for enterprise security. ### Question: How VPNs Work: A Brief Overview ### Answer: [VPNs](https://zpedia/what-is-a-vpn) operate by creating encrypted tunnels between your device and a remote server, shielding your internet traffic from prying eyes. This process, known as VPN tunneling, encapsulates data packets within a secure "tunnel" and protects them using encryption protocols. While this mechanism provides a level of privacy and security over public networks, it has inherent limitations in handling modern demands for scalability and performance. VPNs were originally designed for a time when fewer people required remote access, but their architecture struggles to accommodate the needs of today’s distributed workforces. At the heart of VPN functionality are the protocols that govern these tunnels. Commonly used protocols include OpenVPN, IKEv2, and IPsec. OpenVPN is known for its flexibility and encryption, while IKEv2 (Internet Key Exchange version 2) maintains stable connections during network changes—such as switching between Wi-Fi and mobile data. IPsec (Internet Protocol Security) provides encryption and authentication protocols designed for secure communication at the network layer. While these protocols aim to secure traffic, their effectiveness is only as strong as the implementation and infrastructure of the VPN service. By establishing a "virtual" private network across public infrastructure, VPNs allow users to access the internet as though they were operating within a private, secured environment. However, this approach is inherently tied to trust in the VPN provider itself, which can be a critical weak point. Additionally, VPNs rely on perimeter-based security models and broad access, making them increasingly ill-suited for the demands of modern businesses. While they provide basic masking of IP addresses and traffic encryption, they were not designed to scale effectively for large, remote workforces or cloud-first environments. ### Question: 5 Key Components of VPN Security ### Answer: When evaluating the security of a VPN, it’s crucial to understand the core technologies and features that determine its effectiveness. Each component plays a role in protecting sensitive data, but their implementation and reliability can vary significantly across providers. **Data encryption:** VPNs rely on encryption standards like AES-256 to scramble data, making it unreadable to unauthorized parties. This level of encryption is considered strong but can be compromised by weak implementation or misconfiguration. **Authentication methods:** Strong authentication protocols, such as multifactor authentication (MFA), add an essential layer of security to VPN access. However, not all VPN providers enforce robust authentication, leaving systems vulnerable to unauthorized access. **Kill switch**: A kill switch halts internet traffic if the VPN disconnects unexpectedly, preventing unprotected data transmission. This feature is critical to maintaining security but isn't universally implemented or reliable across all VPN services. **Leak protection:** DNS, IP, and WebRTC leak protection ensures that users' real identities and locations are not inadvertently exposed. Without these safeguards, even a secure VPN connection can fail to protect sensitive data. **Logging policies:** A strict no-log policy ensures that VPN providers do not store records of user activity. Without this assurance, user data could become accessible to third parties, undermining privacy and security. While these components are foundational to VPN security, their effectiveness depends heavily on the provider's infrastructure, policies, and implementation. In modern cybersecurity, VPNs often fall short of addressing the granular access controls and scalability required for today’s remote work and cloud-focused environments ### Question: Common VPN Security Threats ### Answer: VPNs are often marketed as a secure solution for online privacy and [data protection](/resources/security-terms-glossary/what-is-data-protection), but they are not without vulnerabilities. Understanding these common [threats](/learn/threats-and-vulnerabilities) is essential for evaluating their limitations in protecting sensitive information. [**Man-in-the-Middle (MiTM) attacks:**](/zpedia/what-is-a-man-in-the-middle-attack) Poorly configured or insecure VPN connections can expose users to MiTM attacks, where an attacker intercepts and potentially alters communications between two parties. Inadequate encryption or authentication can leave users vulnerable, making VPNs ineffective in mitigating such risks. **Data leakage:** VPNs are designed to mask IP addresses and encrypt traffic, but vulnerabilities like IP or DNS leaks can expose user information. These leaks can result from software misconfigurations or poorly implemented VPN infrastructure, undermining the privacy VPNs aim to provide. [**Malware**](/resources/security-terms-glossary/what-is-malware) **risks with free VPNs:** Free VPNs often monetize their services in questionable ways, embedding malware or tracking software to harvest user data. This compromises user privacy and can lead to broader [cybersecurity](/resources/security-terms-glossary/what-is-cybersecurity) risks, such as ransomware infections or data breaches. **Credential theft:** VPNs are only as secure as the credentials used to access them. Weak or reused passwords, combined with [phishing](/resources/security-terms-glossary/what-is-phishing) threats, can lead to stolen VPN credentials. Attackers who gain access to a VPN account can exploit it to infiltrate sensitive systems. These vulnerabilities highlight the limitations of VPNs in providing comprehensive security. Organizations relying on VPNs for remote access should consider alternative solutions that address modern security challenges. ### Question: Are VPNs Enough for Enterprise Security? ### Answer: **Limitations of VPNs** **Scalability challenges:** VPNs struggle to scale effectively with the growing demands of remote workforces. Expanding VPN infrastructure to accommodate more users often requires significant resources and can result in performance bottlenecks. **Speed reduction:** VPN connections frequently introduce latency, particularly when users connect to geographically distant servers or when many users are on the network simultaneously. This can hinder productivity and degrade the user experience. **Perimeter-based security:** VPNs rely on a perimeter-based security model, which grants broad access to internal resources once authenticated. This outdated approach leaves enterprises vulnerable to [insider threats](/zpedia/what-are-insider-threats), credential theft, and [lateral movement](/zpedia/what-is-lateral-movement) across the network. **Lack of granular access control:** VPNs typically cannot enforce [least-privilege principles](/resources/security-terms-glossary/what-is-least-privilege-access) or segment access based on user roles or device posture, making it difficult to align with modern security best practices. **Potential for logging:** Depending on the VPN provider, user activity may be logged, posing privacy and compliance risks. This undermines the very security and anonymity VPNs are supposed to provide. **Why Is Zero Trust Better Than VPN?** [Zero trust network access (ZTNA)](/resources/security-terms-glossary/what-is-zero-trust-network-access) offers a scalable, modern alternative to traditional VPNs. Unlike perimeter-based VPNs, [zero trust](/resources/security-terms-glossary/what-is-zero-trust) operates on the principle of "never trust, always verify," providing secure, application-specific access instead of broad network-level access. Granular access control: ZTNA ensures users are granted access only to specific resources based on identity, device posture, and contextual risk, eliminating the broad access inherent in VPNs. **Scalability and performance:** Zero trust solutions provide[ secure, direct access](/learn/secure-remote-access) to resources without backhauling traffic through a VPN or data center, improving performance and scalability. **Integrated threat protection:** Modern zero trust platforms integrate features like malware inspection, data loss prevention, and traffic analysis, addressing threats VPNs cannot mitigate effectively. **Cost-effective and cloud native:** Zero trust architectures are inherently more scalable and cost-efficient, simplifying management and reducing IT overhead compared to VPN infrastructures. ### Question: Zero Trust vs. VPN ### Answer: | **Aspect** | **VPN** | **Zero Trust Access Model** | |---|---|---| | **Access Model** | Broad, network-level access | Granular, application-specific access | | **Security Approach** | Perimeter-based, "trust but verify" | Identity-driven, "never trust, always verify" | | **Scalability** | Struggles with remote workforce demands | Cloud native, easily scalable | | **Performance** | Latency due to backhauling traffic | Direct-to-resource for low-latency access | | **Threat Protection** | Limited, reactive measures | Integrated, proactive threat detection | | **Management Complexity** | High, with significant IT overhead | Simplified, policy-driven access management | ### Question: What Are the Main Security Flaws of VPNs? ### Answer: VPNs suffer from scalability challenges, lack of granular access control, and perimeter-based security models. They can also experience data leaks, poor implementation, and logging policies that undermine user privacy and enterprise security. ### Question: Why Are VPNs No Longer Sufficient for Enterprise Security? ### Answer: VPNs were built for simpler network needs. They struggle with modern demands like remote workforces and cloud environments, offering broad access instead of resource-specific controls. Zero trust solutions address these shortcomings with enhanced scalability and security. ### Question: How Does Zero Trust Compare to VPNs for Secure Access? ### Answer: Zero trust provides application-specific access based on identity and risk, eliminating broad network access provided by VPNs. It enhances scalability, performance, and security while addressing modern enterprise needs like remote work and cloud-native environments. ### Title: Advanced Persistent Threats: Characteristics & Defense | Zscaler ### Description: Learn about APTs: traits, examples, and strategies to detect and defend against them using Zscaler's advanced security solutions. ### URL: https://www.zscaler.com/zpedia/what-are-advanced-persistent-threats-apts ### Question: What Are Advanced Persistent Threats (APTs)? ### Answer: Advanced persistent threats (APTs) are sophisticated cyberattacks launched by skilled adversaries, designed to steal sensitive data, conduct espionage, or disrupt operations over long periods of time. ### Question: What Are the Characteristics of Advanced Persistent Threats (APTs)? ### Answer: APTs are quite different from opportunistic attacks like broad-spectrum phishing, which tend to rely on mass exploitation tactics and can be carried out even by unskilled actors. Some of the defining traits of APTs are: - **Highly targeted nature:** APTs are carefully built to breach specific organizations, industries, individuals, or governments. Their targets usually possess valuable or sensitive data the attackers can manipulate, destroy, or sell. - **Long-term presence:** APTs are designed to stay undetected inside a network for months or even years. This gives attackers time to carefully analyze their target as well as increase the value and volume of their attack. - **Stealth and evasion:** APTs use techniques that basic security measures overlook. Some of the most common strategies are encryption, masquerading as legitimate code or apps (spoofing), and self-rewriting (polymorphism). - **Nation-state or organized crime backing:** APTs are often sponsored by government or underworld entities pursuing political agendas, competitive advantages, or profit. Threat actors can use these resources to access specialized tools and exploits. ### Question: How Advanced Persistent Threats Work? ### Answer: APTs follow a staged life cycle to infiltrate a target, establish control, and avoid detection. The key stages are: 1. **Reconnaissance:** Attackers collect intel on their target to find the ideal angle of attack. This can include details on the target's network, apps, users (e.g., names, login credentials), partners, etc. 2. **Initial compromise:** Attackers gain access to the target network, often through social engineering (e.g., [spear phishing](/resources/security-terms-glossary/what-is-spear-phishing) emails, business email compromise), zero day exploits, or watering hole attacks. 3. **Establishing a foothold:** Attackers deploy malware such as remote access trojans (RATs) or backdoors, enabling them to regain access if their original entry point is closed. 4. **Privilege escalation:** Attackers use stolen login credentials or exploit internal security flaws (e.g., lax access policies, misconfigurations) to gain high-level permissions or admin access. 5. [**Lateral movement**](/zpedia/what-is-lateral-movement)**:** Attackers use their new privileges to move through the network and remain undetected, further strengthening their foothold while they navigate the environment. 6. **Data exfiltration:** Attackers transfer valuable data (e.g., intellectual property, financial records, customer information) to an outside location they control. Often, they encrypted the data or embed it in legitimate traffic to avoid detection. 7. **Covering tracks:** To maintain access to the network and continue evading detection, attackers may change or delete logs, change timestamps, and more. ### Question: Who Launches Advanced Persistent Threats? ### Answer: APT attackers largely fall into one of a few categories: - Nation-state actors - Hacktivist groups - Cybercriminal organizations - Externally motivated insiders The actors behind APTs are highly skilled hackers, usually with ample resources and financial backing that give them access to advanced methods and tools. Their sponsors can be organized criminal enterprises out for profit, but are primarily nation-state groups involved in cyber espionage. Groups based in China, Iran, North Korea, and Russia are regularly linked to high-profile APT campaigns. ### Question: Real-World Examples of APT Attacks ### Answer: APTs present an active and growing threat. Some recent incidents include: - [**North Korean remote workers in the West**](/blogs/security-research/pyongyang-your-payroll-rise-north-korean-remote-workers-west)**:** North Korean threat actors have been using social engineering, GenAI, and stolen data—including source code, personal data, and crypto wallets—to secure remote work opportunities in Western countries. - [**Kimsuky (APT43)**](/blogs/security-research/kimsuky-deploys-translatext-target-south-korean-academia)**:** This DPRK-backed threat group uses various techniques, including malicious Chrome extensions, to steal login credentials, tracking data, and more from South Korean think tanks, government agencies, and schools. - **Earth Baku (APT41):** This China-based threat actor uses the stealthy [DodgeBox](/blogs/security-research/dodgebox-deep-dive-updated-arsenal-apt41-part-1) loader to deliver [MoonWalk](/blogs/security-research/moonwalk-deep-dive-updated-arsenal-apt41-part-2) backdoor malware. Originally known for targeting organizations in Southeast Asia, the group has expanded its efforts to the EMEA region as well. Meanwhile, other less recent APT attacks have left notorious legacies behind: - [**SolarWinds attack**](/resources/security-terms-glossary/what-is-the-solarwinds-cyberattack) **(2020):** Russian nation-state actors deployed trojanized updates to the SolarWinds Orion software, enabling them to install malware on the systems of roughly 18,000 SolarWinds customers, including agencies of the US government. - **Stuxnet (2010):** Allegedly part of a covert cyber sabotage operation, this worm malware disrupted industrial processes in Iranian nuclear facilities, critically damaging an estimated 1,000 nuclear centrifuges. - **Operation Aurora (2009):** China-backed threat actors used a zero day exploit in the Internet Explorer web browser to steal data from dozens of large companies, including Adobe, Google, and Yahoo. The incident led Google to discontinue operations in China. ### Question: Impacts of APT Campaigns? ### Answer: APT attacks can have major repercussions, and data breaches are only the beginning. In the aftermath of a breach, victims can face financial losses as well as legal, regulatory, and reputational consequences, sometimes charting a very long road to recovery. If an APT disrupts critical operations or systems, it can lead to interruptions in supply chains, manufacturing, or essential utilities, or even cause broader political or economic turmoil. The Operation Aurora and Stuxnet attacks in particular showcase how APTs can contribute to long-term sociopolitical and geopolitical tensions. ### Question: How to Detect and Defend Against APTs ### Answer: APT groups expertly design their attacks to be difficult to detect—but it's not impossible. Defending against APTs requires a robust, proactive security architecture that delivers: - **Complete visibility:** Continuous monitoring eliminates blind spots across endpoints, networks, and clouds to detect suspicious activity. - **Anomaly detection:** AI-powered tools can identify unusual patterns, such as abnormal traffic flows or disguised attempts to exfiltrate data. - **Integrated threat intelligence:** Real-time threat intelligence links external data to internal activity, enabling quicker identification of APT-specific tactics. - **Proactive threat hunting:** Expert threat hunters can seek activities like privilege escalation or lateral movement before they trigger automated alerts. - **Advanced detection tools:** Tools like endpoint detection and response (EDR), intrusion detection systems (IDS), and sandboxes can uncover signs of APT behavior that traditional tools miss. - **Zero trust architecture:** Least-privileged access controls and continuous verification of identities and devices minimize the risks of lateral movement or escalation. ### Question: How Are APTs Different from Other Cyberattacks? ### Answer: Unlike typical cyberattacks that are opportunistic and short-term, APTs are strategic, covert, and sustained. They are meticulously crafted to evade detection while pursuing long-term objectives like espionage or data theft. Furthermore, the attackers are generally highly skilled, organized hackers with third-party financial backing. ### Question: What Are Common Signs of an APT Attack? ### Answer: APT groups design their attacks for stealth, making them challenging to detect. However, various anomalous actions can indicate APTs, such as unusually large data transfers, sudden configuration changes, or spear phishing attempts. Compromised users may be seen logging in at unusual times or from unknown devices, making atypical access requests, or frequently making unknown outbound connections. ### Question: Which Industries Are Most at Risk of APT Attacks? ### Answer: The top targets of APTs house data with high strategic or monetary value, or high potential for disruption. This often includes critical infrastructure organizations—such as government and defense, financial services, healthcare, utilities, transportation, and communications—as well as those with sensitive intellectual property, such as manufacturing, research and development, and education. ### Title: What Are DLP Policies?

How They Secure Data Across Cloud Platforms ### Answer: DLP policies ensure robust data security across multiple cloud platforms by identifying and classifying different types of sensitive data, then preventing data from leaving secure environments. These measures help guard intellectual property in multicloud setups, protect personal data, and foster regulatory compliance—ultimately safeguarding organizational interests. ### Question: How do DLP policies secure data in multicloud setups? ### Answer: They classify, monitor, and control sensitive data across platforms. ### Question: What challenges arise in multicloud data security? ### Answer: Complexity, visibility gaps, and compliance issues can occur. ### Question: How do DLP tools protect data during transfers? ### Answer: They use inline SSL inspection and DLP dictionaries. ### Question: Which features make DLP policies effective for the cloud? ### Answer: Granular controls, context-aware enforcement, and integration. ### Question: What are the key benefits of DLP in multicloud environments? ### Answer: Enhanced visibility, better compliance, and data protection. ### Question: Understanding DLP Policies ### Answer: [Data loss prevention (DLP)](/products-and-solutions/data-loss-prevention) is a security solution that helps organizations preserve sensitive data from leaks and unauthorized access. By monitoring user activity across cloud infrastructures, these policies keep an eye on data at rest and in motion. They also ensure personal data is safely stored, maintaining accountability and integrity at every step. ### Question: What Do DLP Policies Protect? ### Answer: DLP policies can classify different subsets of information to enforce stricter controls on high-risk assets, such as intellectual property or personally identifiable details. At the same time, they streamline processes for preventing data from being inadvertently shared externally. With their help, a security team can strike a balance between productivity and protection. ### Question: How Do DLP Policies Work Across Cloud Environments? ### Answer: Many DLP platforms are cloud-based, allowing organizations to protect files across multiple cloud platforms and on-premises environments. They also support robust encryption measures, so administrators can encrypt data at the source or during transfer. Because of this flexible configuration, data leaks become far less likely, and compliance efforts are more manageable. ### Question: Challenges of Securing Data in Multicloud Environments ### Answer: Safeguarding information across various cloud platforms can feel daunting, especially when each environment operates differently. Before implementing DLP, organizations often struggle with key hurdles that complicate [data security](/zpedia/what-is-data-security) and hamper operational efficiency. **Complexity in Policy Enforcement** Managing security policies across a sprawling network of cloud storage services and on-premises data centers often results in fragmented controls and inconsistent rule application. Each platform typically has its own configuration settings and access mechanisms, making it difficult to enforce a unified set of policies. This complexity can introduce vulnerabilities, as gaps or overlaps in enforcement may inadvertently expose sensitive data. **Visibility and Compliance Gaps** The lack of centralized monitoring in multicloud environments makes it challenging to track user activities and data movements consistently across all platforms. These blind spots cannot only hinder the detection of suspicious behavior and potential data leaks, but also complicate efforts to maintain regulatory compliance. Varying standards and requirements from different providers further amplify the difficulty of meeting industry mandates and ensuring that sensitive data remains protected. ### Question: How DLP Policies Work Across Multiple Cloud Platforms ### Answer: Implementing DLP policies in a [multicloud](/resources/security-terms-glossary/what-is-multicloud) environment requires a methodical approach, blending technology with practical controls. Here are some core steps illustrating how these solutions operate across diverse platforms: 1. **Discovery and Classification** The DLP engine performs comprehensive scans across disparate data repositories—including endpoints, mobile devices, and remote servers—within and between cloud platforms. This process identifies and categorizes sensitive information according to regulatory requirements or internal company standards, such as personally identifiable information (PII) or intellectual property. Accurately labeling each data type ensures that subsequent DLP controls are context-aware and tailored to the unique sensitivity of the content. 2. **Policy Enforcement** After data has been classified, DLP policies are systematically applied to govern access and usage. These policies can automatically restrict or grant permissions based on a combination of user roles, geographical location, device security posture, and the data’s context. This ensures that only authorized individuals can interact with high-risk datasets, minimizing opportunities for accidental or intentional data leaks. 3. **Encryption and Tokenization** DLP solutions employ strong encryption or tokenization techniques to protect sensitive data as it moves between different cloud infrastructures. By converting clear text into indecipherable formats, DLP tools shield information from interception or unauthorised viewing during transfers and while at rest.

Explore benefits, challenges, and best practices for a smooth migration to modern cloud protection. ### URL: https://www.zscaler.com/zpedia/migrating-to-a-cloud-native-security-platform ### Question: What Does Migrating to a Cloud Native Security Platform Involve? ### Answer: Migrating to a cloud native security platform involves replacing on-premises hardware appliances as well as virtual appliances, wherever they may be deployed. With a single cloud-delivered platform providing a variety of functionality like DLP and ATP as a service, organizations can streamline and enhance their security, helping them to keep pace with modern digital demands, evolving threats, and highly distributed environments. ### Question: Understanding Cloud Native Security Platforms ### Answer: In the early days of digital transformation, security made sense as a stack of appliances inside the company’s headquarters—where users and data mostly lived. But as organizations opened more branches and added remote work, maintaining appliances for every site—or backhauling traffic to a central location—became unwieldy and inefficient. Even moving appliances to virtualized instances in the cloud didn’t fundamentally change the model: teams were still managing hardware or virtual boxes, patching systems, and juggling maintenance across many locations. Cloud native security takes a different approach, delivering protection as a streamlined service directly from a global cloud platform, not an appliance in a rack or virtual machine. There’s no hardware to maintain, and no need to route traffic through a central hub just to access security controls. With [security delivered as a service](/resources/security-terms-glossary/what-is-security-as-a-service), organizations gain flexibility—security is available wherever users, devices, and applications are, without the headaches of appliance management or location-based limitations. This shift has also transformed how teams manage security day-to-day. Instead of wrestling with countless point products and multiple dashboards, businesses can unify controls under a single cloud native platform. Capabilities like authentication, [data loss prevention (DLP)](/zpedia/what-is-data-loss-prevention-dlp), analytics, and compliance monitoring are integrated, so admins work from one interface, see the full picture, and respond more efficiently. Ultimately, cloud native security matches the speed and reach of the way people work today, letting organizations stay agile and protected as they grow. ### Question: Why Migrate: Key Benefits of Cloud Native Security ### Answer: Elevating security through a cloud native model can transform how enterprises operate and [protect their data](/resources/security-terms-glossary/what-is-data-protection).

Shield infrastructure from data loss, hackers, and malware with advanced security technologies. ### URL: https://www.zscaler.com/zpedia/what-is-5g-security ### Question: What Is 5G Security? ### Answer: 5G security is an area of wireless network security focused on fifth-generation (5G) wireless networks. 5G security technologies help protect 5G infrastructure and 5G-enabled devices against data loss, cyberattacks, hackers, malware, and other threats. Compared to previous generations, 5G makes greater use of virtualization, network slicing, and software-defined networking (SDN), making it vulnerable to new kinds of attacks. ### Question: Why Is 5G Security Important? ### Answer: As 5G technology is rolled out in more and more countries, it will have a huge impact on critical infrastructure and global industries. However, the technological advancements of 5G also come with new and heightened cybersecurity risks that telecommunication operators and their customers can’t ignore, including: - **Expanded attack surface:** More connected devices and more infrastructure migrating into the cloud create a wider range of entry points for cybercriminals to exploit. And because 5G enables millions of devices per square kilometer to interconnect (vs. tens of thousands of 4G LTE and Wi-Fi enabled devices), one exploited device could lead to cascading vulnerabilities compromising whole ecosystems. - **Network slicing vulnerabilities:** 5G infrastructure enables network slicing—creating multiple virtual network segments side-by-side in a 5G network, each serving specific apps, companies, or industry verticals. This is efficient, but it opens the door to intra-slice attacks and other new risks. Slices need to be securely isolated and segmented to prevent attackers from moving laterally. - **Supply chain risks:** The adoption of 5G relies on a global supply chain of hardware, software, and services. Ensuring the security of all components is challenging, as malicious actors may attempt to [compromise one or more points in the hardware/software supply chain](/resources/security-terms-glossary/what-is-a-supply-chain-attack) to infiltrate 5G networks and devices. - **Data privacy concerns:** 5G networks support massive data exchange and processing, creating privacy concerns around the ever-increasing amounts of personal/sensitive data involved. Unauthorized data access often leads to identity theft, fraud, and other misuse. - **Threats to critical infrastructure:** As 5G technology integrates with national critical infrastructure like power grids, transportation systems, and healthcare facilities, a breach could have serious implications for public safety, patient health, industrial operations, national security, or even economic stability. While 5G is poised to drive the next generation of technological transformation across industries, governments, and more, it also comes with greater (and in some cases, unquantified) security risks. ### Question: 5G Security Benefits ### Answer: Service providers and mobile network operators have a responsibility to ensure the privacy, security, and integrity of customer data and operations on their 5G networks. With effective security measures in place, providers and operators can: - Leverage real-time security monitoring and analysis to more quickly detect and respond to potential security threats - Minimize the impact of cyberattacks and reduce the associated costs and reputation damage - Demonstrate a commitment to the integrity of customers’ data and operations, building their loyalty and trust With smart manufacturing—Industry 4.0—in full swing, businesses using internet of things (IoT) devices are eager to use 5G networks to keep their IoT devices connected and performing. ### Question: How Does 5G Work? ### Answer: 5G uses a broad mix of radio bands that push speeds of up to 10 Gbps (10 to 100 times faster than 4G-LTE), which will soon make web experiences that feel “fast enough” today feel like the days of dial-up. 5G offers ultra-low latency, which translates to near-real-time network performance. Where a packet of data could previously take 20 to 1,000 milliseconds (ms) to get from your laptop or smartphone to a workload, 5G can cut that time down to a few milliseconds when the use case demands it. Naturally, there’s more to it than that—physical speed alone doesn’t reduce latency. Various factors, including distance, bandwidth congestion, software and processing deficiencies, and even physical obstacles, can contribute to high latency. To achieve ultra-low latency, what compute resources need most is to be closer to end user devices. Having servers located physically close to end-user devices is called “Edge compute.” The type of Edge compute varies by latency range: 1. **Far Edge:** Between 5 and 20 ms latency; farthest from the cloud and closer to devices 2. **Near Edge:** 20+ ms latency; nearer to the cloud than to devices 3. **Deep Edge:** Less than 5 ms away from devices ### Question: How Does 5G Work with Edge Computing? ### Answer: 5G technology and edge computing (distributed computing that enables data processing and storage at the edge of the network) are transforming the way we communicate and do business. Enhancements in speed, real-time data transmission, and mobile network density are the cornerstones of modern connectivity—delivering the capacity essential for IoT-connected devices, automation, VR and augmented reality interfaces, smart cities, and more. ### Question: 5G Security Challenges ### Answer: The 5G standard explicitly calls out that security is a key design principle. This usually means you’ll read that “5G is secure by design.” In other words, 5G was designed to be secure. The reality is that 5G security is limited to the network itself. It doesn’t extend to the devices and workloads customers will use to communicate through a 5G network. So, while 5G means more data, services, devices, operating systems, virtualization, and use of the cloud, it also means the 5G attack surface is huge, and Edge workloads are many attackers’ new preferred targets. 5G security has a steep learning curve, and many security professionals, enterprise IT, and sub-contractors lack the knowledge and experience to protect apps running on 5G networks. As the joining of highly-scaled IT systems to wireless telecommunications networks, 5G needs cybersecurity specialists skilled in both worlds. ### Question: 5G and Zero Trust for Maximum Security ### Answer: Zero trust simplifies the protection of 5G/edge workloads and devices, meaning organizations that embrace it will find embracing 5G and its attendant security challenges easier, faster, and safer. Zero trust is the architecture for comprehensive security monitoring, granular risk-based access controls, infrastructure-wide coordinated system security automation, and real-time protection of critical data assets in a dynamic threat environment. ### Question: Is 5G Just a Speed Increase? ### Answer: 4G offers data rates of up to roughly 100 Mbps, while 5G can offer up to 20 Gbps, but 5G offers more than increased data transfer speeds. 4G communications latency, or the delay in data being sent, ranges from about 60-100 milliseconds, whereas 5G latency can be under 5 milliseconds for certain use cases. Regarding bandwidth and the volume of simultaneous connections, a 4G network can support several thousand devices in one square kilometer, while a 5G network can support a million. ### Question: How Does 5G Improve Security? ### Answer: 5G can improve security by providing faster, more reliable, and more secure communication between devices. It also enables real-time security monitoring and analysis because data can be transmitted and received almost instantaneously. Additionally, the use of virtualization and software-defined networking in 5G networks provides greater flexibility and scalability, enabling more efficient and effective security measures to be implemented. ### Question: Why Is 5G More Secure Than Wi-Fi? ### Answer: 5G uses advanced encryption algorithms and protocols that are more difficult to hack than those used by 4G LTE and Wi-Fi, making 5G networks more secure. 5G networks also incorporate multiple layers of defense, such as firewalls, intrusion detection, and prevention systems, encryption, and other security capabilities built into core network functions. ### Title: What Is a Botnet? | Botnet Uses, Examples, and Protection Tips ### Description: Learn what a botnet is, how it works, examples like Mirai, Gafgyt, Mozi, and tips to protect against botnet attacks using advanced cybersecurity solutions. ### URL: https://www.zscaler.com/zpedia/what-is-a-botnet ### Question: What Is a Botnet? ### Answer: A botnet is a network of infected computers or IoT devices under the collective control of a cybercriminal. By issuing remote commands over the internet through malware on the infected machines, a hacker can use a botnet to perform a variety of large-scale cyberattacks, such as distributed denial of service (DDoS), phishing, and cryptomining. Device owners often don’t know their device is part of a botnet at all. ### Question: What Are Botnets Used For? ### Answer: Botnets are used in various types of attacks that benefit in some way from the use of a large number of remotely operated endpoint devices. Some examples of common kinds of botnet attacks are: - **Distributed denial of service:** In a [DDoS attack](/resources/security-terms-glossary/what-is-a-denial-of-service-attack), attackers send traffic from many devices at once to overwhelm the processing or bandwidth capabilities of target servers or infrastructure and prevent normal service delivery. - **Phishing and other email fraud:** Botnets can send large volumes of spam or [phishing](/resources/security-terms-glossary/what-is-phishing) messages from different accounts and IP addresses as part of credential phishing attempts, financial scams, malware campaigns, and more. - **Cryptocurrency mining:** Using the collective processing power of a botnet in conjunction with cryptomining malware, an attacker can mine digital currency without device owners’ knowledge or consent (a.k.a. [cryptojacking](/zpedia/what-is-cryptojacking)). - **Brute force attacks:** Botnets can rapidly perform successive login attempts to access victims’ online accounts, or use credentials exposed in leaks to quickly attempt credential stuffing attacks on multiple websites at once. - **Proxy-based obfuscation:** Attackers can turn botnet devices into [forward proxies](/resources/security-terms-glossary/what-is-forward-proxy) to redirect malicious traffic while hiding their identity and location. They may even sell proxy access to other attackers via the dark web. - **Trojans, keylogging, and packet sniffing:** Botnet malware can be used to monitor and log data the bot sends and receives as well as to capture information users enter into their devices, such as login credentials. ### Question: How Do Botnets Work? ### Answer: Botnets begin with botnet malware, distributed like other types of malware through methods such as phishing emails or vulnerability exploits, that turns infected devices into “bots.” These bots then communicate with a hacker-controlled central server called a command and control (C2 or C&C) server, which the hacker uses to issue instructions to the bots. Besides instructing the bots to perform various attacks, the C2 server can issue updates to the malicious software to improve or alter the botnet’s functions and capabilities, making it more difficult to detect and defend against. On top of that, a single botnet can consist of hundreds or even many thousands of widely distributed devices, the owners of which may never know their devices are part of a botnet. ### Question: How Do Botnets Evade Detection? ### Answer: Botnet malware is engineered to escape notice by operating covertly in the background with advanced techniques such as the use of polymorphic code, domain generation algorithms (DGAs), and encryption. These methods enable the malware to change its appearance and alter or hide its communication pathways, making it difficult for conventional [cybersecurity](/learn/cybersecurity) measures, such as signature-based antivirus or traditional network security hardware, to detect, intercept, or analyze malicious traffic linked to botnet operations. ### Question: How Are Botnets Controlled? ### Answer: Botnet operators (sometimes called bot herders) can control bot devices in two main ways: - **Centralized control**, wherein the C2 server sends instructions to each bot, which do not communicate directly with one another - **Decentralized or peer-to-peer control**, wherein the C2 server sends instructions to just one bot, which in turn communicates with the other bots Centralized botnets are easier to set up than P2P botnets, but they’re also easier to shut down, as hunters can simply locate and disable the central server. Conversely, P2P botnets have considerably higher overhead but are more difficult to shut down, as it’s far more difficult to locate the C2 server among all the intercommunicating devices. ### Question: What Types of Devices Can Be Affected? ### Answer: Practically any internet-connected device can become part of a botnet as long as an attacker can get malware running on it. These devices include: - **Computers, smartphones, and other mobile devices** running all common operating systems - **Servers, routers, and other network hardware** that can further facilitate the spread of attacks - **Internet of things (IoT) and operational technology (OT) devices**, which often lack robust security and, in the case of traditionally “air-gapped” OT systems, were not designed with hyperconnectivity in mind. By exploiting vulnerabilities in IoT devices, attackers can assemble massive botnets capable of launching powerful DDoS attacks. ### Question: Examples of Botnet Attacks ### Answer: The use of botnets remains popular in widespread cyberattacks because of how difficult it can be to definitively shut them down. Here’s a look at some high-profile botnets that have been active in the last several years: 1. **Mirai** uses brute force techniques and remote code execution to infect IoT devices with botnet malware. One of the most prolific IoT malware families for years, Mirai waged what was the largest DDoS attack in history in 2016. 2. **Gafgyt** and its variants infect Linux systems to launch DDoS attacks, having infected millions of IoT devices since 2014. Gafgyt-affiliated botnets have been responsible for DDoS attacks up to 400 Gbps in intensity. 3. **BotenaGo** uses some of the same techniques as Mirai, including brute-force authentication, to infect routers and IoT devices. Written in the open source Go language and available on GitHub, any would-be attacker can modify or release it. 4. **Mozi**, discovered in 2019, primarily exploits IoT devices with weak or default login credentials and infects them with botnet malware. Mozi was responsible for more than 5% of IoT malware in the first half of 2023. 5. **VPNFilter** targets routers and storage devices, specializing in targeting ICS/SCADA devices. Allegedly the creation of the Russian cyber espionage group Fancy Bear, it can exfiltrate data, brick devices, and persist through router reboots ### Question: How to Protect Your Organization Against Botnets ### Answer: With their vast global reach, advanced evasion tactics, encrypted communications, botnet attacks remain a pervasive and accessible threat—especially as open source variants proliferate and the mass of vulnerable targets continues to grow.

By filtering and forwarding internet traffic, it enables improved online privacy and helps protect sensitive information. Designed to manage requests at the network edge, a proxy can block access to harmful sites, enhance security, and optimize overall performance. [Read more.](/zpedia/what-is-a-proxy-server) ### Question: How Does a Proxy Server Work? ### Answer: Proxy servers are often deployed between an internal network and the wider internet. When users send a request—like accessing a web server—the proxy intercepts that request before it reaches its destination. It then evaluates, modifies, or filters the traffic as needed, applying security measures such as content scanning and access controls. Finally, it relays the request to the intended destination (or returns a cached response) if it meets the organization’s policies. At the heart of this process lie three main components: the client (your device), the proxy server itself, and the target resource (such as a website). The proxy receives your request and checks rules in its configuration database. If approved, the proxy forwards the request on your behalf, or if it has previously retrieved the resource, it may serve you the cached content. This approach saves bandwidth, reduces network-based security threats, and provides an additional layer of proxy server security. Additionally, many organizations rely on a secure proxy server to bolster their protective measures, ensuring that sensitive or confidential information isn’t directly exposed to the internet. In some setups, proxies also encrypt data, safeguarding it during transit. By filtering harmful content and providing extra security features, a [cloud proxy server](/resources/security-terms-glossary/what-is-cloud-proxy) can further reduce the likelihood of cyberattacks and [data breaches](/zpedia/what-data-breach). [Read more.](/zpedia/what-is-a-proxy-server) ### Question: Types of Proxy Servers ### Answer: Proxy servers can vary in purpose and configuration. Here are five major types worth understanding: 1. [**Forward proxy:**](/resources/security-terms-glossary/what-is-forward-proxy) This type of proxy accepts client requests from inside a private network and forwards them to the wider internet. Companies commonly use it to enforce content filtering, manage bandwidth, and track usage. 2. [**Reverse proxy:**](/resources/security-terms-glossary/what-is-reverse-proxy) Positioned in front of web server infrastructure, a reverse proxy intercepts requests from the internet and forwards them to internal services. It often helps with load balancing, caching, and enhancing proxy vulnerability mitigation. 3. **Transparent proxy:** A transparent proxy identifies itself to websites, but it does not hide the user’s IP address. It’s often employed by schools or offices to monitor traffic and enforce security measures silently. 4. **Anonymous proxy:** By masking a user’s IP address, an anonymous proxy aims to protect personal information and facilitate anonymity online. It doesn’t disclose the user’s real IP, enhancing privacy but sometimes reducing performance. 5. **High-anonymity proxy:** This option offers an even higher level of privacy, giving no indication that the connection is proxied at all. Users often rely on it when they’re especially concerned about identity theft or want robust online concealment.

[Read more.](/zpedia/what-is-a-proxy-server) ### Question: Proxy Servers in Cybersecurity ### Answer: Beyond convenience and performance, proxy servers play a formidable role in modern [cybersecurity](/resources/security-terms-glossary/what-is-cybersecurity). They stand guard between your network and the internet, scanning requests for signs of malicious intent, with many businesses relying on a cloud proxy server for centralized updates and [advanced threat detection](/resources/security-terms-glossary/what-is-advanced-threat-protection). **Reducing Vulnerabilities** Traditional systems might suffer from direct exposure to the internet, leaving them open to proxy vulnerabilities or other exploits. A well-configured proxy insulates internal assets from direct access, lowering the odds of data breaches. By funneling internet traffic through a single checkpoint, administrators can deploy real-time filtering and inspection routines to sniff out malicious activity. **Managing Distributed Denial of Service (DDoS) Attacks** When handling high volumes of incoming requests designed to overwhelm resources, proxies can help distribute or filter the load. They can also recognize irregular traffic patterns and halt suspicious requests, thereby mitigating the impact of a [DDoS assault](/resources/security-terms-glossary/what-is-a-denial-of-service-attack). This extra layer helps organizations maintain uptime, letting them recover quickly and protect sensitive information in the process. **Preventing Malicious Activity** Secure proxies can systematically block [phishing](/resources/security-terms-glossary/what-is-phishing) links, harmful downloads, and known malicious IPs, ensuring a secure connection by spotting shady web domains and severing connections before they pose any real danger. Over time, collecting insights from proxy logs can further refine the detection of new threats, ultimately bolstering overall security. [Read more.](/zpedia/what-is-a-proxy-server) ### Question: Challenges and Limitations of Proxy Servers ### Answer: Despite their advantages, proxy servers come with potential pitfalls. In the rush to secure networks or optimize bandwidth, it is vital to consider issues such as: - **Latency issues:** By routing traffic through an extra layer, proxies can slow down data retrieval, especially if the server is geographically distant or overloaded. - **Potential misconfiguration problems:** Setting up proxies incorrectly may create security holes, giving [hackers](/zpedia/what-is-a-threat-actor) new angles of attack or introducing unexpected performance bottlenecks. - **Reduced speed:** On busy networks, proxies can become yet another link in the chain that drags performance, especially if they run on outdated hardware or software. - **Limited ability to handle advanced threats:** Proxies alone do not guarantee unwavering protection against sophisticated attacks.

Definition, Risks & Better Alternatives ### Description: Discover how VPN gateways work, their security limitations, and why enterprises are replacing them with identity-centric zero trust solutions like Zscaler. ### URL: https://www.zscaler.com/zpedia/what-is-a-vpn-gateway ### Question: What Is a VPN Gateway? ### Answer: A virtual private network (VPN) gateway is a server-based technology that manages secure connections between endpoints and a corporate network. By encrypting data and enforcing security protocols, it strives to protect remote employees and keep unauthorized users out. Essentially, it acts as the gatekeeper for any remote access with VPN. ### Question: How VPN Gateways Work to Enable Secure Access ### Answer: [VPN](/zpedia/what-is-a-vpn) gateways work by creating encrypted tunnels between a user’s device and the corporate network, ensuring that sensitive information travels safely over the public internet. They rely on various security protocols to establish a trusted link, often using an encryption key to lock down data packets as they move back and forth. In many setups, the VPN server authenticates a remote worker through established credentials, confirming identity before granting them permission to securely access internal resources. Once inside, the VPN gateway security measures monitor network traffic to attempt to maximize connectivity and encrypt data in motion. Despite these protective measures, the inherent flaws of a VPN gateway become evident as organizations scale and bring on more remote employees or expand to remote locations. Traditional site-to-site VPN solutions often struggle with performance and visibility issues, which can make them less flexible in adapting to emerging threats. ### Question: What are the Common Use Cases for VPN Gateways? ### Answer: VPN gateways have historically played a major role in connecting people and devices, although certain use cases are starting to feel outdated given today’s sophisticated security demands. Below are four situations in which a secure VPN gateway might still be deployed, yet each is under scrutiny as more organizations move toward alternative approaches: - **Protecting in-office workers:** Companies sometimes use VPN gateways to control how on-site employees access internal systems. However, as the landscape evolves, traditional VPN tunnels are falling out of favor, with more proactive methods of verification seeing increased adoption. - **Facilitating** [**remote access VPNs:**](/resources/security-terms-glossary/what-is-remote-access-vpn) When teams work outside the office, a virtual private network may grant a path into data centers or shared resources. Today, though, remote access with VPN often can’t match the granularity of [identity-centric](/zpedia/what-is-identity-and-access-management), context-aware models. - **Connecting branch offices (site-to-site VPN):** Remote offices historically relied on permanent VPN connections to link in-house servers and local networks. These fixed network connections can be difficult to manage and increasingly feel like an outdated approach. - **Supporting legacy apps:** Many older applications aren’t cloud-ready and use a VPN gateway for basic security and encryption. Even so, modern solutions offer better controls without forcing all traffic through a perimeter-based structure. ### Question: VPN Gateways: Risks, Limitations, and Performance Issues ### Answer: Although VPN gateways have long served various security purposes, they come with several drawbacks that can hinder an organization’s overall posture. Below are a few common concerns: - **Over-reliance on perimeter:** Focusing on a single entry point leaves systems vulnerable if the gateway is compromised. - **Limited visibility:** Traditional VPN service implementations are unable to determine exactly who is accessing which resource, making forensic or optimization efforts a challenge. - **Performance bottlenecks:** VPN encryption plus the re-routing of data often introduces latency and inefficiencies, especially as user demand skyrockets. - **Complex scaling:** Adding new remote locations or remote employees quickly becomes cumbersome with layered network configurations that aren’t designed to expand gracefully. ### Question: VPN Gateways vs. Zero Trust Security ### Answer: | **Feature** | **VPN Gateways** | **Zero Trust Security** | |---|---|---| | **Security Model** | Perimeter-focused; trusts anyone inside once authenticated | Identity-centric; consistently verifies every user and device | | **Access Control** | Broad; users often see most of the network once connected | Granular; policies define precisely who can access what | | **Scalability** | Complex and resource-intensive to expand | Designed to adapt quickly and easily as needs grow | | **Visibility** | Limited insight into user activity behind the tunnel | Detailed tracking of data flows and user interactions | | **Adaptability** | Slow to update due to static configurations | Rapid, automated changes based on real-time context | ### Question: Why Identity-Centric Zero Trust Is Better ### Answer: Zero trust goes well beyond simply encrypting data; it insists on strict verification of every device and user before granting access. Under this framework, each connection request is scrutinized dynamically to confirm that it poses no risk, thereby reducing the odds of a [breach](/zpedia/what-data-breach). Furthermore, an identity-focused design breaks away from the idea that “once you’re in, you’re trusted,” a concept that has long hampered traditional VPN setups. For enterprises seeking maximum protection, zero trust ensures policy enforcement at all times from any location, thereby minimizing [attack surfaces](/zpedia/what-is-external-attack-surface-management). Whether users are on-premises or working from a remote location, enterprises benefit from continuous authentication that checks context and user privileges, rather than funneling traffic through a single perimeter. This approach is not only more resilient but also more efficient, allowing for greater clarity into threat detection and incident response. ### Question: What Is the Difference Between a VPN Gateway and a VPN Client? ### Answer: A VPN gateway acts as the secure entry and exit point for network traffic, while a VPN client is the software or device users employ to establish a secure connection to that gateway. ### Question: Are VPN Gateways Effective Against Insider Threats or Lateral Movement? ### Answer: Traditional VPN gateways typically grant broad network access once authenticated, making it easier for threats to move laterally. Modern security models recommend fine-grained, context-aware controls to reduce attack surfaces after initial entry. ### Question: Can VPN Gateways Offer Visibility Into User and Device Behavior? ### Answer: VPNs generally lack granular monitoring and cannot always verify device health or user context. In contrast, zero trust platforms continuously assess identity and device posture to better detect suspicious activity in real time. ### Title: What Is a VPN? - How It Works & Types | Zscaler ### Description: Virtual private networks (VPNs) allow clients to connect to servers without exposing themselves to Internet traffic. ### URL: https://www.zscaler.com/zpedia/what-is-a-vpn ### Question: What Is a VPN? ### Answer: A virtual private network (VPN) is an encrypted tunnel that allows a client to establish an internet connection to a server without coming into contact with internet traffic. Through this VPN connection, a user’s IP address is hidden, offering online privacy as they access the internet or corporate resources—even on public Wi-Fi networks or mobile hotspots and on public browsers such as Chrome or Firefox. [Read more](/zpedia/what-is-a-vpn). ### Question: How Does a VPN Work? ### Answer: A VPN works by taking a standard user-to-internet connection and creating a virtual, encrypted tunnel that links the user to an appliance in a data center. This tunnel protects the traffic in transit so that bad actors using web crawlers and deploying [malware](https://cms.zscaler.com/resources/security-terms-glossary/what-is-malware) can’t steal any of the user’s or entity’s information. One of the most common encryption algorithms used for VPNs is Advanced Encryption Standard (AES), a symmetric block cipher designed to protect data in transit. Most often, only authenticated users can send their traffic through the VPN tunnel. Depending on the type of VPN or its vendor, users may have to reauthenticate to keep their traffic traveling through the tunnel and safe from bad actors. [Read more](/zpedia/what-is-a-vpn). ### Question: The History of the VPN ### Answer: Point-to-Point Tunneling Protocol, thought to be the genesis of secure wireless data transfer, was released in 1996. Before PPTP, securely exchanging information between two computers required a hardwired connection, which was inefficient and impractical on a large scale because of the amount of physical infrastructure needed. Therefore, if the security offered by a wire was unavailable, any data being transferred was left vulnerable to attack or theft. With the development of encryption standards and the evolution of the bespoke hardware requirements to build out a secure wireless tunnel, PPTP eventually evolved into what it is today: the VPN server. Able to be applied wirelessly, it saved hassle and costs for businesses in need of secure wireless information transfer. From here, many companies went on to build their own physical and virtual VPN services, including Cisco, Intel, and Microsoft.[ Read more](/zpedia/what-is-a-vpn). ### Question: Types of VPNs ### Answer: VPNs exist to provide convenient security that can serve a smaller-scale need or purpose. Here are some examples of VPNs: 1. **Cloud VPN:** VPNs can be deployed on top of virtual machines in order to “cloud-enable” them. This takes the hardware capability of a VPN and (artificially) adds cloud functionality, such as greater scalability and endpoint protection. While these may be more useful for extended enterprises than a typical standalone VPN appliance, they may still lack the flexibility to support a remote or hybrid workforce at scale. 2. **Personal/Mobile VPN:** Companies such as ExpressVPN and NordVPN offer downloadable VPN apps so users can keep data secure on their personal devices. This is a good measure to have in place if you’re browsing the web on insecure Wi-Fi networks. Some free VPNs are available to help keep your devices secure, but they’ll later become paid. 3. [**Remote access VPN**](https://cms.zscaler.com/resources/security-terms-glossary/what-is-remote-access-vpn)**:** These VPNs are designed specifically for users working from outside of the office in a corporate setting. They’re typically deployed within a company’s data center but can be extended (at the cost of web and/or app performance) to protect remote users from malware and other threats. These became extremely common after the onset of the COVID-19 pandemic. [Read more](/zpedia/what-is-a-vpn). ### Question: Benefits of Using a VPN ### Answer: VPNs can simplify security for a business or even an individual. At their core, they're designed to: - **Limit permissions.** Imagine if anyone could gain access to any network. VPNs overcome this by requiring users to authenticate their way into the network. - **Prevent throttling.** A VPN’s encrypted tunnel prevents visibility from the outside, so in theory, bandwidth remains wider and speeds stay fast. - **Secure devices.** Remote desktops as well as devices running Android and iOS operating systems can be protected with the help of a VPN. [Read more](/zpedia/what-is-a-vpn). ### Question: Challenges of Using a VPN ### Answer: Despite the promise of these benefits, however, VPNs come with their share of hindrances that can create headaches for IT departments or even increase risk. VPNs: - **Put users on the network.** VPNs inherently give employees and third parties direct access to the corporate network. The moment a user tunnels into the network via VPN, they are viewed as “trusted” without knowing whether they have earned sufficient trust and are granted [lateral access](https://cms.zscaler.com/zpedia/what-is-lateral-movement). - **Increase costs and complexity.** The cost of a full VPN gateway appliance stack becomes more expensive as latency and capacity limitations require organizations to replicate the stacks at each of their data centers. - **Aren’t built to scale.** VPNs are, by their nature, hardware-based. They’re not built to grow and scale to protect users, workloads, and applications as an organization’s needs increase. What’s more, hybrid work is now the norm, and most VPNs weren’t built to handle much outside of a corporate office or a limited number of employees working remotely. [Read more](/zpedia/what-is-a-vpn). ### Question: Business VPN Limitations ### Answer: Much of the trouble with traditional network security lies in inefficient and insecure VPN infrastructure, because: - **VPNs cannot prevent lateral threat movement.** Even though VPNs can keep data secure through encrypted tunnels on a smaller scale, they do not prevent further access to an organization’s network at large [if an endpoint has been compromised](https://cms.zscaler.com/resources/security-terms-glossary/what-is-endpoint-security). - **VPNs don’t scale well.** Hardware-based VPNs need to be manually configured, and their bandwidth caps tend to necessitate redundant deployments. Software-based VPNs need to be deployed on every user device, limiting the ways users can work. - **VPNs don’t do zero trust.** After authentication through a VPN, a user is on the network. From there, a hacker or malicious insider can move laterally to access sensitive information or exploit vulnerabilities that aren’t protected from the inside. Even the best VPNs aren’t able to secure all online activity, as some of their encryption protocols may not be able to stand up to today’s advanced threats. [Read more](/zpedia/what-is-a-vpn). ### Question: A VPN Alternative ### Answer: As organizations get accustomed to hybrid workforce models and cloud adoption becomes the norm, it becomes clearer that an old-fashioned firewall approach is too slow for the cloud and zero trust. Instead, you need a modern, digital-first solution tailored for the era of the cloud and mobility—a[ cloud-based security solution](https://cms.zscaler.com/platform/zero-trust-exchange) that decouples security from the network, with policies enforced anywhere apps reside and everywhere users connect. Moving security off the network and into the cloud effectively places the full [network security](https://cms.zscaler.com/resources/security-terms-glossary/what-is-network-security) stack everywhere your users go. Protections are applied consistently, offering the exact same security measures in branch offices, users’ homes, airport terminals, or corporate headquarters. Compared to traditional network security, the ideal cloud-based security solution provides: - **Faster user experience:** User traffic takes the shortest path to any app or internet destination. - **Superior security:** All internet traffic, including encrypted traffic, is inspected, with threat data correlated in real time. - **Reduced costs:** The need to constantly buy and maintain appliances disappears because cloud infrastructure is continually updated. - **Easier management:** A solution delivered as a service reduces the complexity of managing multiple devices.

These entry points range from phishing emails that deceive individuals, to software vulnerabilities that enable intruders to skirt normal security safeguards. Every potential avenue for attack significantly increases the security risk to organizations, highlighting why such an understanding is paramount in today's evolving, digital-first world. ### Question: Lifecycle of an Attack Vector ### Answer: - **Identification of vulnerability:** Attackers scout target environments, searching for a software vulnerability, misconfigured system, or other gap in defenses. - **Exploitation:** Once a weak point is found, the attacker employs various techniques—like [phishing](/resources/security-terms-glossary/what-is-phishing) attacks or direct code injection—to infiltrate the environment. - **Impact delivery:** The attacker takes advantage of the compromised system, potentially distributing [malware](/resources/security-terms-glossary/what-is-malware) or launching a [ransomware](/resources/security-terms-glossary/what-are-ransomware-attacks) campaign that disrupts operations. ### Question: Types of Attack Vectors ### Answer: When organizations contemplate what is an attack vector, they should keep in mind that it comes in many shapes and forms, each presenting unique obstacles and demands. Let’s take a closer look at some prominent types of attack vectors across modern-day organizations. - **Endpoint attack vectors:** Desktop computers, mobile devices, and IoT gadgets all constitute endpoints that connect to corporate networks. Here, usernames and passwords can be stolen, or strong passwords might be absent altogether. An unpatched operating system presents a prime target for cyberattack vectors, allowing attackers to plant [zero day vulnerabilities](/zpedia/what-is-a-zero-day-vulnerability) or other malicious files that linger until triggered. - **Network attack vectors:** These focus on intercepting data traversing through the organization’s internal or external networks. Attackers often capitalize on misconfigured firewalls, insecure Wi-Fi connections, or outdated protocols. A single flaw in network configurations can open the floodgates to gaining unauthorized access and attacking multiple segments of an organization’s infrastructure. - **Cloud-based attack vectors:** With today’s shift to cloud environments, new threat surfaces have emerged that can be much harder to secure. Misconfigurations in storage buckets, an absence of [multifactor authentication (MFA)](/zpedia/what-is-multifactor-authentication-mfa), and insufficient logging practices can leave cloud-based systems dangerously exposed. Compromise in these settings is vast, as successful takeover of a central console can yield sweeping control across virtual machines, applications, and databases. Modern enterprises also face an ever-evolving interplay between humans and technology in the context of cyberattacks. Below are two primary categories of vectors that each demand particular attention: **Human-Driven Vectors** - **Phishing:** Attackers masquerade as reputable entities, sending emails to trick recipients into revealing sensitive details or installing malware. - **Social engineering:** From phone calls to text messages, scammers exploit human emotions and trust to manipulate employees, continuously monitor responses, and glean insider information. - [**Insider threats:**](/zpedia/what-are-insider-threats) Disgruntled or careless insiders represent threats from within, potentially using their legitimate permissions to leak or sabotage data. **Technological Vectors** - **Malware:** Viruses, trojans, and worms undermine security by damaging files, observing keystrokes, or creating backdoors for persistent intrusion. - **Ransomware:** Attackers encrypt an organization’s data or systems, then demand payment to restore functionality. - **Zero day vulnerabilities:** Flaws within software or hardware that are unknown to the vendor, giving attackers the perfect opportunity to exploit these weaknesses before any patches are released. ### Question: What Is an Attack Surface? ### Answer: An attack surface is the total sum of all entry points—digital and physical—that an attacker can probe or exploit to break into a system. Essentially, it includes everything from infrastructure components and network interfaces all the way down to individual workflows and processes. When the question arises, “What is an attack surface?”, the answer points directly to the sum of possible attack vectors plus the underlying technologies, user activities, and configurations enabling potential breaches. In simpler terms, the broader your surface, the more likely that malicious actors can discover at least one weak link in the chain. This may manifest through outdated security controls, an unpatched server, or an inattentive user who clicks on every link in their inbox. Reducing this surface area is crucial for cybersecurity best practices, as it lessens the number of open doors intruders can walk through. In many ways, an attack surface shapes the scope of potential damage. Every unchecked web endpoint or insufficiently guarded device extends an invitation to adversaries. An overly complicated system lacking robust security measures is a prime environment for infiltration—especially if security teams don’t keep up with rigorous audits and thorough patching of vulnerabilities. Guarding your attack surface, therefore, requires a layered approach targeting both known and emerging threats, while embedding security intrinsically into the broader organizational culture. ### Question: Attack Vector vs. Vulnerability ### Answer: | **Comparison** | **Attack Vector** | **Vulnerability** | |---|---|---| | **Definition** | The route or method used to infiltrate a system. | A flaw or weakness that can be exploited by an attacker. | | **Role** | Acts as the means of delivering a threat. | Serves as the underlying risk factor in an application or protocol. | | **Example** | Phishing, network sniffing, malicious website links. | Outdated software, misconfigured servers, inadequate access controls. | | **Focus** | How the attacker gets in. | Where the system’s defenses are compromised. | | **Prevention Approach** | Blocking intrusion attempts at all external and internal checkpoints. | Identifying and patching weaknesses, training staff, and enforcing policy. | ### Question: Common Challenges in Mitigating Attack Vectors ### Answer: Securing a company’s digital footprint can be complex, especially when threats constantly evolve.

Consider the following: - **Regular assessments and patching:** Schedule ongoing reviews of software versions, configurations, and network layouts; apply fixes promptly to reduce exploiting vulnerabilities. - **Implement multifactor authentication (MFA):** Multifactor authentication drastically reduces the risk of unauthorized logins by adding layers of verification beyond just usernames and passwords. - **Establish strong user education:** Educate employees on safe online behavior, recognizing phishing emails, and flagging anomalies in real time. - **Segment and harden environments:** Partition networks, enforce access limitations, and monitor traffic meticulously to quarantine potential breaches before they spread. ### Question: The Role of Zero Trust in Mitigating Attack Vectors ### Answer: [Zero trust](/resources/security-terms-glossary/what-is-zero-trust-architecture) is a transformative strategy that focuses on validating every user and device before granting access, continuously verifying identity throughout each session. Instead of granting blanket permissions based on location or IP range, [zero trust](/resources/security-terms-glossary/what-is-zero-trust) ensures that every single connection is subject to scrupulous checks, dynamic policy enforcement, and real time monitoring. Such thorough oversight significantly diminishes attack vector success rates because it verifies each attempt to connect or retrieve data. Beyond warding off direct infiltration, zero trust works seamlessly alongside cybersecurity best practices by making each segment of your infrastructure a protected zone in its own right. This approach fundamentally changes how organizations think about security: Instead of a single fortress wall around the perimeter, each room within the castle is locked too, which makes preventing attack vectors more realistic. By overseeing all traffic and demands for access—whether internal or external—zero trust stops suspicious requests in their tracks, even if malicious actors have already compromised one part of the network. ### Title: What is an Intrusion Prevention System (IPS)? | Zscaler ### Description: Discover how an intrusion prevention system (IPS) detects, blocks, and prevents cyberthreats as well as types and benefits. ### URL: https://www.zscaler.com/zpedia/what-is-an-intrusion-prevention-system-ips ### Question: What Is an Intrusion Prevention System (IPS)? ### Answer: An intrusion prevention system (IPS) is a proactive security tool designed to detect, analyze, and block malicious activities before they disrupt computer networks. By continuously monitoring network traffic, it bolsters threat prevention, limiting suspicious activity and defending strategic points to reduce data breaches. ### Question: How Does an Intrusion Prevention System (IPS) Work? ### Answer: An IPS operates at critical junctions within your network—often called strategic points—where it scans the ceaseless flow of data for suspicious activity.

Learn why this is important, the limitations, and how it works ### URL: https://www.zscaler.com/zpedia/what-is-endpoint-detection-response-edr ### Question: What Is Endpoint Detection and Response (EDR)? ### Answer: Endpoint detection and response (EDR) is designed to protect endpoint devices from cyberthreats like ransomware, fileless malware, and more. The most effective EDR solutions continuously monitor and detect suspicious activities in real time while providing investigation, threat hunting, triage, and remediation capabilities. ### Question: How Does EDR Work? ### Answer: EDR works by continuously monitoring endpoints for suspicious activity, collecting and analyzing data, and providing real-time notifications of potential [threats](/learn/threats-and-vulnerabilities). Using behavioral analysis, machine learning, threat intelligence feeds, and more, EDR identifies anomalies in endpoint behavior and detects malicious activity, including things basic antivirus will miss, such as fileless malware attacks. ### Question: What are Key Functions and Capabilities of EDR? ### Answer: EDR capabilities vary from one solution to another, but the essential building blocks of EDR include: - **Real-time endpoint monitoring, visibility, and activity logging:** EDR continuously monitors endpoints for suspicious activity, collecting and analyzing endpoint data to enable organizations to quickly detect and respond to potential threats. - **Advanced threat detection with integrated threat intelligence:** Fueled by artificial intelligence and machine learning, EDR uses advanced techniques and threat intelligence feeds to identify potential threats—even previously unknown ones—and raise alerts. - **Faster investigation and incident response:** EDR tools and processes simplify management as well as automate alerts and response to help organizations take action during security incidents, including quarantine and remediation of infected endpoints. - **Managed detection and response (MDR):** Some providers offer EDR as a managed service, combining the advantages of EDR with a team of on-call experts. MDR is a potent option for organizations without the staff or budget for a dedicated internal SOC team. ### Question: Why Is EDR Important? ### Answer: With today’s attack surfaces widening and so many ways for attackers to get inside a network, an effective cybersecurity strategy must account for every threat vector. Let’s take a closer look: - **EDR provides visibility and remediation insight beyond basic security** like [firewalls](/products-and-solutions/cloud-firewall) and antivirus software, enabling an organization to better understand the nature of incidents, their root causes, and how to effectively address them. - **EDR offers real-time monitoring and detection, including behavioral analysis**, enabling an organization to root out evasive attackers and address zero day vulnerabilities before they escalate—reducing the risk of downtime, data loss, and follow-up breaches. - **EDR uses AI and machine learning to parse integrated threat intelligence feeds**, producing insight into attackers’ latest threats, methods, and behaviors so organizations can stay a step ahead in safeguarding their data. - **EDR saves time and money while reducing the risk of human error** by offering centralized management and reporting functions, machine learning-driven threat insights, automated response, and more for efficient, effective security operations. ### Question: What Should You Look for in an EDR Solution? ### Answer: The essence of effective EDR security is improved endpoint protection that eases your team's operational burdens. Ideally, it can accomplish this while also helping you reduce costs. You'll want to look for EDR that offers: - **Real-time visibility with behavior analytics:** Stop threats before they become data breaches with a real-time view of activities and behaviors on endpoints, going beyond basic signature and indicator of compromise (IOC) monitoring that overlooks novel techniques. - **Rich endpoint telemetry and threat intel:** Continuously improve your protection with endpoint telemetry and integrated threat intelligence feeds, giving your EDR tools and security team the valuable insight and context they need for effective threat response. - **Fast, accurate response and remediation:** Look for an EDR solution that leverages intelligent automation to take decisive, rapid steps against endpoint threats, stopping them before they can harm your data, your end users, or your business. - **The flexibility, scale, and speed of the cloud:** Eliminate downtime with automatic updates, keep endpoints secure regardless of their location, reduce your reliance on hardware, and lower your total cost of ownership compared to on-premises solutions. ### Question: What Are the Limitations of EDR? ### Answer: Many cyberthreats begin on endpoints, so effectively protecting them is crucial to secure your workloads, users, and the rest of your network. However, it’s important to recognize some of the limitations of EDR: - **EDR focuses on endpoints only.** Attacks often originate at the endpoint when end users download malicious files, but conventional EDR is blind to many types of attacks, including those on unmanaged endpoints (e.g., IoT and BYOD), cloud applications, servers, and supply chains. - **EDR may not be fast enough for today’s rapid attacks.** Passthrough sandboxes and “detection-first” approaches can allow malicious files and threat actors to access resources before the threats are detected. This limits their effectiveness against sophisticated threats such as LockBit ransomware, which can encrypt 100,000 files in under six minutes. - **EDR lacks visibility into how attacks move through your network and apps.** Because they collect data only from endpoints, EDR tools may lack broader context that can lead to more false positives. Gaining comprehensive visibility requires an extended detection and response (XDR) solution. ### Question: What’s the Difference Between EDR and XDR? ### Answer: You can think of XDR as an evolution of EDR that pairs broad-scope data collection as well as threat detection and response solutions with security orchestration. By collecting telemetry from your entire ecosystem—endpoints, clouds, networks, threat intelligence feeds, and more—XDR enables security analysts to conduct faster and more accurate detection, correlation, threat hunting, and incident response than EDR alone. ### Question: What’s the Difference Between EPP and EDR? ### Answer: Endpoint protection platforms (EPP) and endpoint detection and response (EDR) are both endpoint security solutions. Generally speaking, the difference between them is that EPP works to stop threats from reaching an endpoint, whereas EDR works to counteract threats that have already reached an endpoint. In this way, EPP and EDR could be considered the first and second lines of defense, respectively. ### Question: What's the Difference Between an Endpoint and EDR? ### Answer: Endpoints are devices that are connected to and communicate with a network, such as smartphones, IoT devices, desktop and laptop computers, and servers. EDR tools exist to counteract threats that make their way through a network's defenses and onto endpoints. You could think of an endpoint as a body and EDR as its immune system. ### Question: What's the Difference Between EDR and SIEM? ### Answer: EDR and security information and event management (SIEM) are distinct security tools. EDR focuses on monitoring and responding to threats on endpoints, leveraging endpoint-specific data and behavioral analysis. SIEM, meanwhile, aggregates and correlates data from various sources across an organization's IT ecosystem, providing a centralized view of security events to support threat analysis. Both EDR and SIEM can extend their functionality to cloud-based environments. ### Question: Is EDR a Firewall or Replacement for Antivirus? ### Answer: EDR is generally a complement to antivirus and firewall solutions, not a replacement for them, because EDR and firewall/AV have different core functionality. Basically, firewalls and antivirus are there to keep threats out of the network, whereas EDR is there to fend off threats that have already gained access to the network. Some EDR solutions also include antivirus functionality, which remains an effective measure against known threats. ### Question: Can EDR secure IoT and mobile devices? ### Answer: Yes, Endpoint Detection and Response (EDR) can secure IoT and mobile devices, though its effectiveness depends on the feature set of the solution and how it’s implemented. Below are key ways EDR can protect these devices: - Threat Detection and Prevention - Endpoint Visibility - Device Management - Integration with Broader Security Frameworks ### Question: What types of threats does EDR detect and block? ### Answer: Endpoint Detection and Response (EDR) is designed to detect, analyze, and block a wide range of cybersecurity threats targeting endpoints such as desktops, servers, mobile devices, and IoT systems.

Let’s take a look at some of the typical measures that contribute to overall IoT security. ### Question: Types of IoT Security ### Answer: You can think of IoT security in a few separate buckets: - **Device security measures** protect devices against cyberattacks by ensuring secure boot procedures; secure firmware updates, including vulnerability patching; and the use of secure communication protocols (e.g., TLS/SSL). Many device security measures also require device management, where an organization’s IT department administers maintenance, updates, and monitoring of devices. - **Network security measures** include firewalls, which block unauthorized access to devices and networks; VPNs, which encrypt data as it traverses the internet between a user and a data center; intrusion prevention systems (IPS), which detect and prevent cyberattacks; and DDoS security, which thwarts[ distributed denial of service](/resources/security-terms-glossary/what-is-a-denial-of-service-attack) attacks. - **Cloud security measures** include secure data storage, access controls, and encryption. Many IoT devices store data they collect in the cloud, so strong security, encryption, and authentication are crucial to keep that data where it belongs. One more measure not specific to IoT security—but nonetheless key to securing IoT devices—is strong identity and access management, ensuring only authorized users and other devices can access IoT data. ### Question: Top Challenges of IoT Security ### Answer: As one of the big enablers of digital transformation, IoT devices have seen rapid, broad adoption worldwide. Unfortunately, they tend to create some significant security challenges by nature. IoT device security has a reputation for being poor, with many devices offering little in the way of their own protection. There are a few reasons for this: - **Memory and processing power limitations** in many devices make security measures like firewalls and encryption difficult to implement.¹ - **Weak factory-default login credentials** are common and can be trivial for attackers to crack—a major vulnerability if it’s overlooked. - **Lack of vendor support for older devices** can cause firmware and software to fall behind on important security updates, and patching the devices is often difficult. - **Lack of standardization across devices**, a common issue with new technologies, can make it difficult for a single security solution to protect all IoT. Beyond the security of the devices themselves, IoT devices can contribute to broader security and operational challenges for an organization, such as: - **A large number of new attack vectors** as the devices communicate with your network, the cloud, and each other. - **Scaling issues around the influx of data** from IoT devices, which can overtax existing IT and security infrastructure. - **Privacy concerns around data collection**, particularly of personal data and intellectual property—especially if it’s not fully clear what data is collected or how it’s used. ### Question: IoT Security Best Practices ### Answer: To keep your sensitive data and applications safe from threats, it’s critical to enact access policies that keep IoT devices from serving as an open door. Keep these best practices in mind: - **Track and manage network devices.** If your organization allows unmanaged IoT devices, you can’t rely on endpoint agents alone to gain complete visibility. Deploy a solution that can identify devices communicating across your network, understand their functions, and inspect encrypted communications that might otherwise slip past your defenses. - **Change default passwords.** Factory-default credentials make it extremely easy for attackers to exploit devices. You may not be able to control passwords on unsanctioned IoT devices, but for managed IoT, this is a basic first step. It should also be part of your security training for any devices employees bring to work. - **Stay on top of patching and updates.** Many industries—particularly manufacturing and healthcare—rely on IoT devices for day-to-day workflows. For these sanctioned devices, stay up to date on newly discovered vulnerabilities and keep your device security current. - **Implement a zero trust security architecture.** Eliminate implicit trust policies and tightly control access to sensitive data with dynamic, identity-based authentication. Inspect traffic to and from all unsanctioned IoT devices that require internet access, and block them from all corporate data through a proxy. Zero trust is the only effective way to stop unsanctioned IoT devices from posing a threat to your network. ### Question: What Is IoT Privacy and Security? ### Answer: IoT privacy and security is anything to do with protecting personal data collected by IoT devices from unauthorized access, use, and disclosure, as well as securing the devices against attacks and malicious access.

Discover more. ### URL: https://www.zscaler.com/zpedia/what-is-lateral-movement ### Question: What Is Lateral Movement? ### Answer: Lateral movement is a set of techniques cybercriminals use to access other devices, apps, or assets on a network after they first compromise an endpoint. Using stolen login credentials or other methods of privilege escalation, threat actors move through the network as they close in on sensitive data. With their activities disguised as permitted network traffic, attackers can avoid detection and prolong their attacks. [Read more](/zpedia/what-is-lateral-movement). ### Question: How Does Lateral Movement Happen? ### Answer: A threat actor can perform lateral movement after compromising an endpoint connected to a network that lacks adequate access controls. They might achieve this through credential abuse, exploiting a vulnerability in a server or application, leveraging malware to create a backdoor, and various other methods. Many conventional network security measures won’t detect malicious activity because it appears to be coming from legitimate users. [Read more](/zpedia/what-is-lateral-movement). ### Question: Stages of Lateral Movement ### Answer: A lateral movement attack occurs in three main steps: 1. **Reconnaissance:** The threat actor explores the network. As they develop understanding of naming conventions and network hierarchies, identify open firewall ports, and pinpoint other weaknesses, the actor can formulate a plan for getting deeper inside the network. 2. **Infiltration**: Using login credentials often obtained through phishing attacks or other social engineering, the actor employs credential dumping and privilege escalation techniques to gain access to different parts of the system. 3. **Access:** Once the actor locates the target system or data, they can begin their attack in earnest—delivering a malware payload, exfiltrating or destroying data, or various other possible ends. [Read more](/zpedia/what-is-lateral-movement). ### Question: What Types of Attacks Use Lateral Movement? ### Answer: Most types of attacks include, or can include, lateral movement techniques, including ransomware attacks and other malware, phishing, and others. Once they have established a foothold in a network, attackers can use that position as a base from which to conduct further attacks. Using techniques such as hijacking and spear phishing, attackers can move across the network as if they were a legitimate user without alerting conventional cybersecurity measures to their presence. [Read more](/zpedia/what-is-lateral-movement). ### Question: Examples of Lateral Movement in Cyberattacks ### Answer: - **Pass the hash (PtH):** Rather than using a plaintext password for authentication, an attacker inputs a stolen password hash—the same encrypted string stored in the authenticator—and is granted access. - **Pass the ticket (PtT):** An attacker uses stolen tickets from the default Windows authentication protocol, Kerberos, to authenticate without needing to know the user’s password. - **Exploitation of remote services:** Once inside a system, an attacker can take advantage of vulnerabilities or misconfigured permissions in connected remote services to gain access to other parts of the network. - **Internal spear phishing:** An attacker who already has access to a legitimate user’s account can use spear phishing attacks to obtain shared credentials, access codes, and the like. Targets who think they know who they’re talking to are less likely to suspect foul play. - **SSH hijacking:** Attackers can hijack connections made through Secure Shell (SSH), a common remote access protocol in macOS and Linux, to bypass authentication and gain access to another system through the encrypted SSH tunnel. - **Windows admin shares:** Most Windows systems enable admin shares by default. If a threat actor gains administrative access, admin shares can enable them to quickly move laterally by exploiting their permissions to manage and access other hosts. [Read more](/zpedia/what-is-lateral-movement). ### Question: Steps for Preventing Lateral Movement ### Answer: On the one hand, you need to stop lateral movement before it happens. To do that: - **Use effective, modern endpoint security.** Hybrid work is here to stay, and to keep workers secure and productive, you need endpoint and mobility solutions that enable end-to-end [zero trust](/resources/security-terms-glossary/what-is-zero-trust) access control, threat detection, and response across a wide variety of devices. - **Protect high-value targets.** Compromising an account with administrative privileges gives an attacker access to your most valuable and sensitive data. Protect these accounts with the highest levels of security, and reserve their use for only the tasks that require the highest privileges. - **Implement microsegmentation.** [Microsegmentation](/zpedia/what-is-microsegmentation) creates secure zones that allow you to isolate workloads from one another and secure them individually. Granular segments can be tailored to the needs of different traffic, creating controls that limit network and application flows between workloads to those that are explicitly permitted. - **Maintain a security-first zero trust approach.** Everyone at your organization—not just IT or a small security team—should take responsibility for security. Ensuring all staff understand and adhere to common security protocols, and taking a [zero trust](/resources/security-terms-glossary/what-is-zero-trust) approach to security, will reduce your risk of cyberattacks more than anything else. [Read more](/zpedia/what-is-lateral-movement). ### Question: Steps for Detect Lateral Movement ### Answer: - **Monitor login activity.** Keeping a close eye on authentication traffic may allow you to detect direct compromises and credential theft before attackers can do damage. - **Run behavior analytics.** Machine learning-powered analysis can establish a baseline of normal user behavior and flag deviations that could signify a cyberattack. - **Use deception technology.** Realistic decoy assets deployed in your network act as lures for cybercriminals. Unable to differentiate the fake from the real, attackers raise a silent alarm the moment they interact with a decoy. - **Employ threat hunting:** Taking a proactive approach to identifying previously unknown or ongoing threats in your network, expert threat hunting—through a managed service, for most organizations—is a powerful defense against advanced, stealthy attacks. [Read more](/zpedia/what-is-lateral-movement). ### Question: Prevent and Control Lateral Movement with Zero Trust ### Answer: Taking advantage of trust—not just the sort conferred by authentication, but also the sort conferred by human nature—is one of the oldest tricks attackers know. It persists today as one of the most effective ways they can position themselves to move laterally in your environment. To deny them that opportunity, you need to take trust out of the equation. A zero trust architecture enforces access policies based on context—including the user's role and location, their device, and the data they are requesting—to block inappropriate access and lateral movement throughout your environment. Zero trust requires visibility and control over your environment's users and traffic, including that which is encrypted; monitoring and verification of traffic between parts of the environment; and strong multifactor authentication (MFA) methods beyond passwords. Critically, in a zero trust architecture, a resource's network location isn't the biggest factor in its security posture anymore. Instead of rigid [network segmentation](/resources/security-terms-glossary/what-is-network-segmentation), your data, workflows, services, and such are protected by software-defined microsegmentation, enabling you to keep them secure anywhere.

By uniquely identifying each resource (e.g., server, application, host, user), your organization can configure permissions that provide fine-grained control of data traffic. When implemented using zero trust principles, microsegmentation enables you to stop lateral movement of threats, prevent workload compromise, and stop data breaches. [Read more](/zpedia/what-is-microsegmentation). ### Question: Microsegmentation vs. Network Segmentation ### Answer: | ## **Microsegmentation** | ## **Network Segmentation** | |---|---| | Microsegmentation, on the other hand, is best used for east-west traffic, or traffic that moves across the data center or cloud network—server-to-server, application-to-server, and so on. Simply put, network segmentation is like a castle’s outer walls and moat, whereas microsegmentation is like the guards standing at each of the castle’s interior doors. | [Network segmentation](/resources/security-terms-glossary/what-is-network-segmentation) is best used for north-south traffic (i.e., the traffic that moves into and out of the network). With network segmentation, an entity, such as a user, is trusted once inside a designated zone of the network. | ### Question: Microsegmentation Features ### Answer: Some of the technical benefits of microsegmentation include: 1. ### **Centralized security controls and management across networks** 2. ### **Segmentation policies that adapt automatically** 3. ### **Gap-free protection** [Read more](/zpedia/what-is-microsegmentation). ### Question: Business Benefits of Microsegmentation ### Answer: - ### **Proactive network and IT security** Microsegmentation removes security roadblocks common with traditional segmentation by creating application-aware policies that travel with all apps and services. As a result, potential data breaches are contained to affected assets, not the entire network. Some microsegmentation services even offer functionality that leverages automation to identify all communicating software, recommend zero trust policies, and let you apply them with one click. - ### **Reduced vulnerability** Instead of static controls that rely on IP addresses, ports, and protocols, teams can cryptographically fingerprint each workload to provide consistent protection to workloads operating in an internal data center or the cloud. Fingerprinting decouples your workload security from IP address constructs to avoid issues with IP-based controls. - ### **Continuous risk assessment** Microsegmentation lets you quantify risk exposure by automatically measuring the visible network attack surface to understand how many possible application communication pathways are in use. Some services even verify the identities of communicating software each time software requests a communication, which mitigates risk, supports regulatory compliance mandates, and provides visualized risk reports. [Read more](/zpedia/what-is-microsegmentation). ### Question: What is Zero Trust Segmentation? ### Answer: A [zero trust](/resources/security-terms-glossary/what-is-zero-trust) security model is based on principles of microsegmentation. Policy is applied to workloads, not network segments, allowing you to close off all trust to any resource at any location for which you can’t establish sufficient context. In a zero-trust model, for example - particularly one that's cloud-based - a company could determine that medical devices can only interact with other medical devices. [Read more](/zpedia/what-is-microsegmentation). ### Question: What Is a Workload? ### Answer: A workload is a set of processes, tasks, or resources related to an application’s operation, such as communication, processing, and management. In the cloud, workloads include the applications themselves. Managing workloads helps identify vulnerabilities, secure data, control access, apply encryption, and monitor and reduce threats. ### Question: What Is an Example of Microsegmentation? ### Answer: As a simple example of microsegmentation, a company could microsegment workloads deployed inside a VPC/VNet to isolate critical assets like databases and servers. If a hacker compromises a user endpoint, they are limited to that one segment, protecting sensitive data and core infrastructure from further access. ### Question: Why Do We Need Microsegmentation? ### Answer: Organizations need microsegmentation to protect data and critical resources as networks become more complex. It limits lateral movement, reduces the attack surface, and isolates breaches. With the rise of remote work, IoT, and cloud reliance, microsegmentation strengthens security where traditional perimeter defenses fail. ### Question: Which Industries Benefit Most from Microsegmentation? ### Answer: Industries handling sensitive data or critical infrastructure, such as healthcare, finance, government, and e-commerce, see the greatest benefits from microsegmentation. It helps improve security, maintain data integrity, and meet regulations like HIPAA or GDPR. However, businesses of any size or sector can improve security and reduce risk with this approach. ### Question: Will Microsegmentation Reduce Costs? ### Answer: Microsegmentation can lower capex and opex. It minimizes financial losses from data breaches, reduces downtime, and increases operational efficiency. It can also decrease hardware costs, reliance on point products, and administrative time by streamlining network security and management. ### Question: Why Is Getting Microsegmentation Right Key to Zero Trust? ### Answer: Microsegmentation enforces least-privileged access, a core requirement of zero trust. It blocks lateral movement by verifying each connection before allowing access, reducing the attack surface. This approach strengthens zero trust defenses, which are far more effective than perimeter-based models for protecting modern IT environments. ### Title: What Is Mobile Threat Defense (MTD)?

Benefits & Challenges ### Description: Discover multifactor authentication's (MFA), a security mechanism requiring users to verify their identity, robust protection, why it is critical, and more. ### URL: https://www.zscaler.com/zpedia/what-is-multifactor-authentication-mfa ### Question: What Is Multifactor Authentication (MFA)? ### Answer: Multifactor authentication (MFA) is a security mechanism requiring users to verify their identity through two or more independent factors before gaining access to a system or resource. These factors typically include something the user knows (like passwords), something they have (like a hardware token), or something they are (like a fingerprint or facial recognition). MFA strengthens access control by adding multiple layers of security, making it significantly harder for attackers to breach accounts or systems through stolen credentials alone. ### Question: How does MFA work? ### Answer: MFA operates by requiring users to authenticate their identity using multiple forms of evidence before granting access. Each factor falls into one of three categories: knowledge (e.g., passwords or PINs), possession (e.g., smartphones, security keys, or hardware tokens), and inherence (e.g., biometric data like fingerprints or facial recognition). By combining factors from at least two of these categories, MFA ensures a higher level of identity verification than traditional single-factor authentication methods. ### Question: What are the key benefits of MFA? ### Answer: MFA provides robust protection against unauthorized access. Here are four key benefits: - **Enhanced security:** By requiring multiple factors, MFA significantly reduces the risk of credential-based attacks like [phishing](/resources/security-terms-glossary/what-is-phishing), brute force, or credential stuffing. - **Protection against identity theft:** MFA safeguards sensitive data by adding layers of securithttps://www.zscaler.com/resources/security-terms-glossary/what-is-phishingy, ensuring that usernames and passwords alone are insufficient for attackers to breach accounts. - **Improved regulatory compliance:** Many industries require MFA to comply with regulations like GDPR, HIPAA, and PCI DSS, helping enterprises meet security standards. - **Streamlined user experience:** Modern MFA solutions, such as push notifications or biometric authentication, simplify the login process while maintaining high security. ### Question: What are the challenges of using multifactor authentication? ### Answer: While MFA is a critical security measure, it does present some challenges: - **User friction:** Some users find MFA inconvenient, especially when required to use hardware tokens or repeatedly enter OTPs. - **Implementation complexity:** Integrating MFA with legacy systems or custom applications can be technically challenging and resource-intensive. - **Device dependence:** Many MFA methods rely on smartphones or hardware tokens, which can be lost, stolen, or inaccessible in certain situations. - **Cost overhead:** Deploying and maintaining a robust MFA solution can be costly, particularly for small and medium-sized businesses. To mitigate these challenges, IT teams can adopt user-friendly authentication methods, ensure thorough training, and deploy [centralized identity management](/blogs/product-insights/introducing-zidentity-migrating-admins-centralized-identity-experience) systems to streamline MFA implementation. ### Question: Why is MFA Is Important for Enterprises? ### Answer: As the threat landscape evolves, enterprises are increasingly targeted by cyberattacks, including credential theft, [ransomware](/resources/security-terms-glossary/what-is-ransomware), and phishing. MFA plays a vital role in enterprise security by providing an additional layer of protection beyond traditional usernames and passwords, which are often exploited by attackers. By requiring multiple authentication factors, MFA ensures that even if an attacker gains access to one factor, such as a compromised password, they cannot bypass the system without additional verification. This makes it significantly harder for attackers to breach sensitive enterprise systems, protecting valuable assets and data. MFA also reinforces authentication and authorization processes, ensuring only authenticated users can access critical resources. ### Question: What is the difference between MFA and two-factor authentication (2FA)? ### Answer: While multifactor authentication (MFA) and two-factor authentication (2FA) are closely related, they are not the same. Here’s a comparison: - **MFA** - Requires two or more independent factors. A core component of zero trust frameworks. - **2FA** - Requires exactly two factors. May not fully align with zero trust. Both MFA and 2FA strengthen authentication, but MFA, with its ability to incorporate multiple layers of security, integrates more seamlessly with [zero trust](/resources/security-terms-glossary/what-is-zero-trust) principles. ### Question: Why Does Zero Trust Matters with MFA? ### Answer: Zero trust is a cybersecurity approach based on the principle of "never trust, always verify." It assumes that no user or device, whether inside or outside the network, should be trusted by default.

Definition & Types Explained ### Description: Social engineering is the art of manipulating human emotion and trust to gain unauthorized access to information or systems in various ways. Read more. ### URL: https://www.zscaler.com/zpedia/what-is-social-engineering ### Question: What Is Social Engineering? ### Answer: Social engineering is the art of manipulating human emotion and trust to gain unauthorized access to information or systems. Whether through phone calls, text messages, phishing campaigns, or face-to-face requests, social engineering attackers exploit human-based cyberthreats by creating deceptive scenarios that “look and feel” genuine. By presenting a convincing front, they persuade unsuspecting individuals to act in ways that compromise security. ### Question: How Does Social Engineering Work? ### Answer: Social engineering capitalizes on human vulnerabilities rather than software defects, with attackers crafting their methods around behavioral patterns. Once the [bad actors](/zpedia/what-is-a-threat-actor) identify a target—be it an individual or organization—[they gather bits of information](/zpedia/what-is-pretexting) like phone numbers, email addresses, or even details from social media to learn about their target’s habits and relationships. ### Question: What are the Steps of a Social Engineering Attack? ### Answer: 1. **Surveillance and research:** Attackers gather background information (e.g., social media updates, email addresses) to learn about their target’s habits and network. 2. **Initial contact and rapport:** The social engineer masquerades as a trusted figure—perhaps a colleague or authority—to establish credibility and build comfort. 3. **Manipulation and request:** Having won some trust, the attacker requests sensitive details or actions—like clicking a link—under the guise of urgency or legitimacy. 4. **Escalation and exploitation:** Once the victim complies, attackers may install [malware](/resources/security-terms-glossary/what-is-malware), steal more data, or continue accessing the compromised system unimpeded. ### Question: What are Types of Social Engineering Attacks? ### Answer: Below are five examples of the types of social engineering in the current landscape: - [**Phishing scams:**](/resources/security-terms-glossary/what-is-phishing) Attackers send fraudulent emails or messages that appear legitimate, often prompting victims to click a deceiving link or divulge personal data. These messages are frequently branded to imitate trusted institutions, such as banks or tech firms. - [**Vishing:**](/zpedia/what-is-vishing) Vishing, or voice phishing, is a form of social engineering where cybercriminals use voice calls to impersonate trusted individuals or organizations to trick victims into revealing sensitive information, such as passwords or financial details. - [**Business email compromise (BEC):**](/cxorevolutionaries/insights/understanding-and-preventing-business-email-compromise) Cybercriminals impersonate high-level executives or business partners in order to request wire transfers or sensitive documents under the guise of urgency. The unsuspecting employee, wanting to please a boss or a VIP client, often complies without hesitation. - **Water holing:** Attackers identify websites frequented by a specific group (e.g., employees of a certain organization) and infect them with malware. By compromising a site that the target trusts, criminals can lure them into downloading harmful software in a place where they feel safe. - **Human impersonation:** This method sees an attacker pose as a trusted insider or authority figure—such as tech support staff or a government official. Faced with uniformed questions, a victim might reveal a social security number or other private information to “verify identity.” ### Question: Who are Common Targets of Social Engineering ### Answer: - **Healthcare staff:** Individuals working in hospitals and clinics have immense access to medical records, often containing social security numbers and personal histories. Attackers view them as a goldmine due to the sensitive, life-altering nature of that data. - **Financial personnel:** Employees in banking or accounting departments are desirable prey for social engineering attacks, as they hold important financial credentials that can be leveraged for fraud or direct theft. - **Administrative assistants:** Admins manage schedules, expense records, and a host of other details that could provide a gateway into deeper organizational secrets. They’re often seen as the “front line” for executives, making them prime targets for infiltration attempts. - **High-value executive roles:** C-level staff, board members, or directors wield power over vital corporate information. When criminals gain their trust, they can potentially authorize significant fund transfers or leak proprietary documents. - **Third-party vendors/contractors:** External partners with system access or sensitive data are targeted due to often weaker security, providing a pathway into the main organization. ### Question: What are Real-World Examples of Social Engineering? ### Answer: Below are some social engineering examples from real incidents: - **Voice deepfake fraud (Vishing):** [Attackers used an advanced audio tool](https://westoahu.hawaii.edu/cyber/forensics-weekly-executive-summmaries/euler-hermes-group-deepfake-forensic-analysis/) to impersonate a high-level executive’s voice in a phone call, compelling an employee to transfer funds to a fraudulent account under the false assumption of executive approval. - [**Smishing**](/zpedia/what-is-smishing-sms-phishing) **campaign:** [Malicious text messages](https://www.lansingstatejournal.com/story/news/local/michigan/2025/04/17/toll-scam-text-michigan-smishing-mdot-benson/83136195007/) are being sent out imitating departments of transportation, parking authorities, etc., usually specific to a particular US state, asking targets to pay unpaid tolls. - [**Spear phishing**](/resources/security-terms-glossary/what-is-spear-phishing) **in cryptocurrency:** [Cybercriminals targeted a popular crypto-exchange](https://www.cryptopolitan.com/binance-users-targeted-in-sms-phishing-scam/) by emailing employees and tricking them into downloading software that contained hidden malware. This infiltration led to identity theft of customer records. ### Question: What Impact does Social Engineering Attacks have on Compliance and Regulatory? ### Answer: Social engineering attacks can lead to severe legal ramifications for organizations that fail to adequately protect stakeholder data.

For instance, did a [threat](/learn/threats-and-vulnerabilities) feed provide new intel specific to an emerging malware strain, such as signature data? Did the organization notice a sudden spike in outbound traffic? - **Lead-driven threat hunting** **(a.k.a. structured hunting)** is hypothesis-driven or based on specific IOCs that guide the investigation. - **Leadless threat hunting (a.k.a. unstructured hunting)** doesn't depend on specific leads or indicators. ### Question: What are the Benefits of Automation in Cyberthreat Hunting? ### Answer: Automation is essential to effective threat hunting, paired with human lateral thinking and creativity. Malicious actors will exploit any advantage they can, which today means they’re increasingly using artificial intelligence and automation to fuel their attacks. In other words, it’s a classic example of fighting fire with fire. ### Question: What are the most effective threat hunting models and methodologies? ### Answer: Various threat hunting models and methodologies help hunters identify, investigate, and mitigate threats with a focus on different aspects, based on what suits the nature of their team or the threat itself. Some common models are: - **MITRE ATT&CK Framework** - **Lockheed Martin Cyber Kill Chain** - **Cyber Threat Intelligence Life Cycle** - **Observe, Orient, Decide, Act (OODA) Loop** - **Diamond Model of Intrusion Analysis** ### Question: What are the best threat hunting tools available? ### Answer: Just as there are many hunting methodologies, there are many tools in the cyberthreat hunter’s toolkit. Some of the common technologies: - **Security information and event management (SIEM)** - **Network traffic analysis (NTA)** - [**Endpoint detection and response (EDR)**](/zpedia/what-is-endpoint-detection-response-edr) - **Threat intelligence platforms (TIPs)** - **Security orchestration, automation, and response (SOAR)** - **Vulnerability scanning** - **Attack surface management (ASM)** - [**Malware sandboxes**](/products-and-solutions/cloud-sandbox) - **Threat emulation and Red-Teaming** - [**Deception technology**](/resources/security-terms-glossary/what-is-deception-technology) ### Question: Who Should Be Involved in Threat Hunting? ### Answer: Security analysts versed in threat detection and hunting tools are the most essential players in your threat hunting efforts, taking the lead in monitoring and analyzing alerts, tracking suspicious behaviors, identifying indicators of attack (IOAs), and more. Smaller organizations may only employ a single full-time analyst, while larger ones may have sizable security operations center (SOC) teams or managed services. ### Question: What Do You Need to Start Hunting Threats? ### Answer: Your organization needs four key things to hunt threats effectively: 1. **A team of skilled hunters and analysts.** If you have an in-house security team, invest in ongoing training and development to help them protect your organization against evolving, sophisticated threats. 2. **The right mix of threat hunting technologies and automated tools**, including SIEM platforms, EDR solutions, NTA tools, and threat intelligence platforms. 3. **Access to logs, network traffic data, behavior data**, and more to ensure your threat hunters have a complete view of the threat landscape. 4. **A clear strategic framework for threat hunting**, with defined objectives and strategies that align with your risk tolerance and security posture. ### Question: What Is Proactive Threat Hunting? ### Answer: Proactive threat hunting is the process of actively rooting out threats hiding in an organization's network before they can become attacks and cause harm. It combines human expertise with ML-driven anomaly detection and analysis to uncover suspicious activities that traditional security tends to miss. ### Question: What's the Difference Between Threat Hunting and Threat Intelligence? ### Answer: Threat hunting is to threat intelligence what carpentry is to a hammer: one is a process, and the other a tool. Threat intelligence is data—on emerging trends, known threats, and more—that analysts and security solutions can interpret to understand threats and contextualize risks. Threat hunting puts threat intel into practice as analysts search in real time for hidden threats. ### Question: When Should You Do Threat Hunting? ### Answer: Effective enterprise security strategies include threat hunting as an integral ongoing component. Regular threat hunting exercises, even when your organization isn’t under a clear threat, can help identify hidden threats and vulnerabilities in your environment. Consistent threat hunting efforts strengthen your organization’s security posture against both known and unknown threats. ### Question: Where Should You Hunt for Threats? ### Answer: Threats are becoming more numerous and sophisticated. Thus, amid today’s modern, distributed networks and cloud workloads, no corner of the IT environment is safe for threat hunters to ignore. Threat hunting should extend to all layers of the network, all IT assets (endpoints, servers, clouds, critical apps, etc.), and all user activities. ### Question: How Does Extended Storage Help with Threat Hunting? ### Answer: Extended storage helps you retain larger amounts of historical data and logs, providing a larger dataset to help your threat hunters correlate and examine historical patterns, anomalies, and IOCs that might have been overlooked before. This, in turn, helps them identify persistent threats that may have previously gone undetected. ### Title: What Is Threat Intelligence?

[Read more](/zpedia/what-is-url-filtering). ### Question: Why Is URL Filtering Important? ### Answer: URL filtering is a key element of web security that allows an organization to configure how users access webpages through the network or other systems. It can help to: - **Protect users and data from security threats** such as phishing sites, ransomware, and other malware - **Rein in bandwidth usage and lost productivity** due to use of non-work-related sites or apps - **Limit the organization’s exposure to liability** by blocking access to inappropriate content [Read more](/zpedia/what-is-url-filtering). ### Question: What Is a URL? ### Answer: A Uniform Resource Locator, or URL, is an address that corresponds to the location of a website, database, web application, or protocol (among other things), allowing a web browser to retrieve it. [Read more](/zpedia/what-is-url-filtering). ### Question: How Does URL Filtering Work? ### Answer: URL filtering works by applying granular policies that allow or restrict access to particular URLs. Policies can be based on multiple criteria, such as URL categories, specific users or user groups, departments, locations, and time intervals. When an end user tries to access any URL, the request is compared in real time against active URL filtering policies to determine whether the request is allowed. If access is granted, the page loads normally. If access is denied, the page is prevented from loading, and the user is instead shown a block notification. [Read more](/zpedia/what-is-url-filtering). ### Question: Key Features of URL Filtering ### Answer: Basic URL filtering solutions allow administrators to customize simple allow and/or block lists to block access to undesired or malicious URLs. Today’s advanced URL filtering tools include these features and more, allowing you to configure: - **Granular, modular policies:** Effective URL filtering policies can be molded to suit the needs and restrictions of multiple groups across an organization. For example, an HR team might need unrestricted access to LinkedIn, but an IT team might not. - **“Allow” and “block” actions:** The basic “green light” and “red light” actions of URL filtering permit or deny access according to policy. - **“Caution” action:** Unlike a block, this action informs a user of potential security risks associated with a request and allows the user to decide whether or not to proceed. - **“Override” action:** Generally reserved for advanced or administrative users, the option to override enables a “block” rule to be bypassed altogether. - **Duration and bandwidth quotas:** Administrators can specify limits on bandwidth consumed and browsing time, after which the action for that URL will change to a more restrictive one (i.e., “caution” or “block”).

Read this article to learn more. ### URL: https://www.zscaler.com/zpedia/what-is-vishing ### Question: What Is Vishing? ### Answer: Vishing, or voice phishing, is a form of social engineering where cybercriminals use voice calls to impersonate trusted individuals or organizations to trick victims into revealing sensitive information, such as passwords or financial details. ### Question: How Does Vishing Work? ### Answer: Vishing attacks are becoming increasingly sophisticated, leveraging both technology and social engineering to exploit human vulnerabilities. Below are some of the most common techniques and tactics used by cybercriminals to carry out vishing attacks: - Caller ID Spoofing - Pretexting - VoIP Exploitation - Interactive Voice Response (IVR) Attacks ### Question: How is artificial intelligence used to enhance phishing scams? ### Answer: [Artificial intelligence (AI)](/zpedia/what-generative-ai-cybersecurity) is increasingly being weaponized in the world of cyberattacks, enabling more sophisticated techniques that can deceive even the most vigilant users. When it comes to [phishing](/resources/security-terms-glossary/what-is-phishing), AI amplifies attackers' ability to scale, personalize, and manipulate their targets, making vishing more dangerous than ever before. Some techniques include: - **Voice Cloning -** Cybercriminals can now replicate the voice of a trusted individual, such as a company executive or family member, by using just a few minutes of recorded audio. - **Deepfake Video Calls -** AI can also create deepfake video calls where attackers impersonate someone in real time. These video-based vishing attacks are especially effective in remote work environments. - **Robocalls -** Using natural language processing (NLP), these calls can respond intelligently to victims' input, making the interaction feel more authentic. - **AI Data Mining for Targeted Vishing -** AI can sift through vast amounts of publicly available data, such as social media profiles, company websites, and leaked databases, to create highly targeted vishing attacks. ### Question: Why Is Vishing a Growing Threat? ### Answer: Vishing is seeing more and more use due to the increasing sophistication of cybercriminals as well as the widespread reliance on mobile communication. Attackers are leveraging advanced social engineering tactics to exploit human vulnerability, often bypassing traditional security measures. With people more connected than ever, especially with the rise of remote work, fraudsters are finding new opportunities to manipulate individuals into revealing sensitive information over the phone. ### Question: What are some real-world examples of vishing attacks? ### Answer: 1. South Korea has experienced a surge in vishing attacks, including a case in August 2022 where a doctor lost $3 million in cash, insurance, stocks, and cryptocurrency to criminals. 2. A[ finance employee in Hong Kong paid $25 million](https://www.cnn.com/2024/02/04/asia/deepfake-cfo-scam-hong-kong-intl-hnk/index.html) after a video call with deepfake ‘chief financial officer’ on a video conference call. The actor tricked the employee into attending a video call with who he thought were several other members of staff but were actually deepfake recreations. 3. In the summer of 2023, [attackers impersonated Zscaler’s own CEO, Jay Chaudhry](https://www.foxbusiness.com/video/6328691103112), in a vishing attack using AI technology. The attacker called a Zscaler employee on WhatsApp. ### Question: What are Common Vishing Scenarios? ### Answer: Vishing attacks come in many forms, each designed to exploit trust and convince victims to share sensitive information. Here are some of the most common tactics used by cybercriminals: - **Bank fraud scams:** Callers pose as bank representatives, claiming your account has been compromised. They pressure you into providing personal details or even transferring funds to a "secure" account. - **Tech support scams:** Fraudsters impersonate tech support from reputable companies, warning of malware on your device and requesting remote access to "fix" the issue, which is actually a ploy to steal data or install malicious software. - **IRS/tax scams:** Attackers claim to be from the IRS or tax authorities, threatening arrest or legal action unless you pay an outstanding tax bill—often via untraceable methods like gift cards or wire transfers. - **CEO fraud (Business email compromise):** Cybercriminals target employees by impersonating senior executives, instructing them to make urgent wire transfers or disclose confidential company information, often under the guise of a time-sensitive emergency. ### Question: What is the difference between Vishing vs. Phishing vs. Smishing? ### Answer: While all three—vishing, phishing, and smishing—are forms of social engineering attacks designed to manipulate victims into divulging sensitive information, they differ primarily in their delivery methods and the specific tactics used to exploit human trust. - **Phishing**: typically involves fraudulent emails that impersonate legitimate entities, such as businesses, government agencies, or trusted individuals. The goal of phishing attacks is usually to steal login credentials, financial information, or other sensitive data. - **Smishing:** like phishing emails, smishing messages often appear to come from trusted sources—such as banks, delivery services, or even coworkers—and typically include a malicious link or prompt to share sensitive details. - **Vishing:** vishing uses voice communication, typically via phone calls, to manipulate victims. Attackers may impersonate, whether through text or AI voice cloning technology, authority figures such as tax officials, tech support representatives, or even family members in distress. ### Question: How do You Protect Yourself and Your Organization from Vishing? ### Answer: Vishing attacks are growing in sophistication, but there are clear steps your organization can take to mitigate the risk. Implementing the right strategies can help safeguard both personal and corporate information from voice-based phishing threats, including: - Security Awareness Training - Caller Authentication Procedures - Use of Anti-Spam Technology - Incident Response Plans - AI Security and Threat Intelligence ### Question: How can a layered Zero Trust approach protect against vishing attacks? ### Answer: This paradigm shift requires a multi-layered defense strategy that integrates AI-powered monitoring, continuous authentication, and [endpoint protection](/resources/security-terms-glossary/what-is-endpoint-security).

Verify the caller’s identity independently, avoid sharing personal details, and be wary of unsolicited calls claiming to represent trusted institutions. ### Question: What Should I Do if I Encounter a Vishing Attack? ### Answer: If you receive a suspicious call, hang up immediately. Avoid sharing sensitive information, report the incident to your IT or security team, and consider using AI-powered threat detection tools to prevent similar attacks in the future. ### Title: What Is Vulnerability Management? Best Practices & Challenges ### Description: Vulnerability management is the systematic approach of identifying, assessing, and monitoring cybersecurity vulnerabilities across an company’s infrastructure. ### URL: https://www.zscaler.com/zpedia/what-is-vulnerability-management ### Question: What is the Vulnerability Management Lifecycle? ### Answer: Every successful vulnerability management process follows a cyclical chain of steps designed to help organizations keep their environments secure. These steps are dynamic and adapt to the evolving threat landscape: 1. **Asset discovery and assessment:** First, teams perform asset discovery to maintain a comprehensive view of every asset–including endpoints, IT/OT/IoT assets, cloud resources, applications, and services on their network. Without a real-time inventory, potential security gaps can remain undetected. Assets should also be evaluated for multiplying risk factors such as misconfigurations, risky open ports, unauthorized software, or missing security controls (i.e., EDR agents). 2. **Vulnerability identification:** Using vulnerability scanners and automated tools, IT and security teams detect and catalog security vulnerabilities that exist in assets. This step lays the groundwork for understanding potential exploits and risk to the organization.. 3. **Risk evaluation and prioritization:** Once vulnerabilities are identified, a risk-based vulnerability management (RBVM) strategy looks at the severity of each finding (including exploitability and known threat actors) along with the criticality of affected systems. This ensures that teams tackle the most pressing risks first. 4. **Remediation and mitigation:** Patching, configuration changes, and other security controls form the remediation arsenal. If immediate patch management is not possible, organizations apply mitigations or compensating controls to reduce the risk without leaving the door wide open. 5. **Verification and reporting:** Lastly, teams verify fixes and generate reports to demonstrate compliance and progress. This final documentation helps drive continuous monitoring efforts and validates that identified vulnerabilities have been properly resolved. ### Question: What Is Vulnerability Management? ### Answer: Vulnerability management is the systematic approach of identifying, assessing, and monitoring cybersecurity vulnerabilities across an organization’s infrastructure. By regularly scanning networks and applications, teams proactively minimize risks, thwart unauthorized access, and reduce the likelihood of disruptive data breaches. ### Question: What tools are used in Vulnerability Management? ### Answer: Organizations rely on specialized solutions to efficiently detect and remediate security vulnerabilities. These tools automate lengthy processes, helping teams focus on proactive strategies while reducing human error: - [**Cyber asset attack surface management (CAASM):**](/zpedia/what-is-cyber-asset-attack-surface-management-caasm) The success of every vulnerability management program is contingent on complete visibility and understanding of their asset environment. CAASM tools (ideally with built-in External Attack Surface Management) provide a continuously updated inventory for the security program. - **Vulnerability scanners:** Widely used for vulnerability assessment, these scanning tools systematically probe systems looking for known security flaws, missing software updates, and weak access controls. - **Risk assessment platforms:** Advanced dashboards categorize findings, correlate them with real-world exploits, and surface the most urgent issues. They guide teams in performing thorough risk assessments and prioritizing remediation tasks. - **Penetration testing frameworks:** Although more manual than simple scanners, penetration testing software simulates real-world attacks to reveal hidden weaknesses. This is vital for validating defenses and highlighting business-critical security gaps. - **Automated tools for patch management:** These solutions streamline software updates across diverse environments, removing the grunt work of manually applying fixes. They also maintain a digital paper trail for compliance audits. ### Question: What are the key best practices for effective vulnerability management? ### Answer: Maintaining a robust program requires a combination of strategic thinking, technology integration, and continuous improvement. By adhering to these principles, organizations can better safeguard their intellectual property and customer data: - **Risk-based prioritization:** Understand that not all discovered vulnerabilities pose equal threats. Focus resources on those with the highest potential impact and likelihood of exploitation. - **Continuous scanning and monitoring:** [Threat actors](/zpedia/what-is-a-threat-actor) never stop hunting for weaknesses. Frequent vulnerability scanning helps detect changed conditions and newly disclosed risks before they spiral out of control. - **DevSecOps integration:** Incorporate security tasks within the software development lifecycle. Automated tests, code reviews, and vulnerability management tools should be introduced as early as possible to “shift left.” - **Cross-functional collaboration:** Nurture open communication between IT, security, development, and leadership. When teams share knowledge and align on goals, they can respond swiftly to emerging threats. - **Governance and policy alignment:** Ground vulnerability management in well-defined policies that stand up to audit scrutiny. Clearly documented standards guide teams to fulfill regulatory requirements and foster consistent decision-making. ### Question: What are the common challenges in vulnerability management? ### Answer: Despite its importance, vulnerability management faces hurdles in both technical and organizational realms. Addressing the following pitfalls helps maintain an effective and proactive security posture: - **Volume of vulnerabilities:** Hundreds or thousands of issues can surface in a single scan. Traditional vulnerability management tools often struggle to provide accurate context and prioritization, leaving security teams to slog through endless lists of detections with limited understanding of business risk. - **Asset visibility issues:** Without continuous asset discovery, it’s difficult to track every server, application, and device—particularly in a dynamic technology environment. The modern attack surface includes rapid development in the cloud, complex internet exposures from legacy systems and services, and even vulnerabilities in GenAI and LLMs. Threat actors are counting on blind spots amidst the complexity. - **Limited remediation bandwidth:** The best vulnerability management solution is only as good as its ability to mobilize a response to critical risk. [CISA guidance](https://www.cisa.gov/sites/default/files/publications/CISAInsights-Cyber-RemediateVulnerabilitiesforInternetAccessibleSystems_S508C.pdf) calls for remediation of internet-facing systems within 15 days of discovering a vulnerability. It is imperative for a successful VM program to prioritize quickly and streamline patch deployment across security and IT teams to stay ahead of adversaries.. - **Patch testing delays:** Even with robust patch management, organizations need to test software updates to prevent business outages. This process can hold up critical remediation efforts, making it even more critical to prioritize patches for truly critical business risk. - [**Zero day vulnerabilities:**](/zpedia/what-is-a-zero-day-vulnerability) Newly-discovered and celebrity vulnerabilities carry varying degrees of risk, so security teams need an effective way to assess exploitability and quickly map to impacted assets. In some cases such as [Log4Shell](https://www.csoonline.com/article/571797/the-apache-log4j-vulnerabilities-a-timeline.html), a zero-day outbreak represents a critical threat. Teams must often deploy mitigating controls for critical exposures while they wait for a patch from vendors. - **Siloed teams and poor communication:** Fragmented departments slow down the vulnerability management process. When responsibilities aren’t shared, the effort to keep networks secure becomes scattered and less effective. ### Question: What are the latest trends in vulnerability management? ### Answer: Keeping pace with rapid technological changes calls for innovation in how organizations handle vulnerability scanning, assessment, and remediation. These emerging areas help streamline programs and counteract increasingly sophisticated threats: - **Threat Intelligence Integration:** Gathering data from external sources refines vulnerability prioritization. - **AI/ML for predictive scoring:** [Artificial intelligence (AI)](https://m/zpedia/what-is-artificial-intelligence-ai-in-cybersecurity) and machine learning technology can analyze vast sets of vulnerability data, uncovering patterns that point to security risk. - **Cloud native and container environments:** Modern infrastructures revolve around containers, microservices, and distributed deployments. - **Attack surface management (ASM):** [ASM](/zpedia/what-is-external-attack-surface-management) goes beyond conventional scanning by continuously mapping all publicly exposed assets to understand potential entry points. - **Managed vulnerability management (VMaaS):** Some organizations choose a managed vulnerability management tool suite, allowing third-party experts to handle frequent scans, reports, and remediation guidance. ### Question: How is AI impacting vulnerability management practices? ### Answer: [Artificial intelligence (AI)](/zpedia/what-is-artificial-intelligence-ai-in-cybersecurity) and machine learning technology can analyze vast sets of vulnerability data, uncovering patterns that point to security risk. Predictive scoring helps identify high-impact flaws even before they’re widely known. As models learn from historical attacks, they empower teams to reduce the risk of future incursions. ### Question: How does vulnerability management align with regulatory compliance requirements? ### Answer: Vulnerability management plays a vital role within various compliance frameworks, including NIST 800-53, PCI DSS, HIPAA, and SOC 2. Organizations must demonstrate that they have processes for identifying security vulnerabilities, performing rigorous risk assessments, and applying timely remediation steps. In this regard, the ability to produce evidence of vulnerability scanning activities, patch deployments, and mitigating actions becomes crucial for proving adherence to regulatory mandates. It’s not just about checking boxes during audits—robust vulnerability management fosters real resilience against emerging [cyberthreats](/resources/security-terms-glossary/what-is-cyberthreat-protection). Effective vulnerability management also improves audit readiness by generating the documentation needed for third-party reviews and SLA reporting. When organizations can prove that they use systematic scanning methods, apply essential security controls, and verify remediation efforts, they position themselves as responsible stewards of crucial assets. Having a documented vulnerability management plan in place also strengthens incident response and business continuity efforts. If a [breach](/zpedia/what-data-breach) or security event does occur, a well-maintained remediation history demonstrates preparedness and aids in swift recovery. Meanwhile, ongoing oversight of potential weak points promotes a culture of proactive risk governance that minimizes disruptions and preserves trust among stakeholders. ### Question: What Are the Differences Between a Vulnerability, a Risk, and a Threat? ### Answer: A **vulnerability** is a weakness in a system, a **threat** is something that can exploit that weakness, and **risk** is the potential damage when a threat targets a vulnerability. Each plays a distinct role in cybersecurity. ### Question: What’s the Difference Between a Vulnerability Assessment and Vulnerability Management? ### Answer: A vulnerability assessment is a one-time scan or audit that identifies potential weaknesses, while vulnerability management is an ongoing process that includes assessment, remediation, tracking, and reporting over time. ### Question: How Often Should Vulnerability Scans Be Performed? ### Answer: Best practices recommend conducting vulnerability scans at least weekly or monthly, depending on asset sensitivity. For high-risk environments or cloud native workloads, continuous vulnerability scanning is ideal (multiple times per day). ### Title: What Is Extended Detection and Response (XDR)? | Zscaler ### Description: XDR (extended detection and response) is a category of cybersecurity solutions that combines previously disconnected threat detection and response tools. ### URL: https://www.zscaler.com/zpedia/what-is-xdr ### Question: What Is XDR? ### Answer: Extended detection and response (XDR) is a category of cybersecurity solutions that pairs previously disconnected threat detection and response tools with security orchestration. By collecting telemetry from an organization’s entire ecosystem—including endpoints, clouds, networks, threat intelligence feeds, and more—XDR enables faster and more accurate detection, correlation, threat hunting, and incident response than endpoint detection and response (EDR) alone. [Read more](/zpedia/what-is-xdr). ### Question: How Does XDR Work? ### Answer: XDR continuously performs three core functions: ### 1. Analysis The solution collects data across servers, endpoints, clouds, and other parts of the ecosystem, correlates that data, and sends only relevant, important alerts to the organization’s security team, helping to minimize alert fatigue. ### 2. Detection Taking advantage of its wide and deep visibility, XDR uses ML to establish a baseline of normal user and entity behavior. Layered with other detection mechanisms, this allows the XDR solution to investigate anomalies that could indicate security threats. ### 3. Response XDR isolates and eliminates a threat, and then updates security policies to stop that threat in the future. Where it goes beyond EDR is in consolidating security operations center (SOC) resources across network, endpoint, and cloud environments in one console. [Read more](/zpedia/what-is-xdr). ### Question: Benefits of XDR Security ### Answer: An effective XDR platform provides: 1. **Broad, deep visibility and insights:** With perspective that extends beyond the endpoint, an XDR solution can understand sophisticated threats—including point of entry, affected assets and environments, and methods—across any port, protocol, or layer of your ecosystem, giving you an edge in remediation and root cause analysis. 2. **Automated correlation and triage:** ML-driven automation correlates data and prioritizes alerts, optimizing your security team’s remediation workflows by helping them avoid false positives and surface true threats in volumes of data they could never parse with manual security solutions. 3. **Faster, more efficient operations:** With a holistic, centralized view of threats, fewer security tools to manage and monitor, and automated analysis, XDR reduces operational complexity and frees up your experts for proactive threat hunting and other valuable tasks. [Read more](/zpedia/what-is-xdr). ### Question: XDR Use Cases ### Answer: XDR supports three primary use cases: - ### Triage With the sheer volume of threats targeting today’s enterprise networks, even the most skilled security professionals can’t keep up with the alerts, let alone quickly and accurately sort out the false positives, prioritize the most critical threats, and respond. XDR uses ML and advanced analytics to refine threat data from the entire ecosystem into a manageable number of high-quality alerts. - ### Threat Hunting Today’s sophisticated threats are extremely good at hiding, making threat hunting both more important and more difficult than ever. Because XDR offers visibility into your entire ecosystem alongside ML-powered detection and correlation, it can pinpoint threats that traditional SIEM solutions alone will miss. - ### Investigation XDR solutions provide rich context to support root cause analysis, including real-time and historical data, helping your security team understand what happened in an attack and what it will take to stop similar attacks in the future. [Read more](/zpedia/what-is-xdr). ### Question: Key XDR Requirements ### Answer: At its core, XDR is: - **SaaS-based:** Fundamentally, XDR is delivered as a cloud service. This offers strong returns in terms of the cost of hosting and maintaining it, but it’s also key to how XDR delivers effective protection, since updates can be delivered instantly to all customers. - **Agent-based:** Although XDR is based in the cloud, it still requires an agent installed on your physical and virtual endpoints to gather data, performing the duties of a SIEM. Many agents also perform antivirus and other endpoint protection functions that complement the SaaS functionality. - **Unified:** This is the essence of XDR. By gathering telemetry from any data source and using that to fuel behavior analytics, advanced detection techniques, XDR offers protection from ransomware and other advanced malware well beyond what disconnected point products can do. [Read more](/zpedia/what-is-xdr). ### Question: How Does XDR Support Zero Trust? ### Answer: If your organization is looking to implement [zero trust](/resources/security-terms-glossary/what-is-zero-trust)—or hone your existing zero trust architecture—you’d do well to add XDR to your cloud-delivered security stack to take full advantage of: - **Streamlined cloud security:** Deploying zero trust in a multicloud environment can present some challenges. XDR streamlines much of the process by consolidating cloud workloads across environments and supporting comprehensive monitoring. - **Better visibility:** XDR performs real-time analysis and centralized security analytics across your environment, making it easier for your organization to deploy and enforce zero trust security controls. - **Automation:** XDR automates key tasks across identification, triage, hunting, and response, reducing the burden on your security team. AI- and ML-based analysis of user and network behavior helps deliver faster and more efficient security. - **Prioritization:** Zero trust assumes anything might be a threat until proven otherwise. XDR fits perfectly here: using automated correlation and ML-powered analytics to avoid overwhelming security teams with alerts, it helps optimize workflows and reduce response times.

It also monitors ongoing behavior to ensure policies are enforced at all times. ZTAA establishes a highly secure environment where resources require explicit proof of legitimacy, resulting in a more resilient and adaptable security posture. ### Question: What Is Zero Trust? ### Answer: [Zero trust](/resources/security-terms-glossary/what-is-zero-trust) is a security model that challenges the idea of inherently trusted network perimeters and instead demands persistent verification of trust for every connection, privilege request, and movement within an organization. Traditional strategies often assumed that being inside a company’s firewall equates to implicit trust, but modern environments are too dynamic for such assumptions. Today’s zero trust security model adopts a “trust always verify” ethos, which means that authenticated users must continually prove they have the right to access sensitive information. By requiring scrutiny at every step and limiting [lateral movement](/zpedia/what-is-lateral-movement), zero trust helps reduce the risk of [breaches](/zpedia/what-data-breach) in a perimeterless, digital-first world. As threats evolve, businesses must adapt, and zero trust has emerged as the cornerstone of the modern security framework. Cybercriminals look for weaknesses that allow them to move from one compromised system to another, so locking down each segment of the infrastructure is essential. This is where the principles of zero trust come into play, ensuring no implicit trust is given to any device or entity, even if it is inside the corporate network. Combine this mentality with reliable security solutions, and organizations stand a much stronger chance of detecting and responding to malicious behavior promptly. In essence, zero trust helps create an environment where every access request is challenged, validated, and approved under rigorous scrutiny. ### Question: Where Does Zero Trust Application Access (ZTAA) Fit Into Zero Trust? ### Answer: A practical embodiment of zero trust can be found in ZTAA, which centers on secure application access to an organization’s infrastructure. By adopting core [zero trust architecture](/resources/security-terms-glossary/what-is-zero-trust-architecture) concepts, ZTAA grants application access based on precise contextual singals such as user identity, device posture, and behavioral patterns. These controls limit the scope of potential compromise by allowing only authenticated users to access authorized applications—never the entire network—thus shrinking the overall attack surface. Unlike legacy security models that trust entities once they pass a firewall checkpoint, ZTAA follows the trust model of continuously verifying identities and mandating the [principle of least privilege](/resources/security-terms-glossary/what-is-least-privilege-access). Traditional solutions often aimed to seal off network perimeters, but that concept no longer meets the demands of dispersed users and cloud-based applications. Instead, zero trust application access prevents unauthorized access by restricting each user to the specific resources needed, ensuring a “need-to-know access” standard is met and mitigating the danger of internal or external infiltration. ### Question: Core Components of ZTAA ### Answer: ZTAA typically comprises four key elements, each working together to create a cohesive security posture: - [**Identity and access management (IAM):**](/zpedia/what-is-identity-and-access-management) IAM solutions ensure users prove who they are when initiating any access request. This component enforces granular policies around identity, roles, and permissions. IAM can be broken down into two categories: - Identity providers (IdPs), e.g., Okta, Microsoft - Access management for app access, e.g., Zscaler - [**Endpoint security:**](/resources/security-terms-glossary/what-is-endpoint-security) Verifying device health is crucial to allow entry into an environment. Scanning endpoints for compliance and vulnerabilities strengthens the zero trust stance by ensuring only healthy devices gain access. - [**Microsegmentation:**](/zpedia/what-is-microsegmentation) By dividing the enterprise network into distinct segments, ZTAA prevents an attacker from gaining free rein. Even if one area is compromised, microsegmentation keeps other resources insulated and protected. - **Continuous monitoring and analytics:** Security teams must continuously monitor network traffic and user behavior to detect anomalies or suspicious behavior. These insights help in detecting and responding to potential threats before they escalate. ### Question: Benefits of ZTAA ### Answer: Embracing zero trust application access can provide a variety of advantages to businesses of all sizes, including: - **Enhanced security posture:** Because it limits access by verifying each connection, ZTAA drastically reduces threats tied to unvetted internal traffic. - **Reduced attack surface:** By focusing on per-application restrictions, attackers cannot navigate extensively inside the network; they simply have no route for lateral movement. - **Improved user experience and productivity:** ZTAA’s context-based approach allows seamless access to apps without cumbersome [VPNs](/zpedia/what-is-a-vpn) or blanket permits, streamlining the daily workflow. - **Scalability and flexibility:** As organizations adapt to hybrid and remote setups, ZTAA ensures that adding new users or endpoints is smooth, consistent, and uniformly governed by zero trust principles. ### Question: Common Challenges in Implementing ZTAA and How to Overcome Them ### Answer: Implementing ZTAA is not without obstacles; organizations can face technological and cultural barriers that hinder progress. Below are four prevalent challenges, along with recommendations for overcoming them: - **Complexity of legacy infrastructure:** Merging ZTAA with pre-existing systems can be daunting. To alleviate friction, catalog your current infrastructure and gradually phase in zero trust controls. - **User adoption and skepticism:** Employees may fear change, particularly if they assume it will hamper productivity. Communicating the value of secure application accessibility and delivering effective training can smooth the transition. - **Maintaining continuous verification:** Zero trust demands constant reevaluation of users and devices. Automated workflows paired with identity and access management capabilities help streamline repeated checks and limit disruptions. - **Visibility gaps in multicloud environments:** Sprawling architectures create blind spots for security model enforcement. Monitoring tools that unify activity logs across multiple clouds enable security teams to maintain a centralized view and respond efficiently. ### Question: Best Practices for Successful ZTAA Implementation ### Answer: A structured methodology helps ensure ZTAA works effectively across an entire organization. Below are four recommendations for a strong, well-rounded deployment: - **Draft a roadmap and phased rollout:** Pinpoint areas where zero trust application access will have the greatest immediate impact, then gradually expand coverage to additional apps and users. - **Integrate with robust identity solutions:** IAM is pivotal in a zero trust architecture, so ensure your organization invests in system interoperability and [multifactor authentication (MFA)](/zpedia/what-is-multifactor-authentication-mfa). - **Microsegment your environment:** Application access security hinges on preventing unauthorized lateral movement. By segmenting network resources based on role, purpose, and sensitivity, you effectively seal off each workload. - **Continuously monitor for anomalies:** Commit to proactive surveillance of user actions and data flows. Doing so helps identify suspicious behavior early, ensuring you can implement a zero trust stance that wards off or contains potential breaches. ### Title: What Is Zero Trust for the Department of Defense? | Zscaler ### Description: Zero trust for the Department of Defense is referring to zero trust security and how the DoD can benefit from zero trust enablement. ### URL: https://www.zscaler.com/zpedia/what-zero-trust-department-defense ### Question: What Is Zero Trust for the Department of Defense? ### Answer: Zero trust for the Department of Defense is a DoD information enterprise secured by a fully implemented, department-wide zero trust cybersecurity framework. The journey to zero trust requires all DoD Components to adopt and integrate zero trust capabilities, technologies, solutions, and processes across their architectures, systems, and within their budget and execution plans. In January 2022, the Department established the DoD Zero Trust Portfolio Management Office (ZT PfMO) within the DoD CIO to orchestrate the DoD efforts outlined in the DoD Zero Trust Strategy document and to accelerate ZT adoption through several courses of action. [Read more](/zpedia/what-zero-trust-department-defense). ### Title: What’s the Difference Between SDP and VPN? | Zpedia ### Description: This article covers the main differences between a software-defined perimeter (SDP) and a virtual private network (VPN). ### URL: https://www.zscaler.com/zpedia/what-s-difference-between-sdp-and-vpn ### Question: What is the difference between SDP and VPN? ### Answer: The difference between a software-defined perimeter (SDP) and a virtual private network (VPN) is that where a traditional VPN places a barrier around an entire corporate network, an SDP effectively negates a network perimeter by placing security policies and controls around software, reducing permissions to a workload-to-workload or app-to-app basis rather than a typical perimeter-based architecture. ### Question: Why is SDP considered more secure than VPN? ### Answer: SDP employs a "zero trust" security model, requiring strict authentication and authorization before granting access to individual resources. In contrast, VPNs often allow broad access to the network after initial authentication, which can increase vulnerability to lateral movement by malicious actors. ### Question: Can SDP replace VPN entirely? ### Answer: While SDP can replace VPN in many scenarios, especially for securing remote access and cloud infrastructure, some legacy systems or specific use cases may still rely on VPNs. SDP is well-suited for modern environments focused on zero trust principles. ### Question: Is SDP a VPN alternative? ### Answer: SDP is an alternative to VPN—in fact, it is a stark improvement over a VPN. Where a VPN is based on a risky network-centric approach, SDP is built on a user- and app-centric approach. An SDP enables secure access to private applications by establishing connectivity on a dynamic identity- and context-aware basis, which inherently reduces risk. ### Question: What can I use instead of a VPN? ### Answer: Many of today’s modern businesses are taking a software-defined approach to networking and security. Legacy castle-and-moat security models, such as a VPN, do not adequately protect remote and hybrid employees, so many businesses are turning to an SDP. Most SDPs come under the branding of zero trust, ZTNA, app segmentation, or other monikers. ### Question: How do SDPs relate to zero trust security? ### Answer: SDP and zero trust network access (ZTNA) are essentially one in the same. SDP relates more generally to the architecture, where ZTNA places a more memorable and digestible moniker to such an architecture. Companies can and will use either to describe a secure user- and app-centric transaction when it comes to access, but ZTNA, or zero trust, is much more commonly used today. ### Title: Why Cyber Risk Management Is Critical in Regulated Industries ### Description: Explore how a risk management plan ensures compliance, operational resilience, and data protection in regulated industries.

Strong data security is essential for safeguarding operations, maintaining customer trust, and ensuring compliance in today's digital-driven environments. [Read the full article on this topic](https://zpedia/what-is-data-security) **Why Traditional Data Security Models Are No Longer Enough** Traditional data security uses outdated assumptions and methods, including perimeter-based defenses, broad access controls, and implicit, system-level trust. These approaches worked when most data and users were in one physical location, but in today’s complex, distributed environments, they put sensitive data at risk. ### Question: What Is Zero Trust Data Security? ### Answer: Zero trust data security starts with a simple premise: never trust, always verify. In the zero trust model, every entity—user, device, app, or transaction—is treated like a potential threat until it is authenticated. [Read the full article on this topic](/zpedia/what-is-zero-trust-data-protection) **How Zero Trust Strengthens Data Security** Instead of defending the network perimeter, zero trust protects the data itself, whether on a device, in a cloud storage bucket, or flowing between endpoints. By inspecting data at every stage, zero trust ensures consistent protection. ### Question: Taditional Data Security vs. Zero Trust Data Security ### Answer: | **Category** | **Traditional Data Security** | **Zero Trust Data Security** | |---|---|---| | **Access to Sensitive Data** | Broad Access | Least-Privileged Access | | | Unrestricted access across systems, leading to excessive exposure and risks like insider threats, credential theft, lateral movement, and data loss. | Ensures users access only what they need, when they need it. Role-based permissions reduce exposure and minimize abuse or accidental leaks. | | **Security Approach** | Passive, Static | Dynamic, Active | | | Static rules rely on access controls, leaving data vulnerable to misuse, interception, and threats beyond the network perimeter. | Continuous verification based on user identity, behavior, and device posture protects data at rest and in transit across clouds, endpoints, and hybrid environments. | | **Visibility into Data Usage** | Poor Visibility | Deep Visibility | | | Incomplete visibility creates blind spots for unauthorized access and misuse, making detection of breaches or leaks difficult. | Continuous monitoring, logging, and analytics help identify unusual data access patterns early, such as large downloads at odd times. | | **Encrypted Traffic Inspection** | Limited Inspection | Real-Time Inspection | | | Encryption (e.g., TLS/SSL) protects data but creates blind spots as attackers use it to disguise their activities. Traditional tools struggle with large-scale encrypted traffic inspection. | Advanced tools inspect encrypted traffic in real time at massive scale, closing blind spots and identifying threats across cloud, endpoint, and network channels. | | **Trust Model** | Implicit Trust Inside the Perimeter | Trust Nothing by Default | | | Assumes trusted users will handle sensitive data responsibly, increasing risks of insider threats (both malicious and accidental). | Continuously verifies and restricts access based on behavior and intent to minimize insider threats. Suspicious actions trigger alerts or access revocation. | ### Question: Top Zero Trust Data Protection Use Cases ### Answer: **1. Control Data Access** **Problem:** Traditional systems rely on static credentials, like passwords, to grant broad access after users log in. These credentials are easy to steal, and excessive permissions create risks of accidental misuse or exposure of sensitive data. **Solution:** Zero trust enforces least-privileged access, giving users access only to the specific data they need. Permissions are limited and updated dynamically, and every access request is verified as it happens. [Multifactor authentiction (MFA)](/zpedia/what-is-multifactor-authentication-mfa) and identity-based controls stop attackers from exploiting stolen credentials, reducing the overall risk. **2. Manage Data Exposure** **Problem:** Traditional systems focus on network defense but often fail to secure data within the network. They lack tools to monitor or restrict how data is shared, allowing sensitive data to be exposed accidentally or exploited by attackers. **Solution:** Zero trust architecture encrypts data in transit, so unauthorized users can’t read or use it. It also applies [microsegmentation](/zpedia/what-is-microsegmentation) to limit visibility within the network. Unified control across apps and devices reduces data-sharing risks, even in cloud apps or email attachments. AI tools can identify sensitive data and flag exposure risks as they arise. **3. Prevent Lateral Movement** **Problem:** Once attackers breach a traditionally secured network, they can often move freely between systems. Poor segmentation and gaps in detection allow hackers to move from system to system to find and exploit high-value data. **Solution:** Zero trust prevents lateral movement by segmenting systems and enforcing verification at every step. Users cannot access systems outside their scope, so even if hackers breach one account or system, access to others is blocked. Microsegmentation limits the "blast radius" of attacks while continuous monitoring flags strange behavior, stopping threats before they can escalate. **4. Stop Double Extortion Ransomware** **Problem:** Traditional tools aim to keep ransomware off the network, but they often fail to protect data during attacks. Beyond the basic encrypt-and-extort strategy, [double extortion ransomware](/resources/security-terms-glossary/what-is-double-extortion-ransomware) encrypts files and exfiltrates the data for added leverage. **Solution:** Zero trust secures both access points and sensitive data. Encryption ensures stolen data remains useless to attackers. Microsegmentation and strong access controls limit ransomware from spreading or encrypting high-value assets. AI-powered monitoring identifies ransomware behaviors early and acts quickly to shut them down before damage escalates. ### Question: The Business Impact of Zero Trust Data Security ### Answer: Zero trust data security delivers meaningful benefits beyond reduced risk. Some of the ways zero trust can transform modern business operations include: **Improved Compliance** Zero trust protects sensitive data across all environments and provides continuous monitoring, ensuring adherence to regulations like GDPR, HIPAA, and CCPA.

Its streamlined approach replaces multiple security tools, saving time and money for businesses. **Increased Efficiency** Zero trust automates processes like threat response and access verification, reducing administrative workloads and improving efficiency. Unified policies simplify security management and ensure seamless protection across devices and environments. **Secure Hybrid and Remote Work** Zero trust safeguards sensitive data wherever it resides by inspecting encrypted traffic, managing dynamic permissions, and enforcing consistent protections across endpoints. This makes it ideal for remote work and BYOD policies. **Stronger Customer Trust** Organizations adopting zero trust show their commitment to protecting sensitive data, strengthening customer confidence and loyalty. This proactive approach also enhances their competitive position in data-driven industries. ### Question: What Problems Does Zero Trust Data Security Solve? ### Answer: Zero trust solves modern data security problems like unauthorized access, accidental exposure, lateral movement, and ransomware threats. It also simplifies compliance efforts by unifying security policies across apps, clouds, and devices. By focusing on continuous verification instead of static trust, it eliminates risks within distributed and cloud-heavy environments. ### Question: How Is Zero Trust Different from Traditional Data Security? ### Answer: Traditional data security relies on perimeter-based protection, giving users and systems inside the network broad access to resources. Zero trust takes a stricter approach, continuously verifying access and limiting permissions to data required for specific tasks. It focuses on protecting data directly, regardless of where it resides or flows, reducing exposure to breaches. ### Question: What Are the Benefits of Zero Trust Data Security? ### Answer: Zero trust improves data protection by limiting access with least-privilege policies, stopping unauthorized data sharing, preventing lateral threat movement, and reducing ransomware risks. It simplifies compliance and enables visibility into encrypted traffic. This protection extends across cloud apps, endpoints, and remote workflows, ensuring sensitive data stays secure everywhere. ### Title: Zero Trust vs. Traditional Security: The Future of Cybersecurity ### Description: Explore how zero trust security outperforms legacy models in tackling modern cyberthreats, protecting cloud-first organizations with continuous verification. ### URL: https://www.zscaler.com/zpedia/zero-trust-policy-vs-traditional-security ### Question: Zero Trust vs Traditional Security: What's the Difference? ### Answer: | **Aspect** | **Traditional Security** | **Zero Trust Model** | |---|---|---| | **Core Principle** | Based on implicit trust inside network perimeters. | "Never trust, always verify"—requires continuous contextual verification. | | **Focus** | Protects the network perimeter; assumes internal users/devices are trustworthy. | Decouples IT resource access from network access; no "trusted zones." | | **Tools Used** | Firewalls, Virtual Private Networks (VPNs), and other perimeter-based tools. | Cloud-delivered service with policies enforced at the edge, not centralized data centers. | | **Access Method** | Requires users to connect to the network where IT resources are housed. | Extends access directly to IT resources based on contextual data and risk. | | **Assumption of Trust** | Implicit trust for users, devices, and activities inside the network perimeter. | Continuous verification of all users, devices, and activities—no implicit trust. | | **Real-Time Monitoring** | Limited real-time activity monitoring tied to perimeter tools. | Comprehensive real-time activity monitoring, ensuring proactive responses to threats. | | **Challenges** | Struggles to adapt to cloud-first, hybrid work environments with dispersed users, devices, and data. | Designed for modern cloud environments and hybrid work scenarios; addresses today's threat landscape. | | **Delivery Method** | Typically centralized within on-premises data centers. | Delivered as a service from the cloud. | | **Relevance for Organizations** | Sufficient for traditional, on-premises operations but outdated for modern threats in cloud-based environments. | Essential for staying ahead of evolving cyberthreats in modern, distributed IT ecosystems. | ### Question: Why Traditional Security Models Are No Longer Enough? ### Answer: Traditional perimeter defenses, such as firewalls, fortify networks against attacks from outside while trusting users or devices inside. For anything to access anything else, both must be connected to the network.

These attacks impacted thousands of organizations worldwide and underscored the need for proactive threat protection. ### Question: How Are Zero Day Vulnerabilities Discovered? ### Answer: Zero day vulnerabilities are discovered through a variety of methods, including independent research by security researchers, bug bounty programs, or when actors exploit them for financial or political gain. The discovery process typically involves: - **Code analysis:** Reviewing software code to identify potential security flaws - **Penetration testing:** Simulating attacks to uncover weak points in a system - **Fuzz testing:** Using automated tools to input random data into applications to identify unexpected behaviors - **Reverse engineering:** Analyzing software or applications to identify exploitable vulnerabilities - [**Threat intelligence:**](/zpedia/what-is-threat-intelligence) Monitoring cyberthreats and malicious actor activity to detect potential zero day exploits ### Question: What is the difference between Zero Day Vulnerability vs. Zero Day Attack vs. Zero Day Exploit? ### Answer: While "zero day vulnerability," "zero day attack," and "zero day exploit" are often used interchangeably, they represent distinct aspects of a cybersecurity threat. Understanding these differences is crucial for building effective defenses against such risks. **Zero Day Vulnerability** - Refers to a previously unknown flaw or weakness in software, hardware, or firmware. Since the vulnerability is unknown to the developers or security community, no patch, fix, or mitigation has been created to address it. **Zero Day Exploit** - A zero day exploit is a specific piece of code, methodology, or technique created by attackers to leverage a zero day vulnerability. Essentially, it's the weapon crafted to take advantage of the vulnerability, allowing threat actors to bypass security measures, steal data, install malware, or gain unauthorized access **Zero Day Attack** - A zero day attack is the actual execution of a cyberattack using a zero day exploit against a target system. This is the active stage where the attacker weaponizes a vulnerability and attempts to cause harm, whether by stealing sensitive data, disrupting operations, or other malicious activities. ### Question: What is the Role of Threat Intelligence in Preventing Zero Day Attacks? ### Answer: Since zero day vulnerabilities are unknown before they are exploited, security teams must rely on proactive intelligence gathering to identify patterns, indicators of compromise, and potential attack vectors before they escalate into full-scale breaches. By leveraging threat intelligence, businesses can: - **Monitor emerging threats:** Security researchers and [cybersecurity](/resources/security-terms-glossary/what-is-cybersecurity) firms track malicious actors, dark web forums, and attack trends to identify potential zero day vulnerabilities before they are widely exploited. - **Enhance incident response:** When a zero day attack occurs, threat intelligence helps security teams understand the nature of the exploit and respond quickly to contain the breach. - **Strengthen** [**network security:**](/resources/security-terms-glossary/what-is-network-security) Businesses use threat intelligence to refine security policies, update intrusion detection systems, and harden defenses against evolving threats. - **Improve patch management strategies:** By identifying vulnerabilities that could be targeted, organizations can prioritize patching efforts and reduce the risk of zero day exploitation. - **Leverage machine learning for threat detection:** Advanced machine learning algorithms analyze vast amounts of security data to detect anomalies that may indicate a zero day exploit in action. ### Question: What are Some Best Practices to Protect Against Zero Day Vulnerabilities? ### Answer: Zero day attacks are challenging to defend against due to their unknown nature. However, businesses can take proactive steps to reduce their risk exposure: - **Adopt a** [**zero trust security model:**](/resources/security-terms-glossary/what-is-zero-trust-architecture) Limit access to sensitive systems and data by verifying all users and devices, regardless of location. - **Deploy** [**advanced threat protection:**](/resources/security-terms-glossary/what-is-advanced-threat-protection) Leverage solutions that use machine learning and behavioral analytics to detect unusual or malicious activity. - **Keep systems updated:** Regularly apply security patches and updates to reduce the likelihood of exploitation through known vulnerabilities. - **Implement** [**endpoint protection:**](/resources/security-terms-glossary/what-is-endpoint-security) Use robust antivirus software and endpoint detection tools to monitor devices for suspicious activity. - **Conduct regular security audits:** Assess your network security posture to identify and address potential weaknesses. - **Educate employees:** Train staff to recognize phishing attempts and other tactics commonly used to deliver zero day exploits. ### Question: Is It Possible to Completely Prevent Zero-Day Attacks? ### Answer: No, it’s not possible to completely prevent zero-day attacks because they exploit unknown vulnerabilities. However, organizations can reduce their risk by adopting a zero trust architecture and deploying proactive defenses like behavioral threat detection and real-time inspection. These strategies don’t rely on prior knowledge of threats, making them more effective against zero-day exploits than traditional signature-based tools. ### Question: How Long Does It Take for a Zero-Day Vulnerability to Be Patched? ### Answer: Patching time for a zero-day vulnerability varies widely. For critical flaws, vendors may release emergency patches within days, while less urgent updates often take weeks or months. However, attackers tend to exploit vulnerabilities quickly once discovered, so response time is vital. Organizations should deploy virtual patching or threat mitigation tools to protect vulnerable systems while waiting for official fixes. ### Question: What Types of Systems Are Most Vulnerable to Zero-Day Attacks? ### Answer: Widely used systems—like popular operating systems, web browsers, or enterprise software—are often more vulnerable to zero-day attacks because they are high-value targets for attackers. Systems with unpatched software, legacy applications, or insufficient defenses are also more at risk. Additionally, internet of things (IoT) devices and industrial control systems often lack robust security and can be easily exploited in zero-day scenarios. ### Question: Can Antivirus Tools or Firewalls Detect Zero-Day Attacks? ### Answer: Traditional antivirus tools and firewalls often struggle to detect zero-day attacks because these threats exploit unknown vulnerabilities without identifiable signatures. Advanced solutions like behavior-based monitoring, anomaly detection, and inline traffic inspection are better equipped to identify irregular activity tied to zero-day threats. ### Title: Zscaler vs. Legacy Firewalls: Securing Hybrid Infrastructure ### Description: Learn how traditional firewall appliances fail to effectively secure modern hybrid infrastructure, and why you need a cloud firewall built on zero trust. ### URL: https://www.zscaler.com/zpedia/zscaler-vs-legacy-firewalls ### Question: Zscaler vs. Legacy Firewalls ### Answer: Appliance-based firewalls struggle to secure hybrid infrastructure, leaving it vulnerable to modern threats.

Local breakouts enable organizations to offload internet-bound traffic from local branches and remote offices, and route it directly to the internet via a local internet service provider (ISP). [**Read more.**](/resources/security-terms-glossary/what-are-local-internet-breakouts) ### Question: Why Are Local Internet Breakouts Important? ### Answer: Organizations have historically deployed a hub-and-spoke architecture to route traffic, typically over multiprotocol label switching (MPLS), to a centralized data center. In this architecture, traffic runs through stacks of security appliances, such as VPNs, prior to egressing to the internet. Today, because SaaS and cloud applications, such as Microsoft 365 and Salesforce, were designed to be accessed directly via the internet, traffic patterns have shifted. Most wide area network (WAN) bandwidth is now consumed by traffic destined for the internet. Backhauling internet-bound traffic to corporate data centers no longer makes sense—it can be expensive and can increase application latency, which degrades the user experience. As organizations discover this, they are increasingly turning to local breakouts and SD-WAN to simplify the branch and more easily establish direct-to-internet connections. [**Read more.**](/resources/security-terms-glossary/what-are-local-internet-breakouts) ### Question: How Do Local Internet Breakouts Work? ### Answer: Local internet breakouts enable organizations to leverage lower-cost connections to route internet traffic to a local ISP so they can reduce the burden on the corporate network, deliver a fast user experience, and reserve MPLS for applications still residing in the corporate data center. With a software-defined wide area network (SD-WAN) as an overlay, software-defined policies are used to select the best path to route traffic connecting the branch to the internet, cloud applications, and the data center. By defining policies for all branches in the cloud through a single interface, organizations can easily deploy new applications and services as well as manage policies across many locations.

Prevention & Guidance | Zscaler ### Description: Ransomware attacks are malicious software attacks where files are encrypted or stolen, coercing victims to pay a ransom for decryption or to prevent data loss. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-are-ransomware-attacks ### Question: What Are Ransomware Attacks? TIPS & GUIDANCE ### Answer: [Ransomware](/resources/security-terms-glossary/what-is-ransomware) is a type of malware (malicious software) that “locks” a system or encrypts files, making the data inaccessible until a victim pays a specified amount of money, usually in cryptocurrency. Once the ransom payment is made, the victim is supposed to receive a decryption key to regain access to files and systems. [Read more](/resources/security-terms-glossary/what-are-ransomware-attacks). ### Question: Link Between Ransomware and Cryptocurrency ### Answer: In the beginning, ransom demands were typically a few hundred dollars because the targets were still mostly home users. Victims of ransomware would pay with standard currency, meaning the criminals responsible had a much greater chance of being identified. The rise of cryptocurrencies—digital currencies based on anonymity and encryption—has seen a reversal of fortune for these attackers. Cryptocurrencies such as bitcoin make transactions nearly impossible to trace, allowing bad actors to cover their tracks.[ Read more](/resources/security-terms-glossary/what-are-ransomware-attacks). ### Question: What is Ransomware as a Service (RaaS)? ### Answer: Ransomware as a service is a byproduct of ransomware's popularity and success. Like many legal SaaS offerings, RaaS tools are usually subscription-based. They're often inexpensive and readily available on the dark web, providing a platform for anyone—even those without programming skills—to launch an attack. If a RaaS attack is successful, the ransom money is divided between the service provider, the coder, and the subscriber.

Almost anyone can pick up and use a new cloud app, and IT can’t manually manage granular user access controls at that scale. - They can apply policy to provide shadow IT control, [cloud data loss prevention](/products-and-solutions/data-loss-prevention) ([DLP](/products-and-solutions/data-loss-prevention)), [SaaS security posture management](/products-and-solutions/data-security-posture-management-dspm) ([SSPM](/products-and-solutions/data-security-posture-management-dspm)), and [advanced threat protection](/products-and-solutions/advanced-threat-protection). [Read more](/resources/security-terms-glossary/what-is-cloud-access-security-broker). ### Question: How Do CASBs Work? ### Answer: CASB solutions can take the form of on-premises hardware or software, but they’re best delivered as a cloud service for greater scalability, lower costs, and easier management. Whatever the form factor, CASBs can be set up to use proxying ([forward proxy](/resources/security-terms-glossary/what-is-forward-proxy) or reverse proxy), APIs, or both (which is called “multimode”—more on that a bit later). ### Proxy CASBs need to operate in the data path, so the ideal CASB is founded on a cloud proxy architecture. Forward proxies are more commonly used with CASB, ensuring users’ privacy and security from the client side. Reverse proxies, on the other hand, sit with internet servers and are prone to performance degradation and request errors. A forward proxy intercepts requests for cloud services en route to their destination. Then, based on your policy, the CASB enforces functions like credential mapping and single sign-on (SSO) authentication, device posture profiling, logging, alerting, malware detection, encryption, and tokenization. ### API While an inline proxy intercepts data in motion, you need out-of-band security for data at rest in the cloud, which [CASB vendors](/partners/technology/data) provide through integrations with cloud service providers’ application programming interfaces (APIs).

[Read more](/resources/security-terms-glossary/what-is-cloud-proxy). ### Question: Benefits of a Cloud Proxy ### Answer: An effective cloud-based proxy architecture offers: 1. **Universal application awareness**, including cloud-based apps, on any port, with significantly fewer compatibility issues. 2. **Global scale** to keep up with users who are constantly in motion, often far removed from the enterprise network. 3. **Significant cost savings** compared to typical hardware proxy price points, reducing IT spend. 4. **Great user experience**, even with full TLS/SSL inspection enabled, with no detectable latency for end users. 5. **No outside visibility** into the server, with support for XFF headers for apps that require the user’s real source IP address.[Read more](/resources/security-terms-glossary/what-is-cloud-proxy). ### Question: How Does a Cloud Proxy Work? ### Answer: Here are the basic steps: Step1: Client sends a request, which the cloud proxy intercepts Step2: Cloud proxy forwards the incoming request to a firewall if applicable Step3: Firewall either blocks the request or forwards it to the server Step4: Server sends response through the firewall to the proxy Step5: Cloud proxy sends the response to the client Backed by the elasticity of the cloud, this all happens in near-real time regardless of traffic volume. ### Question: Why Do You Need a Cloud Proxy? ### Answer: A cloud proxy functions like a [reverse proxy](/resources/security-terms-glossary/what-is-reverse-proxy) in many ways—client requests flow through the cloud proxy on the way to an internet address, and replies (e.g., permission to access a webpage) return through the proxy on their way to clients—but because the cloud proxy resides in the cloud, it isn’t confined to data center hardware like a conventional appliance-based proxy. [Read more](/resources/security-terms-glossary/what-is-cloud-proxy). ### Question: Challenges with Appliance-Based Proxies ### Answer: Traditional reverse proxy servers and HTTP proxies are still commonplace in today’s network security stacks, but IT leaders increasingly cite issues with: - **Latency:** Proxies need to operate inline to intercept traffic. Routing traffic through bandwidth-limited appliances in a serial fashion can add significant latency to requests—particularly with on-site enterprise deployments—leading to a poor user experience. - **Compatibility:** Traditional proxies are prone to application compatibility issues because they weren’t built for the ways rich web-based applications perform authentication, API calls, service requests, and more, forcing additional troubleshooting. - **Cost:** Commercial proxy appliances cost too much compared to typical IT budgets—even more so if an organization wants to use them to inspect TLS/SSL traffic, for which some vendors can recommend as many as eight times more appliances. - **Caching:** Once a critical function of a proxy architecture, caching is now a feature of all modern web browsers, making network-based caching a secondary offering at best.

[Read more](/resources/security-terms-glossary/what-is-cloud-security-gateway). ### Question: How Does a Cloud Security Gateway Work? ### Answer: Cloud security gateways sit between users and their internet destinations, enforcing corporate and regulatory security policies. They differ from legacy secure web gateways (SWGs) in that they offer a complete security stack delivered as a service. All filtering, inspection, and policy enforcement happen in the cloud, so there’s no need for on-premises physical appliances. [Read more](/resources/security-terms-glossary/what-is-cloud-security-gateway). ### Question: Cloud Security Gateway Features ### Answer: Cloud security gateways are effectively an amalgam of security services designed to enforce policy in the cloud, including but not limited to: - ##### Authentication and authorization - ##### Single sign-on (SSO) - ##### Encryption - ##### API control [Read more](/resources/security-terms-glossary/what-is-cloud-security-gateway). ### Question: What Are the Benefits of a Cloud Security Gateway? ### Answer: A cloud security gateway delivers the complete security stack as a service, with in-depth protection against malware, advanced threats, phishing, browser exploits, malicious URLs, botnets, and more. A cloud native security gateway is a shift from traditional appliance models and offers a range of benefits: - ##### **Modernized Security** - ##### **Faster User Experience** - ##### **Unified Policies and Reporting** [Read more](/resources/security-terms-glossary/what-is-cloud-security-gateway). ### Title: Cloud Workload Protection Platform (CWPP) | Zscaler ### Description: A cloud workload protection platform (CWPP) is a workload-centric security solution with protections for hybrid cloud, multicloud and data center architectures. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-cloud-workload-protection-platform-cwpp ### Question: What Is a Cloud Workload Protection Platform (CWPP)? ### Answer: A cloud workload protection platform (CWPP) is a security solution built to secure workloads in modern cloud and data center environments. An effective CWPP can deliver consistent security controls and visibility for physical machines, virtual machines, containers, and serverless workloads anywhere. CWPPs scan for known vulnerabilities when workloads are deployed and secure them at runtime with identity-based microsegmentation, host-based intrusion prevention, optional anti-malware, and more. [Read more](/resources/security-terms-glossary/what-is-cloud-workload-protection-platform-cwpp). ### Question: What to Look for in a CWPP? ### Answer: As enterprises evolve, the need for a CWPP continues to grow. There are a lot of options in the market, not all of them full-featured platforms—so if you’re comparing different CWPP solutions, here are some things to keep in mind: 1. In the near future, most enterprise infrastructure will be hybrid, multicloud architecture, so an effective CWPP needs to protect physical machines, VMs, containers, and serverless workloads. 2. You should be able to manage a CWPP from one console, managed through a single set of APIs. 3. A complete CWPP offering should expose all of its functionality via APIs to facilitate automation in cloud environments. 4. CWPP vendors should be able to share a roadmap and architecture design for serverless protection.

Explore more. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-a-denial-of-service-attack ### Question: What Is a Denial-of-Service (DoS) Attack? ### Answer: A denial-of-service (DoS) attack is a cyberattack in which cybercriminals disrupt the service of an internet-connected host to its intended users. This is done by sending the targeted network or server a constant flood of traffic, such as fraudulent requests, which overwhelms the system and prevents it from processing legitimate traffic. [Read more](/resources/security-terms-glossary/what-is-a-denial-of-service-attack). ### Question: How Does a DoS Attack Work? ### Answer: In a denial-of-service attack, a hacker uses a program to flood a server with malicious traffic. The requests that make up this traffic appear to come from legitimate users, so the server validates request after request. In effect, “service” is “denied” to legitimate users due to the resulting loss of bandwidth and network resources. The attacked system or data becomes unavailable to users who need it. DoS attacks are often used for extortion because, for example, a business that can't provide its service to customers can lose revenue and suffer reputational harm. In this sense, DoS is similar to ransomware, but the hostage is the victim's service, rather than their data. [Read more](/resources/security-terms-glossary/what-is-a-denial-of-service-attack). ### Question: Some Historically Significant DoS Attacks? ### Answer: Cloud service providers often fall victim to DDoS because of their inherent vulnerability to such threats. Here are a few more recent ones that made headlines: - **Amazon:** In February 2020, Amazon suffered one of the largest DDoS attacks ever recorded. Using connectionless lightweight directory access protocol (CLDAP) reflection, attackers hit an AWS customer at a rate of 3.3 terabytes per second for three days. - **GitHub:** In February 2018, attackers blasted 1.35 terabytes per second into GitHub servers for 20 minutes. "Tens of thousands of unique endpoints” harbored “over a thousand different autonomous systems” that launched the attack. - **Google:** In October 2020, Google suffered a six-month-long UDP amplification attack that was mounted on three Chinese internet service providers (ISPs), sending more than 2.5 terabytes per second of junk data to Google servers. [Read more](/resources/security-terms-glossary/what-is-a-denial-of-service-attack) ### Question: How Can You Identify a DoS Attack? ### Answer: Infrastructure providers tend not to filter route advertisements, which tell people how to get from one place on the internet to another. More importantly, they also tend not to filter the packets to verify traffic’s source. These two conditions make it easy for bad actors to send attack traffic to a target. Attackers are generally motivated by three things: hostility toward the target, extortion, and a desire to pickpocket someone while service is being denied to them. While there is no early warning sign of a DoS attack, a savvy security professional can detect traffic a malicious actor is sending to determine whether you’re a viable target or not. The actors will send out a large number of requests, such as to different parts of a website, to see if the web servers are vulnerable to a DoS attack. These early web “tremors” are a sign that your organization may come under attack. With proper network security monitoring in place, your cybersecurity team can analyze network traffic and uncover patterns across packets that are clear-cut signs of attack. To identify whether you’re under attack in real time, you need to observe the metadata from your routers and switches—a task more easily done with a quality monitoring tool. [Read more](/resources/security-terms-glossary/what-is-a-denial-of-service-attack) ### Question: Types of DoS Attacks ### Answer: There are four main types of DoS attacks that aim your to exploit or extort systems and data: - **Browser redirection:** A user requests a page to load, but a hacker redirects the user to another, malicious page. - **Connection closure:** A bad actor closes an open port, denying a user access to a database. - **Data destruction:** A hacker deletes files, leading to a “resource not found” error when someone requests that file, or, if an application contains a vulnerability that leaves it open to injection attacks, the bad actor can deny service by dropping the database table. - **Resource exhaustion:** A bad actor will repeatedly request access to a particular resource, overloading the web application, causing it to slow down or crash by repeatedly reloading the page. [Read more](/resources/security-terms-glossary/what-is-a-denial-of-service-attack) ### Question: Types of DDoS Attacks ### Answer: Here are some specific DDoS attack examples to remember: - **SYN flood:** An attacker exploits a TCP communication (SYN-ACK) by sending a large amount of SYN packets, consuming the resources of the targeted system. - **Spoofing:** An attacker impersonates a user or device and, after gaining trust, uses spoofed packets to launch a cyberattack. - **Domain name system (DNS) flood:** Also known as a DNS amplification attack, an attacker disrupts DNS resolution of a given domain name by flooding its servers. - **Internet control message protocol (ICMP) flood:** Also known as a ping flood, an attacker forges a source IP and creates a “smurf” attack. This method can also be used to send a “ping of death,” wherein large packet causes buffer overflow. - **User datagram protocol (UDP) flood:** An attacker floods random ports on its target, which then consumes resources and responds with “destination unreachable” packets. [Read more](/resources/security-terms-glossary/what-is-a-denial-of-service-attack) ### Question: 5 ways to Prevent a DoS Attack: ### Answer: 1. **Create a DoS response plan.** Go over your system and identify any potential security flaws, vulnerabilities, or gaps in posture. Outline a plan of response in the event of an attack. 2. **Secure your infrastructure.** Effective cloud-based firewalling, traffic monitoring, and threat intelligence solutions greatly increase your chances of fending off DoS attacks. 3. **Understand warning signs.** Look for suspicious drops in network performance, website downtime, or a sudden increase in spam. All of these require immediate action. 4. **Adopt cloud-based services.** Cloud resources give you more bandwidth than on-premises ones, and because your servers aren’t all in the same locations, bad actors will have a harder time targeting you. 5. **Monitor for unusual activity.** This will allow your security team to detect and mitigate a DoS or DDoS attack in real time. [Read more](/resources/security-terms-glossary/what-is-a-denial-of-service-attack) ### Question: How Can You Reduce the Risk of a DoS Attack? ### Answer: To keep your organization secure and maximize your chances of effective DoS and DDoS mitigation, you need proper DoS and DDoS protection. Here are some ways you can lower your chances of getting “DoS’d” or “DDoS’d”: - **Get your security from the cloud.** - **Adopt extended detection and response (XDR)** - **Consider a security operations center (SOC)** - **Implement a zero trust architecture.** [Check details here.](/resources/security-terms-glossary/what-is-a-denial-of-service-attack) ### Title: What Is Forward Proxy? | Key Concepts & Definitions |Zscaler ### Description: Forward proxy stands between one or more users' devices & the internet. Requests are evaluated by forward proxy servers instead of sent directly to web servers. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-forward-proxy ### Question: What Is a Forward Proxy? ### Answer: A forward proxy is an intermediary that sits between one or more user devices and the internet. Instead of validating a client request and sending it directly to a web server, a forward proxy server evaluates the request, takes any needed actions, and routes the request to the destination on the client’s behalf. The proxy then evaluates and inspects any response, takes action as needed, and forwards it to the originating client if appropriate. [Read more](/resources/security-terms-glossary/what-is-forward-proxy). ### Question: How Does a Forward Proxy Work? ### Answer: A forward proxy is far more than a traffic controller. As an intermediary, the proxy can shield users from direct access to or from bad actors as well as prevent them from compromising data and enterprise resources—intentionally or not. It operates “inline,” sitting directly in the flow of traffic, allowing an organization to identify any challenges to security and enforce needed policies in real time. Proxies are buffers that help keep apps and data safe from harm, whether they’re the result of user errors or malicious data exfiltration and malware. [Read more](/resources/security-terms-glossary/what-is-forward-proxy). ### Question: Forward Proxy Use Cases ### Answer: As you move to the cloud, you need a security strategy built on a cloud-based proxy architecture. Here are a few major[ use cases](https://info.zscaler.com/resources-ebook-top-casb-use-cases) for organizations looking to embrace forward proxy (and CASB in particular): - ### **Shadow IT Discovery** Cloud usage is spread across SaaS applications, user groups, and locations. Unsanctioned apps (i.e.,[ shadow IT](/resources/security-terms-glossary/what-is-shadow-it)) abound, but maintaining visibility over what users access is difficult, if not impossible, without the right solutions. Forward proxy to a CASB ensures monitoring and logging of all traffic from sanctioned user devices, allowing IT to identify unsanctioned apps and govern access to them, either individually or by category. - ### **Data Protection** Because SaaS apps are built to enable fast, easy sharing, it’s common for users to upload critical business data to inappropriate locations. A cloud-based forward proxy is the best way to prevent users from[ uploading sensitive information](/products-and-solutions/data-security) to risky cloud destinations because it operates inline and has the scale to inspect all traffic—plus, it can hide IP addresses. - ### **Threat Prevention** As well as being an attractive avenue for data exfiltration, SaaS apps can be a conduit for the propagation of malware. Rapid sharing functionality can be hijacked to distribute infected files within and between organizations. A forward proxy prevents infected files from being uploaded to cloud resources by enabling technologies like[ advanced threat protection](/products-and-solutions/advanced-threat-protection) ([ATP](/products-and-solutions/advanced-threat-protection)) and[ cloud sandbox](/products-and-solutions/cloud-sandbox) to operate inline and intercept threats in transit. [Read more](/resources/security-terms-glossary/what-is-forward-proxy). ### Question: How to Choose a Forward Proxy ### Answer: The right cloud-based forward proxy enables: - Consistent data and threat protection across all your cloud data channels with one straightforward policy. - Unified security as part of a[ SASE](/resources/security-terms-glossary/what-is-sase) offering that supports use cases related to CASB,[ secure web gateway](/products-and-solutions/web-security), and[ ZTNA](/resources/security-terms-glossary/what-is-zero-trust-network-access) for securing access to cloud apps and APIs, the web, and internal resources, respectively. - IT ecosystem simplicity through a single-pass architecture that forgoes appliances and provides advanced functionality without the need for complex proxy configurations such as proxy chaining.

In a multitenant architecture, each cloud customer’s data is kept separate, and tenants are generally unaware of each other’s presence. This architecture is essential to most software-as-a-service (SaaS) offerings. [Read more](/resources/security-terms-glossary/what-is-multitenant-cloud-architecture). ### Question: How Does Multitenancy Work? ### Answer: In a multitenant environment, customers share the same application, operating environment, hardware, and storage mechanism. This is distinct from virtualization, wherein every application runs on a separate virtual machine with its own operating system. A multitenant cloud is commonly likened to an apartment building—residents have keys to their own separate apartments, but they all share the infrastructure that delivers water and power. The provider (or the landlord, in this example) sets overarching rules and performance expectations for customers (tenants), but the individual customers have private access to their data. [Read more](/resources/security-terms-glossary/what-is-multitenant-cloud-architecture). ### Question: Multitenant Cloud vs. Single-Tenant Cloud ### Answer: | **Multitenant Cloud** | **Single-Tenant Cloud** | |---|---| | Serves multiple tenants with one instance | Serves one tenant with one instance | | Makes cost-effective use of shared resources | Often costs more due to dedicated resources | | Isolates tenant data with tight access controls | Isolates tenant data with private infrastructure | | Offers efficient deployment and scalability | Meets specific data privacy requirements | | Relies on the vendor for maintenance | Relies on the operator for maintenance | [Read more](/resources/security-terms-glossary/what-is-multitenant-cloud-architecture). ### Question: Best Examples of Multitenant Cloud Architecture ### Answer: Most commercial public cloud services are based on multitenant clouds, including: - Email services like Gmail and Outlook - Streaming services like Netflix and Amazon Prime Video - CRM software like Salesforce and Oracle NetSuite [Read more](/resources/security-terms-glossary/what-is-multitenant-cloud-architecture). ### Question: Benefits of a Multitenant Cloud ### Answer: Multitenant clouds take advantage of their underlying architecture to provide: 1. **Efficiency, flexibility, and scalability:** Multitenant cloud infrastructure makes it easy to onboard groups of users because there’s essentially no difference between onboarding 10,000 users from one company or 10 users from 1,000 companies. Where other architectures can suffer outages or slowdown based on demand, multitenant clouds can easily scale and reallocate resources when and where needed. 2. **Cost savings:** Efficient usage and allocation of resources leads to lower costs. Tenants don’t pay for compute power or storage they may not use, and they need not worry about maintenance, upgrades, or updates to the infrastructure, as those responsibilities fall to the service provider. 3. **Security:** The security benefits of a multitenant cloud are often misunderstood. While it’s true that select industry and government regulations don’t permit shared infrastructure regardless of the security measures in place, a cloud provider with a [worldwide footprint](/press/zscaler-extends-edge-compute-now-operating-over-150-data-centers) can offer far superior protection with a multitenant architecture, able to implement new or updated policies on a global scale across the entire cloud. [Read more](/resources/security-terms-glossary/what-is-multitenant-cloud-architecture). ### Question: The Multitenant Advantage ### Answer: - Suboptimal user experience because of the need to backhaul traffic from the cloud to the vendor, and only then to the applications users want to access. - More complex policies that don’t translate well to SASE. - A patchwork of products or services that are connected only through an overlay user interface, not properly integrated.

[Read more](/resources/security-terms-glossary/what-is-next-generation-firewall). ### Question: Next-generation Firewall vs. Traditional Firewall ### Answer: **Traditional firewalls** only operate on Layers 3 and 4 of the Open Systems Interconnection (OSI) model to inform their actions, managing network traffic between hosts and end systems to ensure complete data transfers. They allow or block traffic based on port and protocol, leverage stateful inspection, and make decisions based on defined security policies. **NGFW**, purported at the time of its introduction as the next evolution in network security. It touted all the features one would expect from a traditional firewall, but with more granular capabilities that allow for even tighter policies for identity, user, location, and application. [Read more](/resources/security-terms-glossary/what-is-next-generation-firewall). ### Question: NGFW Features ### Answer: - **Application control:** NGFWs actively monitor which applications (and users) are bringing traffic to the network. They have an innate ability to analyze network traffic to detect application traffic, regardless of port or protocol, increasing overall visibility. - **IPS:** At its core, an IPS is designed to continuously monitor a network, look for malicious events, then take careful action to prevent them. The IPS can send an alarm to an administrator, drop the packets, block the traffic, or reset the connection altogether. - **Threat intelligence:** This can be described as the data or information collected by a variety of nodes across a network or IT ecosystem that helps teams understand the threats that are targeting—or have already targeted—an organization. This is an essential cybersecurity resource. - **Antivirus:** As the name suggests, antivirus software detects viruses, responds to them, and updates detection functionality to oppose the ever-changing threat landscape. [Read more](/resources/security-terms-glossary/what-is-next-generation-firewall). ### Question: What does an NGFW do? ### Answer: When it comes to securing corporate networks, NGFWs go beyond the call of duty compared to traditional firewalls. They dig deeper into network traffic to understand where it’s coming from. As a result, they’re able to collect a greater body of knowledge about malicious traffic and its embedded threats that are constantly trying to infiltrate the network perimeter, access corporate data, and ruin an organization’s reputation. Where a traditional firewall only operates at Layers 3 and 4, NGFWs can operate all the way up to Layer 7—the application layer. This means app-level threats, which are some of the most dangerous and penetrative, are stopped *before* they breach, saving time and cost in remediation. [Read more](/resources/security-terms-glossary/what-is-next-generation-firewall). ### Question: 4 Core Benefits of Cloud Firewalls ### Answer: - **Proxy-based architecture:** [This design](/products-and-solutions/cloud-firewall) dynamically inspects network traffic for all users, applications, devices, and locations. It natively inspects SSL/TLS traffic at scale to detect malware hidden in encrypted traffic. Plus, it enables granular network firewall policies spanning multiple layers based on network app, cloud app, fully qualified domain name (FQDN), and URL. - **Cloud IPS:** A cloud-based IPS delivers always-on threat protection and coverage, regardless of connection type or location. It inspects all user traffic on and off network, even hard-to-inspect SSL traffic, to restore full visibility into user, app, and internet connections. - **DNS security and control:** As the first line of defense, a cloud firewall protects users from reaching malicious domains. It optimizes DNS resolution to provide a better user experience and cloud application performance, which is especially critical for CDN-based apps. It also provides granular controls to detect and prevent DNS tunneling. - **Visibility and simplified management:** A cloud-based firewall delivers real-time visibility, control, and immediate security policy enforcement across the platform. It logs every session in detail, and uses advanced analytics to correlate events as well as provide insight into threats and vulnerabilities for all users, applications, APIs, and locations from a single console. [Read more](/resources/security-terms-glossary/what-is-next-generation-firewall). ### Question: Why Do I Need a Next-Generation Firewall (NGFW)? ### Answer: NGFWs provide more advanced defense against sophisticated threats than traditional firewalls, including deep packet inspection, intrusion prevention, TLS/SSL inspection, and more robust logging and reporting. NGFWs can understand the destination of application traffic, enabling them to detect and mitigate malware, zero-day attacks, and more. With so much more context, NGFWs can enforce granular policy controls over network traffic, user activity, and application usage, instead of only ports, protocols, and IP addresses. ### Question: What Is the Difference Between a Firewall and a NGFW? ### Answer: The key difference between a traditional “stateful inspection” firewall and a next-generation firewall is the way they process network traffic. Stateful inspection firewalls rely mainly on static allow/deny rules based on connection ports, protocols, and IP addresses. NGFWs, on the other hand, can understand specific applications and their traffic, inspect the content of network packets and encrypted traffic, apply identity-based policies, and more, enabling the enforcement of more granular context-based traffic controls. ### Question: What Layer Is NGFW? ### Answer: Next-generation firewalls (NGFWs) operate mainly at Layer 7 (the Application Layer) of the OSI model. Using deep packet inspection and advanced application awareness, an NGFW can identify specific applications and services, inspect their content, and assess context to inform policy enforcement. By going beyond the basic port-and-protocol inspection of traditional stateful inspection firewalls, NGFWs can more effectively defend against sophisticated threats hiding in legitimate traffic. ### Question: Where Is a NGFW Used? ### Answer: Next-generation firewalls (NGFWs) typically sit at the network perimeter, between the internal network and external environments such as the internet. They may also be deployed between internal network segments to enforce security policies and segment sensitive resources. They continue to play a role in securing [remote access through VPNs](/resources/security-terms-glossary/what-is-remote-access-vpn), protecting traditional data center perimeters, and remain in the hardware stacks of many organizations’ remote and branch locations, although the efficacy of this approach is faltering as more and more resources and data move to the cloud, blurring the definition of the “secure perimeter.” ### Question: What Are the Main Features of a Distributed Firewall? ### Answer: A distributed firewall provides centralized policy management and enforces segmentation at the level of individual workloads, such as hosts, VMs, containers, and endpoints. Features include stateful L3–L7 controls, application awareness, IPS/IDS, and URL filtering. These firewalls enable consistent policies across hybrid and multicloud environments, offer visibility into traffic, and automate changes to adapt to shifting assets. ### Question: How Do Distributed Firewalls Enhance Network Security? ### Answer: Distributed firewalls inspect east-west traffic and use identity-based, least-privilege rules to enforce segmentation and help block lateral movement. They manage rules centrally, apply consistent policies across diverse environments, and monitor traffic for context. This approach can identify and contain threats more quickly while avoiding the performance issues that stem from redirecting traffic through a centralized location for enforcement. ### Title: What Is a Remote Access VPN? | Zscaler ### Description: A remote access VPN provides users access to applications & data residing in the corporate data center or cloud, often securing user traffic through encryption. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-remote-access-vpn ### Question: What Is a Remote Access VPN? ### Answer: A remote access virtual private network (VPN) is a network security technology that allows for remote worker authentication and access to applications and data residing in the corporate data center and cloud locations through an IPsec encrypted tunnel. When apps and data were primarily in the data center, VPN connections served as a means of offering secure remote access—even for those using public Wi-Fi. [Read more.](/resources/security-terms-glossary/what-is-remote-access-vpn) ### Question: Is VPN the Same as Remote Access? ### Answer: The short answer to this question is no. A remote access VPN works by creating virtual tunnels between an organization's network and a remote user, regardless of the user's location. This allows a user to access resources on the company’s network from any IP address, and it’s one of the most commonly used means of access control when it comes to users working from remote locations. Remote access refers to an employee accessing resources offsite by any means, not just through a VPN client. Such access can be secured with remote access VPN solutions, but this can also be done with two-factor or multifactor authentication (2FA or MFA), zero trust security, and more—anything that will create secure connections for remote employees and keep hackers out. [Read more](/resources/security-terms-glossary/what-is-remote-access-vpn). ### Question: Remote Access VPN Benefits ### Answer: 1. **Keep hackers out.** VPN tunnels are encrypted, meaning that it’s twice as difficult for bad actors to breach the private network and gain access to corporate resources. 2. **Limit permissions.** Imagine a world where anyone can gain access to a company’s network. VPNs nip this problem in the bud by requiring users to authenticate their way into the network. 3. **Prevent throttling.** Because visibility from the outside is prevented by a VPN’s encrypted tunnel, bandwidth remains wider and speeds stay fast. 4. **Secure devices.** Remote desktops as well as Android and iOS devices can be protected with the help of a VPN. [Read more](/resources/security-terms-glossary/what-is-remote-access-vpn). ### Question: VPN for Remote Access Modern Pitfalls ### Answer: - Placing users on-network, which increases risk - Providing a poor end user experience - Requiring heavy configuration as well as appliances, ACLs, and firewall policies - Lacking the ability to provide application segmentation - Missing crucial visibility into app-related activity [Read more.](/resources/security-terms-glossary/what-is-remote-access-vpn) ### Question: Why Is a SASE Approach Better Than a Remote Access VPN? ### Answer: [SASE is a framework identified by Gartner](/resources/security-terms-glossary/what-is-sase) as the way to securely connect entities such as users and devices to applications and services when their locations may be anywhere. In its 2019 report, ‘The Future of Network Security is in the Cloud’, Gartner defined the SASE framework as a cloud-based security solution that offers "comprehensive WAN capabilities with comprehensive network security functions (such as SWG, CASB, FWaaS, and ZTNA) to support the dynamic, secure access needs of digital enterprises." The top **three benefits** of adopting a SASE architecture in lieu of a remote access VPN include: 1. Reduced risk 2. Improved user experiences 3.

That means no more network access and no more lateral movement. Rather than relying on physical or virtual appliances, ZTNA solutions use software to connect apps and users to the cloud, where brokered microtunnels are stitched together in the location closest to the user.

This supports security, scalability, and performance for websites, cloud services, and content delivery networks (CDNs). Reverse proxy as a cloud service is one of the deployment modes of a [cloud access security broker (CASB)](/products-and-solutions/cloud-access-security-broker-casb), designed to provide inline, real-time security for cloud-based apps, infrastructure, and other resources. [Read more](/resources/security-terms-glossary/what-is-reverse-proxy). ### Question: Difference Between a Reverse Proxy and a Forward Proxy? ### Answer: By sitting in front of a web server, a reverse proxy ensures no clients communicate directly with the server. A [forward proxy](/resources/security-terms-glossary/what-is-forward-proxy) (another CASB mode) sits in front of client endpoints to intercept incoming requests and ensure no servers communicate directly with a client. These may sound functionally similar, but forward proxies usually depend on a software agent installed on endpoints to forward traffic, while reverse proxies do not. [Read more](/resources/security-terms-glossary/what-is-reverse-proxy). ### Question: How Does a Reverse Proxy Work? ### Answer: A reverse proxy can protect sensitive data (e.g., PCI data, PII) by acting as a middleman or stand-in for the server on which that data resides. Client requests are routed first to the reverse proxy, then through a specified port in any applicable firewall, and then to the content server—and finally, back again. The client and the server never communicate directly, but the client interprets responses as if they had. Here are the basic steps: 1. Client sends a request, which the reverse proxy intercepts 2. Reverse proxy forwards the incoming request to the firewall a. The reverse proxy can be configured to respond directly to requests for files in its cache without communicating with the server—see more detail on this in the use cases 3. Firewall either blocks the request or forwards it to the server 4. Server sends response through the firewall to the proxy 5. Reverse proxy sends the response to the client [Read more](/resources/security-terms-glossary/what-is-reverse-proxy). ### Question: What Is a Reverse Proxy Server? ### Answer: “Reverse proxy server” is essentially a more formal term for a reverse proxy. (The same is true of “forward proxy server” for a forward proxy.) Today, we tend to drop “server” because it calls to mind hardware—like a physical box—whereas the technology often takes the form of an application or cloud service. [Read more](/resources/security-terms-glossary/what-is-reverse-proxy). ### Question: Reverse Proxy 4 Use Cases ### Answer: Common specific use cases for reverse proxies include: 1. ### **Securing Unmanaged Devices** 2. ### **Data Protection** 3. ### **Threat Prevention** 4. ### **Load Balancing** [Read more](/resources/security-terms-glossary/what-is-reverse-proxy). ### Question: Benefits of Using a Reverse Proxy ### Answer: With those use cases in mind, the advantages of using a reverse proxy fall into three main areas: 1. **Data security and threat prevention:** Reverse proxies provide web application firewall (WAF) functionality by monitoring and filtering traffic (including encrypted traffic) between managed and unmanaged endpoints and the web server, protecting it from SQL injection, cross-site scripting, and more. 2. **Scalability and resource management:** This is a two-part benefit. Reverse proxies support operational scale by eliminating the need to install agents on every user endpoint before you can offer secure access to managed resources. They also support infrastructure scale through load balancing capabilities for resources in high demand. 3. **Performance and productivity:** Cloud-based reverse proxies can analyze and apply security policies to traffic, including remote user traffic, without backhauling it through your data center. They also have effectively unlimited scale for inspecting TLS/SSL traffic (the majority of today’s traffic), whereas appliance-based firewalls and proxies can rarely inspect TLS/SSL encryption without major performance drops. [Read more](/resources/security-terms-glossary/what-is-reverse-proxy). ### Question: Challenges with Reverse Proxies ### Answer: Reverse proxies offer notable security benefits when it comes to securing unmanaged devices and enterprise applications, but they bring notable shortcomings, too, such as: - **No security for unmanaged resources:** If a user needs secure access to an app or resource that’s not integrated with your SSO, it’s outside a reverse proxy’s purview. Reverse proxies only monitor traffic destined for sanctioned resources, not all traffic—to secure unsanctioned resources in the same way, you’ll need a forward proxy. - **Risk of frequent breakage:** Reverse proxies are typically hardcoded to work with specific versions of applications, so when an application is updated and new code is sent to the proxy, it can break. This can make the updated application unavailable until the proxy can be recoded, which leads to frustrated users and lost productivity.

Learn about essential features, use cases, and trends. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-secure-web-gateway ### Question: What is a Secure Web Gateway (SWG)? ### Answer: A secure web gateway (SWG) is a security solution that actively monitors, filters, and enforces policies to prevent unsafe internet traffic from reaching an organization's network. Organizations use SWGs to protect users and apps from malicious websites and malware, as well as to support regulatory compliance. [Read more](/resources/security-terms-glossary/what-is-secure-web-gateway) ### Question: Why Are SWGs Important? ### Answer: The traditional office model, with local users accessing local applications, is no longer a given. Today, users and their devices can be almost anywhere. The applications they need to access, meanwhile, are increasingly in the cloud, out of reach of traditional network security. This is where SWGs provide some important benefits. [Read more](/resources/security-terms-glossary/what-is-secure-web-gateway) ### Question: What Does a SWG Do? ### Answer: A SWG (often pronounced “swig”) blocks malicious websites and links, filters web traffic, enforces usage policies, and protects users and web applications from threats. [According to Gartner](https://www.gartner.com/en/information-technology/glossary/secure-web-gateway), a SWG must include URL filtering, malicious code detection and filtering, and application controls for popular web-based apps. More recently, Gartner identified SWG as a key part of a [secure access service edge (SASE)](/resources/security-terms-glossary/what-is-sase) framework. We’ll examine that in greater detail later in this article. [Read more](/resources/security-terms-glossary/what-is-secure-web-gateway) ### Question: Is Secure Web Gateway a Firewall? ### Answer: Firewalls and SWGs perform similar tasks, but they’re not one and the same. Firewalls review the contents of incoming packets and compare their findings against a signature of known threats at the network level only. SWGs operate at the application level, and they can block or allow connections or keywords according to an organization’s web use policy. [Read more](/resources/security-terms-glossary/what-is-secure-web-gateway) ### Question: Is a Web Gateway a Proxy? ### Answer: Web gateways and proxies have key differences. A proxy server and a gateway both route traffic from a network to the internet, but a proxy server filters which connections are allowed, while a gateway doesn't do any filtering. In this sense, a gateway more closely resembles a door to get to the internet, and a proxy server a wall that bars the inside of the network from being exposed to the internet. [Read more](/resources/security-terms-glossary/what-is-secure-web-gateway) ### Question: Why Companies Need a SWG? ### Answer: Work-from-anywhere models and rapid SaaS adoption highlight the critical need for [cloud native security solutions](/products-and-solutions/web-security). The reason for this is simple: in today’s dynamic cloud environments, hardware-based approaches can't scale. Moving on-premises functions like legacy VPNs and firewalls to the cloud would be akin to networking thousands of DVD players and calling it “Netflix.” A cloud-based secure web gateway (SWG) provides consistent protection regardless of where users connect. Sitting inline between users, the web, and SaaS, it terminates and inspects every connection, applying user-centric security and access policies. This approach eliminates your attack surface, prevents compromise, stops lateral movement, and halts sensitive data loss. ### Question: How Does a Secure Web Gateway Work? ### Answer: A SWG acts as a barrier between an organization's network and the open internet, protecting it from web-based threats and ensuring users comply with web policies. When a user attempts to access a website or web content, a SWG will typically: 1. Check the URL against a database to allow or block access based on safety and policy. 2. Enforce app controls, restricting certain actions (e.g., uploads or sharing) per policy. 3. Scan downloads for malware, blocking files if the SWG detects any threats. 4. Inspect encrypted (TLS/SSL) traffic for hidden threats, re-encrypting safe data. 5. Identify sensitive data (e.g., payment info) and acts based on company policies. 6. Log user activity, threats, and violations for analysis and reporting. ### Question: SWG Features ### Answer: To support the key functions laid out above, an effective SWG includes capabilities like: - **URL filtering** to block or allow user access to websites according to policy - **Application control** to enforce policy on the usage of web-based apps and cloud services - **TLS/SSL inspection** capabilities to discover threats hiding in encrypted traffic - **Advanced threat protection**, including anti-malware, antivirus, and anti-phishing measures - **Data loss prevention (DLP)** to prevent loss or leakage of sensitive data - **Bandwidth controls** to prevent certain sites or apps from consuming excess bandwidth - **Remote user protection** to secure users operating outside the network perimeter - **Policy management** tools to help administrators set and enforce security policies ### Question: What Are the Benefits of a SWG? ### Answer: An effective SWG enables you to: - Restrict or block access to risky or malicious websites and web-based apps - Protect against phishing, ransomware, and other malware in real time - Enforce compliance with company, industry, or government regulations - Support hybrid work models with fast, seamless, and secure connections to web-based resources ### Title: What Is a Shared Responsibility Model? | Zscaler ### Description: A shared responsibility model identifies which cybersecurity processes and responsibilities belong to customers and to cloud service providers. Explore more. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-shared-responsibility-model ### Question: What is Shared Responsibility Model? ### Answer: A shared responsibility model is a cloud security and risk framework that delineates which cybersecurity processes and responsibilities lie with a cloud service provider (CSP) and which lie with the customer. With more IT architectures moving to the cloud, a shared responsibility model promotes tighter security and establishes accountability as it relates to the security of the cloud. [Read more](/resources/security-terms-glossary/what-is-shared-responsibility-model)! ### Question: Advantages of a Shared Responsibility Model ### Answer: Sharing cloud security responsibility with a service provider also lets you take advantage of: - **Lower costs:** Simply put, leveraging a provider’s security and infrastructure means less management on your end, which saves you the price of additional resources that could stretch your budget. - **Improved cybersecurity:** Clearly delineating security responsibilities in cloud infrastructure reduces the risk of mistakes that lead to vulnerabilities and data breaches. - **Reduced operational burden:** The more security responsibility your CSP takes on, the more time your team will have to focus on other priorities. [Read more](/resources/security-terms-glossary/what-is-shared-responsibility-model) ### Question: How Shared Responsibility Models Work ### Answer: Most shared responsibility models hold you, the customer, responsible for anything under your direct control: data, credentials, and configurations, as well as any functionality that sits outside the CSP’s cloud resources, such as your organization’s firewalls and other internal network security. A lack of clarity around responsibilities can contribute to misconfigurations that weaken your security posture and ultimately cause cloud security failures, so it’s critical that you understand where your organization’s security duties lie in relation to your providers’. [Read more](/resources/security-terms-glossary/what-is-shared-responsibility-model)! ### Question: Why Are Shared Responsibility Models Important? ### Answer: In an on-premises data center environment, security responsibility rests solely with the owner. Accountability for maintaining security controls, patching, and physical infrastructure falls to the organization’s security team (or other responsible party, such as IT), never the hardware vendor(s). However, when portions of a network use or are composed of private or public cloud services, some security responsibilities fall to the CSP. This is where a shared responsibility model comes in, outlining precisely which security duties, data states, locations, and so on are in the CSP’s domain and which are in the customer’s. Microsoft Azure, Google Cloud, Amazon Web Services (AWS), and other CSPs each have their own model, tailored to their specific offerings. [Read more](/resources/security-terms-glossary/what-is-shared-responsibility-model)! ### Question: Different Types of Shared Responsibility Models ### Answer: - **Software as a service (SaaS):** The CSP assumes security responsibility for the operating systems, network controls, and applications that make up the service, as well as data generated in the service. Responsibility varies for identity and directory infrastructure. - **Platform as a service (PaaS):** Here, the onus is generally less on the cloud vendor, with the security responsibility for network controls, apps, and ID/directory infrastructure varying from one service to the next. However, they’re still responsible for the operating system. - **Infrastructure as a service (IaaS):** CSPs assume the least responsibility here, with the burden solely on the customer to secure everything except for the CSP’s physical infrastructure. The customer handles all OS and application patching as well as network controls. [Read more](/resources/security-terms-glossary/what-is-shared-responsibility-model) ### Question: Shared Responsibility Best Practices ### Answer: The best practices specific to a given responsibility model come down to your unique needs and the provider’s offering, but there are some general practices to keep in mind in any shared security responsibility situation: 1. **Prioritize data security and your other responsibilities.** 2. **Know what you’ve agreed to and be ready to respond to changes.** 3. **Use modern security and visibility tools.** [Read more](/resources/security-terms-glossary/what-is-shared-responsibility-model) ### Title: What is a Software Defined Perimeter (SDP)? | Zscaler ### Description: Software-defined perimeter (SDP) is delivered by the cloud and uses business policy to determine who gets access to what resources. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-software-defined-perimeter ### Question: What Is a Software-Defined Perimeter (SDP)? ### Answer: Software-defined perimeter (SDP) is a security methodology that distributes access to internal applications based on a user’s identity, with trust that adapts based on context. Where traditional security is centralized in the data center, SDP is everywhere, delivered by the cloud. It uses business policy to determine user authentication to resources, making it an important part of securing cloud- and mobile-first organizations. [Read more](/resources/security-terms-glossary/what-is-software-defined-perimeter). ### Question: What is the purpose of SDP? ### Answer: In today’s hybrid world, a traditional hardware-defined network perimeter designed for a corporate office is no longer viable. An SDP not only reduces the risk to endpoints that connect from anywhere, but also—with the help of an SDP controller—distributes network resources more evenly. [Find out more](/resources/security-terms-glossary/what-is-software-defined-perimeter). ### Question: How Does SDP Work? ### Answer: The 4 key principles of SDP work. 1. **Trust is never implicit** 2. **No inbound connections** 3. **Application segmentation, not network segmentation** 4. **Secure internet leverage** Let's [explore](/resources/security-terms-glossary/what-is-software-defined-perimeter) above points in more detail. ### Question: SDP Use Cases ### Answer: ### While SDP has many use cases, many organizations choose to start in one of the following four areas: 1. ### **Finding a VPN Alternative** 2. ### **Securing Multicloud Access** 3. ### **Reducing Third-Party Risk** 4. ### **Accelerating M&A Integration** ### Question: SDP and Zero Trust Network Access (ZTNA) ### Answer: The[ ZTNA](/resources/security-terms-glossary/what-is-zero-trust-network-access) model has become a well-known security framework, but many people don’t realize that it was based on the same principles as SDP. In fact, ZTNA uses SDP principles and functionality. With both methods, there’s no internal network, and users are only allowed to access resources if the context behind the request (user, device, identity, etc.) is correct. Only one vendor can offer a capable ZTNA platform, and that vendor is [Zscaler](/products-and-solutions/zero-trust-exchange-zte). ### Title: What Is a Supply Chain Attack? | Zscaler ### Description: A supply chain attack is an attack against an organization’s third-party suppliers or vendors, generally carried out to gain access to a downstream target. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-a-supply-chain-attack ### Question: What Is a Supply Chain Attack? ### Answer: A supply chain attack is a type of cyberattack carried out against organizational suppliers as a means for gaining access to that organization, which tends to be a high-value target. They’re also referred to as value chain or third-party software attacks. These attacks involve a high degree of planning by threat actors, use malicious code to infiltrate an organization’s systems, and can have a devastating impact in the blast radius of the original compromise, as in the case of the 2020[ SolarWinds attacks](/resources/security-terms-glossary/what-is-the-solarwinds-cyberattack). [Read more](/resources/security-terms-glossary/what-is-a-supply-chain-attack). ### Question: How a Supply Chain Attack Works ### Answer: Supply chain attacks seek to gain access by implanting a backdoor into products, typically software, used by the target organizations. This allows the attackers to deliver automated patches or “trojanized” software updates that open the door for malware and other attacks. Once these patches are in the supply chain, the attackers have full access to the chain's resources and data. As a result, the organization the chain belongs to is left vulnerable to further compromise and data theft. [Read more](/resources/security-terms-glossary/what-is-a-supply-chain-attack). ### Question: The Impact of Supply Chain Attacks ### Answer: In the SolarWinds Orion attack in 2020, an adversary was able to gain access to SolarWinds systems through a backdoor and create trojanized updates to the SolarWinds Orion platform. The trojanized Orion update allowed attackers to deploy stealthy malware on the networks of 18,000 SolarWinds customers, which included many US government agencies and organizations, including the Pentagon, the Department of Homeland Security, the FBI, the Army, the Navy, and many more. The backdoor was delivered through a legitimate software update to a known (trusted) monitoring and management tool. After the installation of the backdoor, the adversary took steps to avert sandbox detection, including waiting days before for any callback to its command-and-control (C2) system. [Read more](/resources/security-terms-glossary/what-is-a-supply-chain-attack). ### Question: Why Supply Chain Attacks are So Dangerous? ### Answer: Security researchers state that supply chain attacks are some of the most difficult threats to prevent because they take advantage of inherent trust. Beyond that, they're difficult to detect, and they can have longer lasting residual effects. [Read more](/resources/security-terms-glossary/what-is-a-supply-chain-attack). ### Question: Does the SolarWinds Attack Highlight Supply Chain Risk? ### Answer: The SolarWinds attack demonstrates to organizations that they must have their guard up at all times when it comes to their supply chains. It displays the particular vulnerabilities of manufacturing a software supply chain, and it shows IT security leaders that once a bad actor has infiltrated one part of the chain, they’ve infiltrated the whole thing. To help you keep your organization protected from these dangerous threats, we’ve put together, in the next section, a list of best practices that, when put to good use, will keep your business protected from these groups and threats alike. [Read more](/resources/security-terms-glossary/what-is-a-supply-chain-attack). ### Question: Examples of Supply Chain Attacks ### Answer: There are two major types of supply chain attacks that focus on an organization’s supply or value lifecycle. ### **Island hopping attacks** “Island hopping” attacks occur when cybercriminals infiltrate large companies by targeting smaller organizations, or those likely to have less sophisticated security controls, that are part of the larger company’s value chain. As the name implies, the attackers “hop” from organization to organization to close in on their main target. Island hopping attacks typically target prominent organizations, which tend to rely on a broad digital ecosystem of suppliers. These may include managed services providers, hardware and software vendors, and technology and business partners, many of which are connected into various applications and databases through a plethora of vulnerable endpoints. ### **Supply chain attacks** “Supply chain” attacks, such as the[ SolarWinds cyberattack](/products-and-solutions/cyberthreat-protection), are slightly different. Instead of seeking out a partner’s vulnerabilities as a way into another company’s network, they explicitly aim to exploit the trust between legitimate organizations used in normal business operations. Island hopping and supply chain attacks have been the source of high-profile, costly breaches, but the “island” organizations can also incur severe reputational and business damages, even though they’re not the actual targets of such a campaign ### Title: What is Advanced Threat Protection?

[Read more](/resources/security-terms-glossary/what-is-advanced-threat-protection). ### Question: What are the most common Advanced Attack Methods? ### Answer: - **Phishing** lures a user into following a link from a seemingly trusted source to gain access to company credentials or information. This is the [most common method](https://www.ptsecurity.com/ww-en/analytics/advanced-persistent-threat-apt-attack-cost-report/) for APT attackers to gain access to an internal network. - **Installing malware** helps cyberattackers burrow deeper into a network once they’ve gained access, enabling them to monitor activity and collect company data. This is most often done through phishing. - **Password cracking** allows attackers to gain administrative access and have free rein within a network. - **Creating a backdoor** ensures a way back into the network if an attacker needs to leave [Read more](/resources/security-terms-glossary/what-is-advanced-threat-protection). ### Question: How does Advanced Threat Protection Work? ### Answer: ATP solutions often include: - **Network traffic** **analysis** to monitor your network for security and operational anomalies - **Threat intelligence** **sharing** to offer all of a given provider’s customers the same protection - **Sandboxing** to detect and isolate suspicious files for analysis and response [Read more](/resources/security-terms-glossary/what-is-advanced-threat-protection). ### Question: 3 key Shortcomings of Legacy Sandboxing Solutions ### Answer: However, legacy approaches to sandboxing have three key shortcomings in today’s environments: 1. **Legacy sandboxes rely on backhauling**—that is, forcing data through a central network—because they’re tied to hardware in a data center, making them too slow to effectively protect a growing remote workforce. 2. **Legacy sandboxes use Terminal Access Point (TAP) mode** to inspect suspicious files, performing analysis as the files travel to a destination. The sandbox sends an alert if it detects a threat, but because TAP inspection doesn’t actually block files, it’s often too late. 3. **Legacy sandboxes can’t effectively inspect encrypted traffic** without slowing it to a crawl. Most malware is delivered over encrypted channels today, and some organizations would need [eight times as many sandbox appliances](/resources/solution-briefs/add-advanced-threat-protection-to-close-your-security-gaps.pdf) to get enough processing power.

Deployed from the cloud, cloud DLP can protect sensitive data such as personally identifiable information (PII), credit card numbers, intellectual property, and more, wherever it lives or flows. [Read more](/resources/security-terms-glossary/what-is-cloud-dlp-data-loss-prevention). ### Question: Why Cloud DLP Is Essential for Modern Businesses? ### Answer: In the era when sensitive information was printed on paper, loss prevention could be as simple as a locked file cabinet. Now, data races between [data centers](/zpedia/what-is-data-center), cloud providers, and endpoint devices, potentially subject to myriad vulnerabilities along the way. To protect it against unauthorized access, you need to implement a comprehensive data loss prevention (DLP) strategy. Your DLP strategy should bring your business and IT leaders together to identify what constitutes “sensitive data” for your organization, agree on how this data should be used, and delineate what a violation looks like. These information security guidelines, including data classification, data privacy and compliance information, and remediation procedures, can then be translated into DLP policy. Various compliance standards (e.g., GDPR, HIPAA, PCI DSS) might require your organization to deploy DLP to avoid fines or restrictions to your operations, but [data breaches](/zpedia/what-data-breach) can also expose end users' personal data, putting your organization at risk of losing customers, incurring brand damage, or facing legal consequences. With a well-defined DLP policy bolstered by well-managed supporting technology, you can significantly reduce these risks. [**Learn more**](/resources/security-terms-glossary/what-is-cloud-dlp-data-loss-prevention)**.** ### Question: Understanding the Risks of Data Loss in the Cloud Era ### Answer: As organizations accelerate their cloud adoption and fine-tune their hybrid work models, the attack surface has expanded dramatically. Today's threat landscape presents unique challenges that traditional security approaches struggle to address, requiring organizations to understand and mitigate the following critical risks: - [**Shadow IT**](/resources/security-terms-glossary/what-is-shadow-it) **and unsanctioned cloud applications:** Employees increasingly use unauthorized cloud services to share and store sensitive data, creating visibility gaps where IT teams cannot monitor or protect critical information flowing outside approved channels. - **Sophisticated** [**ransomware**](/resources/security-terms-glossary/what-is-ransomware) **and** [**supply chain attacks**](/resources/security-terms-glossary/what-is-a-supply-chain-attack)**:** Modern [threat actors](/zpedia/what-is-a-threat-actor) target cloud infrastructure and third-party integrations to encrypt or exfiltrate data at scale, exploiting trust relationships and API connections to maximize damage across interconnected systems. - **Remote workforce vulnerabilities:** With distributed teams accessing corporate data from personal devices and unsecured networks, organizations face increased exposure to data leakage through unmanaged endpoints, public Wi-Fi, and compromised home networks. - **Cloud misconfigurations and API exposures:** Complex cloud environments often suffer from misconfigured storage buckets, excessive permissions, and exposed APIs that inadvertently make sensitive data accessible to unauthorized parties or the public internet. [Read more](/resources/security-terms-glossary/what-is-exact-data-match). ### Question: Top Benefits of Using Cloud-Based Data Loss Prevention (DLP) ### Answer: Cloud-based DLP offers several advantages to any organization, providing: - **Easy scalability** to meet the needs of growing data volumes and changing information ecosystems - **Lower infrastructure** costs due to eliminating on-premises hardware and related refresh/maintenance expense - **Protection for users and branches** anywhere without the need to backhaul to your data center - **Faster deployment and configuration** than on-premises DLP, with no boxes to manage - **Automatic updates** from the cloud, providing the latest intel and new features without downtime [Learn more](/resources/security-terms-glossary/what-is-cloud-dlp-data-loss-prevention). ### Question: How Cloud DLP Works: Key Techniques and Strategies ### Answer: In the simplest terms, DLP technology, including cloud-based DLP, works by identifying sensitive data in need of protection, and then protecting it. A DLP solution may be designed to identify data in use, data in motion, or data at rest (or any combination) and determine whether it is sensitive. To do this, DLP agents may use many different techniques, such as: - **Rule-based matching or "regular expressions":** This technique identifies sensitive data based on prewritten rules (e.g., 16-digit numbers are often credit card numbers). Because of a high false positive rate, rule-based matching is often only a first pass before deeper inspection. - [**Exact data matching**](/resources/security-terms-glossary/what-is-exact-data-match) **(database fingerprinting):** This technique identifies data that exactly matches other sensitive data already fingerprinted, usually from a provided database. - **Exact file matching:** This technique works essentially like exact data matching, except it identifies matching file hashes without analyzing the file's contents. - **Partial document matching:** This technique pinpoints sensitive data by matching it to established patterns or templates (e.g., the format of a standard patient form in an urgent care facility). - **Machine learning, statistical analysis, etc.:** This family of techniques relies on feeding a learning model a large volume of data in order to "train" it to recognize when a given data string is likely to be sensitive. This is particularly useful for identifying unstructured data. - **Custom rules:** Many organizations have unique types of data to identify and protect, and most modern DLP solutions allow them to build their own rules to run alongside the others. ### Question: Main Use Cases for Cloud DLP ### Answer: As we've already covered, securing sensitive data protects your organization against other forms of loss—of customers, of revenue, of reputation—and helps you comply with industry and legal regulations. Protecting this data naturally requires being able to identify what and where it is, which constitutes another key use case: data visibility. So, in short, the main use cases for a DLP solution are: - [**Protecting sensitive data**](/resources/security-terms-glossary/what-is-data-protection) **in motion and at rest:** DLP protects data as it moves among or is stored within multiple endpoints, networks, and clouds by providing encryption, enforcing access controls, and monitoring for suspicious activities. - **Staying compliant with regulations:** DLP policies and technologies help you enforce access controls, monitor usage, and conduct audits to ensure you handle sensitive data in alignment with regulations like GDPR, HIPAA, and PCI DSS. - **Getting visibility into your data:** DLP provides data visibility—insights into where sensitive information resides and moves, who has access, and how it is used—to help you identify vulnerabilities, detect risky activity, and ultimately remediate and stop data breaches. - **Securing remote work environments and personal devices:** With the rise of remote workforces and bring your own device (BYOD) policies, DLP helps enforce security policies across a diverse range of devices and locations, reducing the risk of data leakage outside traditional network boundaries. ### Question: 5 Types of Cloud DLP Solutions ### Answer: - [**Cloud access security brokers (CASBs)**](/resources/security-terms-glossary/what-is-cloud-access-security-broker) monitor and control user activity and data transfers between endpoints and cloud apps, enforcing security policies to prevent unauthorized access, data leaks, and compliance violations. CASB offers visibility into user behavior, app usage, and data storage in cloud environments. - **DLP software** protects sensitive data against data leakage across endpoints, email, cloud services, and other channels. By monitoring data and enforcing policies in real time, DLP software identifies and prevents potential breaches. - **User and entity behavior analytics (UEBA)** monitor, analyze, and correlate user behavior, access patterns, system events, and more to detect anomalies and potential threats, such as malicious [insider threats](/zpedia/what-are-insider-threats), compromised accounts, and [lateral movement](/zpedia/what-is-lateral-movement). - [**SaaS security posture management (SSPM)**](/zpedia/what-saas-security-posture-management-sspm) helps organizations assess and manage security configurations, permissions, and vulnerabilities across different SaaS apps to address security gaps and mitigate risks associated with data exposure and unauthorized access. - [**Browser isolation**](/resources/security-terms-glossary/what-is-remote-browser-isolation) executes web content in a secure environment, preventing potentially malicious web content (e.g., drive-by downloads, [malware](/resources/security-terms-glossary/what-is-malware), [phishing](/resources/security-terms-glossary/what-is-phishing)) from directly accessing or affecting the user's endpoint, network, or sensitive data. ### Question: Why Cloud DLP Is Critical for the Modern Cloud and Mobile-First Enterprise ### Answer: To address the data protection challenges that accompany digital transformation and overcome the weaknesses of traditional enterprise DLP, you need a new mindset and new technology. Reconfiguring a traditional hardware stack for the cloud isn’t enough—it's inefficient and lacks the protection and services of a cloud-built DLP solution, including: - **Identical protection** for all users on- or off-network, ensuring comprehensive data protection for all users, wherever they are—at HQ, a branch, an airport, or a home office. - **Native inspection** of TLS/SSL-encrypted traffic, giving the organization crucial visibility into the traffic where more than 85% of today’s attacks hide. - **Elastic scalability** for inline inspection, preventing data loss by inspecting all traffic as it comes and quarantining. ### Question: Cloud DLP Best Practices ### Answer: The perfect DLP strategy depends on your organization’s data and its needs, so the best practices will vary—but that’s a subject for an entire article. Here, we’ll look at some broader DLP best practices that apply in any situation: - **Start in monitor-only mode** when you first deploy to get a sense of the data flow across your organization to inform you on the best policies. - **Keep employees in the loop** with user notifications so that policies aren't executed without their knowledge, as this can disrupt workflows and frustrate them. - **Ensure your users can submit feedback** on notifications (to justify their actions or flag broken policies), which you can use to refine your policies. - **Leverage advanced classification** measures like EDM to reduce false positives. ### Title: What Is Cloud Enclaving? | Core Concepts & Benefits |Zscaler ### Description: Cloud Enclaving prevents overprivileged access to internal resources and protects cloud infrastructure, apps, and sensitive data. See what's new. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-cloud-enclaving ### Question: What Is an Enclave? ### Answer: An enclave is a portion of a network that’s separated from the rest of the network and governed by granular security policies. The purpose of a secure enclave is to enforce [least-privileged access](/resources/security-terms-glossary/what-is-least-privilege-access) to critical resources as part of a defense-in-depth security strategy. [Read more](/resources/security-terms-glossary/what-is-cloud-enclaving). ### Question: What is Cloud Enclaving? ### Answer: Cloud enclaving is a method of segmenting workloads in a cloud environment to control access as well as secure cloud infrastructure, apps, and sensitive data against self-propagating malware, data breaches, and other attacks. Cloud enclaves use a software-defined perimeter (SDP) to create protected infrastructure in which to deploy access control, trust assessment, certificate management, and more. Cloud enclaving is also called cloud workload segmentation or cloud microsegmentation. [Read more](/resources/security-terms-glossary/what-is-cloud-enclaving). ### Question: How Does Cloud Enclaving Differ from Traditional Cybersecurity? ### Answer: Cloud enclaving is built to meet the needs of modern digital business in a way legacy security solutions aren’t. Let’s put this into historical context to understand why. Years ago, when applications and data resided in an organization’s on-premises data center—and employees largely worked from those same premises—traditional perimeter-based network security offered a reasonable level of security. Today, globalization and hybrid work have pushed cloud computing to the fore, rendering older models ineffective. In the cloud, a single organization’s different critical workloads can sit with multiple cloud service providers (e.g., Amazon Web Service \[AWS\], Microsoft Azure), and users access them over the internet. In practical terms, this means there’s no longer a “network perimeter,” which opens up many more avenues for possible attacks. Cloud enclaving counters this by making room for tailored security policies that limit traffic to and from specific workloads to only what’s explicitly permitted. [Read more](/resources/security-terms-glossary/what-is-cloud-enclaving). ### Question: What Are the Benefits of Cloud Enclaving? ### Answer: Like network segmentation, cloud enclaving exists to strengthen network and data security in the face of a growing, evolving cyberthreat landscape. Organizations are under threat across regions and industries as cybercriminals develop ever-more sophisticated techniques to evade security measures. To keep up, organizations and their security need to adapt. An effective cloud-based microsegmentation approach offers: 1. **Proactive network and IT security** 2. **Reduced vulnerability** 3. **Continuous risk assessment** 4. **Easier policy management** [Read more](/resources/security-terms-glossary/what-is-cloud-enclaving). ### Question: Best Practice for Cloud Enclaving ### Answer: Cloud enclaving addresses numerous cloud security use cases that traditional approaches simply weren’t built to support. Where network segmentation relies on coarse, management-intensive controls, microsegmentation applies controls to individual workloads, which then follow the workloads throughout your cloud environment. In our world of global hybrid workforces, distributed data, and increasingly clever attacks, cloud enclaving is an essential means of achieving: 1. **Visibility Across Your Environment** 2. **Protection Across Providers and Deployments** 3. **Reduced Capex and Opex Costs** [Read more](/resources/security-terms-glossary/what-is-cloud-enclaving). ### Title: What Is Cloud Encryption? Encrypted Cloud Storage Benefits ### Description: Learn the basics of cloud encryption and the benefits of encrypted cloud storage against cyberthreats. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-cloud-encryption ### Question: What Is Cloud Encryption? ### Answer: Cloud encryption is a data security process in which plaintext data is encoded into unreadable ciphertext to help keep it secure in or between cloud environments. It is one of the most effective ways to uphold data privacy as well as protect cloud data in transit or at rest against cyberattacks. Anywhere, anytime access to apps and data is a key advantage of the cloud, but such ubiquitous access—often to sensitive data—requires strong data protection, of which cloud encryption is a crucial part. [Read more](/resources/security-terms-glossary/what-is-cloud-encryption). ### Question: Types of Data Encryption ### Answer: Two Basic Types of Data Encryption 1. **Symmetric Encryption** 2. **Asymmetric Encryption** Compared to symmetric encryption, the biggest downside to asymmetric encryption is that, broadly speaking, it tends to be slower. [Read more](/resources/security-terms-glossary/what-is-cloud-encryption). ### Question: Benefits of Cloud Encryption ### Answer: Whatever form it takes, the core advantages of any cloud encryption center on: - **Better cybersecurity:** Protect data against compromise wherever it is, in motion or at rest, in the cloud or with an end user. - **Tighter compliance:** Meet the encryption requirements of regulatory standards such as HIPAA, PCI DSS, and FIPS. - **Lower risk:** Some data breaches may not need to be disclosed if all data involved in the breach was encrypted. - **Stronger trust and privacy:** Reinforce trust in your organization, brand, or product by emphasizing privacy in data handling, bolstered by effective encryption.

Discover more! ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-ciem ### Question: What is CIEM (Cloud Infrastructure Entitlement Management)? ### Answer: Cloud infrastructure entitlement management (CIEM) is a type of automated [cloud security](/resources/security-terms-glossary/what-is-cloud-security) solution that mitigates the risk of data breaches in public cloud environments. CIEMs prevent excessive entitlements by continuously monitoring the permissions and activity of entities to ensure they’re operating within appropriate access controls. An effective CIEM solution provides comprehensive reporting to help streamline access management, strengthen cloud security posture, and minimize DevOps disruption. [Read more](/resources/security-terms-glossary/what-is-ciem). ### Question: Components of CIEM ### Answer: - ##### **Identity governance:** Rules that determine which human and nonhuman entities are subject to which policies - ##### **Security policies:** Rules that determine the who, what, when, where, and why of cloud and workload access - ##### **Centralized management:** A dashboard that lets your team manage your entire multicloud ecosystem from one place [Read more](/resources/security-terms-glossary/what-is-ciem). ### Question: Why Are CIEM Solutions Necessary? ### Answer: Modern organizations continue to migrate more of their core operations to the cloud, extending processes and associated workloads, applications, and data across platforms from cloud service providers such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Some multicloud environments can include all of these and more. A single organization’s cloud ecosystem can have millions of individual permissions granted to people, systems, and cloud services, including non-federated accounts, default and misconfigured permissions, and even unused permissions. Left unchecked, these massively widen your attack surface, making it easier for attackers to infiltrate cloud deployments. **According to Gartner projections, by 2023, 75% of cloud security failures will result from inadequate management of identity, access, and privileges.** Widely used legacy security solutions such as privileged access management (PAM) don’t fully address modern entitlement issues—they either can’t keep up with the ephemeral, flexible nature of the cloud, or they focus on cloud configuration without offering visibility into enterprise entitlements. CIEM addresses these issues by providing deep visibility into cloud entitlements alongside automated remediation to help your organization maintain least-privileged access. [Read more](/resources/security-terms-glossary/what-is-ciem). ### Question: Role of CIEM in Modern Cloud Security ### Answer: For a typical modern organization, managing cloud access risk is more than just knowing who has access to what. In fact, in many cases, there’s no “who” to manage at all. More than half of today’s cloud entitlements are granted to applications, machines, and service accounts. [OT](/resources/security-terms-glossary/what-is-operational-technology-ot-security) (e.g., factory floor servers and robots) and IoT devices (e.g., card readers, shipping trackers, printers) connect to applications and databases that also interconnect and constantly exchange information. Entitlements need to be finely delineated to prevent inappropriate data sharing. However, with potentially thousands of users and services, tens of thousands of resources, and tens of millions of individual entitlements to manage, a human team simply can’t act quickly or accurately enough to keep up as requirements change. In today’s environments, only CIEM and the power of automation can do that. [Read more](/resources/security-terms-glossary/what-is-ciem). ### Question: Challenges of Entitlement Management ### Answer: - ###### **Overcome** **roadblocks to fast, agile DevOps** so developers can continue to deploy code quickly and securely - ###### **Manage** **complex monitoring and governance** in dynamic multicloud environments that can span the globe - ###### **Rein in excessive permissions** to prevent misuse or abuse by human and nonhuman accounts, including privileged accounts - ###### **Maintain visibility and ensure compliance** across multiple cloud infrastructures with different security frameworks, governance requirements, etc. ### Question: Benefits of CIEM ### Answer: - ### **Speed and Agility for DevOps** - ### **Visibility from a Single Dashboard** ### Title: What Is Cloud Security Posture Management (CSPM)? - Zscaler ### Description: Cloud security posture management (CSPM) scours cloud environments and alerts staff to configuration vulnerabilities. Learn more from the experts at Zscaler. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-cloud-security-posture-management-cspm ### Question: What Is CSPM? ### Answer: Cloud security posture management (CSPM) is a key component of cloud data security that scours cloud environments and alerts staff to compliance risks and configuration vulnerabilities in cloud services, most of which stem from human error. CSPM products automate security and compliance assurance and address the need for proper control over cloud infrastructure configurations. [Learn more](/resources/security-terms-glossary/what-is-cloud-security-posture-management-cspm). ### Question: ‎Why is CSPM so Important? ### Answer: The adoption of cloud services and cloud-based applications has been a boon to businesses and employees, enabling new levels of productivity and flexibility. As these tools are open to the internet and readily available to anyone, they can expose businesses to greater risk of cybersecurity threats, including data breaches. Despite training and everyone’s best efforts, vulnerabilities remain and security issues arise, putting sensitive data at risk. [Read more](/resources/security-terms-glossary/what-is-cloud-security-posture-management-cspm). ### Question: What are the key capabilities of CSPM? ### Answer: 1. Identify your cloud environment footprint and monitor for the creation of new instances or storage resources, such as S3 buckets. 2. Provide policy visibility and ensure consistent enforcement across all providers in multicloud environments. 3. Scan your compute instances for misconfigurations and improper settings that could leave them vulnerable to exploitation. 4. Scan your storage buckets for misconfigurations that could make data accessible to the public. 5. Audit for adherence to regulatory compliance mandates such as HIPAA, PCI DSS, and GDPR. 6. Perform risk assessments against frameworks and external standards such as those put forth by the International Organization for Standardization (ISO) and the National Institute of Standards and Technology (NIST). 7. Verify that operational activities (e.g., key rotations) are being performed as expected. 8. Automate remediation or remediate at the click of a button. [Read more](/resources/security-terms-glossary/what-is-cloud-security-posture-management-cspm). ### Question: How does CSPM work? ### Answer: [CSPM](/products-and-solutions) protects you in three ways: 1. #### **Provides visibility into your cloud assets and configurations.** Enterprise CSPM discovers misconfigurations, changes in policy or metadata, and more, and helps you manage all these policies through a centralized console. 2. #### **Manages and remediates misconfigurations.** By comparing your cloud configurations against industry standards and other pre-built rules, CSPM reduces human error that can increase your risk of costly breaches. 3. #### **Discovers new potential threats.** CSPM monitors your cloud environments in real time for inappropriate access and anomalies that may indicate malicious activity.

Possible poor partnership/deployment strategy 3. Unauthorized access to resources, which increases the attack surface [Read more](/resources/security-terms-glossary/what-is-cloud-security). ### Question: 5 Common Cloud Security Challenges ### Answer: 1. **Identity and Access Control**: Cloud providers continue to add more services, and the average number of distinct entitlements for these services now exceeds 5,000. This volume of entitlements can be challenging to manage using traditional identity and access management (IAM) approaches. 2. **Logging, Monitoring, and Incident Response**: Comprehensive and accurate logs are the cornerstone for a proper incident response. The case for many companies is that their install accounts are ill-equipped for this purpose and are unable to sufficiently log everything, as such. 3. **Storage and Encryption**: Queueing and notification services often hold sensitive information before it’s processed and proper security measures applied. The sensitivity of this is frequently overlooked—many services lack server-side encryption. 4. **Cloud Ransomware**: Cloud environments are not immune from malware and ransomware attacks. The most common ways attackers infiltrate businesses are by taking advantage of a 'misstep' or ‘misconfiguration’, such as an improperly configured asset, exploiting weak passwords, or exploiting insufficient policy controls. 5. **Supply Chain Attacks In the Cloud**: Cloud environments are at increased risk of a supply chain attack and can even lead to compliance risks. Security teams need to focus on minimizing the risk of third parties in a cloud environment, because it provides room for a supply chain attack. [Read more](/resources/security-terms-glossary/what-is-cloud-security). ### Question: What Is Cloud Computing? ### Answer: Cloud computing, more often just “the cloud,” is increasingly dominant worldwide as a means of accessing applications, data, systems, and more over the internet, instead of only on local hardware or networks. It allows organizations to entrust some of their data, apps, and infrastructure to third parties, which manage and secure those resources to varying degrees depending on the service. [Read more](/resources/security-terms-glossary/what-is-cloud-security). ### Question: 4 Pillars of Cloud Security ### Answer: Cloud security aims to protect more than just the perimeter, bringing security all the way down to the data. The four most common cloud security solutions include: - **Identity and access management (IAM)** to help provision access to resources in cloud environments. IAM also helps you prevent unauthorized access to data, apps, and infrastructure shared across clouds. - [**Data loss prevention (DLP)**](/resources/security-terms-glossary/what-is-cloud-dlp-data-loss-prevention) to monitor and inspect data to prevent exfiltration. DLP is an essential element of cloud computing security that a traditional security model can’t carry out effectively. - **Data encryption** to encode data so that attackers can’t interpret it without decrypting it. Encryption also helps establish trust and preserve anonymity, and is required by various privacy regulations worldwide. - **Security information and event management (SIEM)** to analyze security logs in real time, giving your security team increased visibility over your cloud ecosystem. [Read more](/resources/security-terms-glossary/what-is-cloud-security). ### Question: How Does Cloud Security Work? ### Answer: A cloud environment is only as secure as its weakest point, so effective cloud security means multiple technologies working together to protect data and applications from all angles. This often includes firewalls, identity and access management (IAM), segmentation, and encryption, though security needs can vary by the type of cloud deployment. Rather than protecting a perimeter, cloud security protects resources and data individually. This means implementing more granular and specific security measures, such as [cloud security posture management](/resources/security-terms-glossary/what-is-cloud-security-posture-management-cspm) ([CSPM](/resources/security-terms-glossary/what-is-cloud-security-posture-management-cspm)), data protection, data security, and disaster recovery as well as a bevy of tools to meet compliance requirements. [Read more](/resources/security-terms-glossary/what-is-cloud-security). ### Question: Cloud Service Types ### Answer: The four cloud deployment subtypes are: - **Private cloud:** Dedicated infrastructure used by one organization and owned by a third party or the organization itself, which is responsible for all aspects of security management - **Public cloud:** Infrastructure owned by a third party and shared among multiple organizations, which also share security responsibilities with the provider per the [shared responsibility model](/resources/security-terms-glossary/what-is-shared-responsibility-model) - **Hybrid cloud:** A combination of private and public deployment where an organization uses each for its strengths, such as scalability (public cloud) or stricter controls (private cloud) - **Multicloud:** Shared infrastructure, generally used by organizations that need access to the same applications and/or have the same segmentation and privacy requirements (e.g., PCI DSS) [Read more](/resources/security-terms-glossary/what-is-cloud-security). ### Question: Why is Cloud Security Important? ### Answer: The advent of remote work and cloud adoption has accelerated digital transformation, but as workforces, data, and apps have become more distributed, legacy networking models—built around local workers and resources—have made them slower and less secure. To make up for their losses in security, productivity, and user satisfaction, organizations need to reconsider how they protecting their environments. Ironically, many organizations cite security concerns as a primary reason not to move to the cloud. But today, in a complex economy driven by innovation—and shadowed by the growing business of cybercrime—organizations need the flexibility and scalability of cloud services, which can only be effectively secured by cloud security solutions that rise to meet the unique needs of the cloud. [Read more](/resources/security-terms-glossary/what-is-cloud-security). ### Question: Cloud Security vs. Traditional Network Security ### Answer: Network security stacks were designed to protect enterprise networks, not the cloud. They can’t provide the comprehensive cybersecurity and cloud data protection today’s cloud-based applications and mobile users need. To support business-critical SaaS apps (e.g., Microsoft 365) and handle other bandwidth-hungry services as well as more network traffic without added costs or complexity, you need a multitenant security platform that scales elastically. You’ll never get that with a traditional network security architecture. The best way to secure apps, workloads, cloud data, and users—no matter where they connect—is to move security and access controls to the cloud. Cloud-based security is always up to date, able to protect your data and users from the latest ransomware and other sophisticated threats. [Read more](/resources/security-terms-glossary/what-is-cloud-security). ### Question: Why Should You Embrace Zero Trust? ### Answer: Endpoints, resources, and data are everywhere, and the benefits of the cloud are quickly overtaking reliance on on-premises technology. Securing cloud environments means investing in[ technologies](/resources/security-terms-glossary/what-is-cloud-security) that will prevent data breaches while helping users stay satisfied and productive, and today, [zero trust](/resources/security-terms-glossary/what-is-zero-trust) is the only security paradigm today that can offer that. According to [Cybersecurity Insiders](/blogs/product-insights/2019-zero-trust-adoption-report-what-your-peers-are-doing-around-zero-trust), 72% of organizations are prioritizing zero trust adoption. They understand that archaic, siloed security tools simply don’t have the capacity or scalability to protect all your cloud resources, wherever they’re being accessed from. As you evaluate zero trust offerings, keep something in mind: any vendor can say they offer zero trust. Many vendors bolt a cloud platform onto a legacy network appliance and call it “cloud ready.” You need a partner with a zero trust solution that was built in the cloud, for the cloud.

Orchestrated response [Read more](/resources/security-terms-glossary/what-is-deception-technology). ### Question: What Types of Threats Can Deception Technology Detect? ### Answer: You can use deception technology to detect threats across the kill chain, from reconnaissance through data theft. There are three broad categories of use case: - **Perimeter deception defense:** It’s usually not feasible to monitor all incoming traffic for potential threats. Setting up deceptive public-facing assets can simplify this problem and give you actionable intel on who is targeting you. - **Network deception defense:** Planting decoys in places an attacker might peruse, but that legitimate users would never need to access, can identify an attack in progress. - **Endpoint deception defense:** Endpoint decoys look to an attacker like valuable assets ripe for exfiltration. Monitoring these assets can detect suspicious behavior as well as behavior that would be the norm on the network but has no legitimate place on a particular endpoint at a particular time. [Learn more](/resources/security-terms-glossary/what-is-deception-technology). ### Question: Challenges of Legacy Detection Technology ### Answer: - **Low-fidelity alerts** because these tools can only see their specific slice of the security infrastructure without context. - **Longer investigation time** as security analysts must pivot between multiple tools to uncover the attack sequence and scope of damage. - **High false positive rates**, causing alert fatigue. [A 2021 survey by ESG](https://assets.ctfassets.net/6pk8mg3yh2ee/2ROnWrnlNeMekgOgvb4Jm0/004ef415e2bbd4c1f5939cdd676518e7/ESG-Research-Insights-Paper-Fastly-Web-App-and-API-Protection-July-2021_English_FINAL.pdf) found that 45% of alerts from respondents' web application and API security tools were false positives.

[Deception technology](/products-and-solutions/deception-technology) will make them waste their time exploring worthless planted assets while you bait them into a trap. Once they reveal their presence, you get an early indicator of their behavior and can gain intelligence to use against them. Modern-day deception technology defenses borrow heavily from military deception principles employed by the likes of Chanakya, Sun Tzu, Napoleon, and Genghis Khan to conquer continents through deceit, camouflage, and subterfuge. In the context of cybersecurity, defenders use decoys and lures to mislead attackers into believing they have a foothold in the network and revealing themselves.

Honeypots are unprotected but monitored assets designed to attract attackers who have breached a network. Once the honeypot is accessed, security operations teams can act to gain intelligence on the attacker or shut the attack down. Older[ deception technologies](https://www.smokescreen.io/6-ways-deception-technology-levels-up-your-soc/) like honeypots, honey credentials, and such are essentially reactive, static techniques. They can fall out of date quickly and can't keep up with changing attacker tactics, making it easier for attackers to evade detection and dwell in the network. Honeypots and honeynets accessible to the internet can result in many false positives if the technology can't differentiate between broad scanning activities and targeted reconnaissance.

Learn to defend against this threat with zero trust security. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-double-extortion-ransomware ### Question: What Is Double Extortion Ransomware? ### Answer: Double extortion ransomware is a type of cyberattack in which threat actors exfiltrate a victim’s sensitive data in addition to encrypting it, giving the criminal additional leverage to collect ransom payments. A typical ransomware attack will only encrypt a victim’s data. The added threat of exfiltration makes this attack especially dangerous for organizations in all industries. [Read more](/resources/security-terms-glossary/what-is-double-extortion-ransomware). ### Question: What Happens During a Double Extortion Attack? ### Answer: In a double extortion [ransomware attack](/resources/security-terms-glossary/what-are-ransomware-attacks), a ransomware operator gains access to a victim’s network using any of a variety of established methods and threat vectors. The operator then performs network discovery to locate and secure access to high-value assets from across the network and connected endpoints, and then exfiltrate them to the operator's own storage network. After spreading laterally throughout the network, the threat actor encrypts the data and demands a ransom. If the ransom is not paid, the criminals will often sell the stolen data or publish it in public blogs and online forums. [Read more](/resources/security-terms-glossary/what-is-double-extortion-ransomware). ### Question: How Do Cyber-Attackers Gain Access? ### Answer: Attackers have long-established methods of gaining access to organizations’ private systems or endpoints, and typically, those uses for carrying out double extortion are no different: - Phishing - Malware - Vulnerability exploits - Brute-forcing an RDP server - Stolen credentials [Read more](/resources/security-terms-glossary/what-is-double-extortion-ransomware). ### Question: Attack Sequence of Double Extortion Ransomware ### Answer: The kill chain for double extortion ransomware is slightly different from that of typical ransomware. Of course, with double extortion, there are two separate methods of attack that take place within the single perpetration. Here is the kill chain: - **Initial access:** In this phase, the attacker is able to break into a user’s or organizations’ systems by using one of the methods listed above. - **Network recon and lateral movement:** The bad actor surveys the security landscape to see where they may be detected. Once they have free rein across resources, the attacker moves throughout different parts of the network. - **Data exfiltration (extortion tactic #1):** In the first step of double extortion, data is removed from the device, but not yet held for ransom. To that end, the user is also not yet notified of their data being held hostage. - **Ransomware deployment (extortion tactic #2):** This stage takes place during all ransomware attacks. The ransomware is deployed and executed, and the data is encrypted. - **DDoS attack on site or network:** At this point, the attack is in full force. The user is notified of the attack on their system, and they’re given instructions to pay a ransom in order to get their data back. [Read more](/resources/security-terms-glossary/what-is-double-extortion-ransomware). ### Question: Most Popular Double Extortion Ransomware ### Answer: Since late 2019, the following ransomware families have been the most active in executing double extortion ransomware attacks.

This is significant given that most people are connecting to apps off the corporate network, outside of firewalls and network-based mobile devices, which can make threat detection and remediation more difficult. This is especially true when you factor in that many companies still depend on traditional network security solutions. To this end, many users are now using personally owned devices and connecting over unsecured home networks. What’s more, devices run a range of nonstandard IoT operating systems in addition to the many flavors of Microsoft Windows, Google Android, macOS, and others. Cybercriminals and hackers have noticed this trend and are using more sophisticated techniques, gaining access to more resources, and taking more targeted approaches to carry out attacks or run malware campaigns—all with the goal of stealing sensitive data. As such, endpoint security software has had to evolve rapidly to keep up with the threat environment, bring your own device (BYOD) culture, and the rise in remote work.[ Learn more](/resources/security-terms-glossary/what-is-endpoint-security)! ### Question: How Cloud-Based Endpoint Security Works ### Answer: Typically, endpoint security solutions function in one of two categories: prevention (before an attack) and response (after a cyberattack). Modern endpoint protection platforms (EPPs) such as endpoint detection and response incorporate both categories managed via a single, centralized interface. Endpoint security solutions deployed from the cloud bring security policies to users and provide threat protection and visibility that are always up to date. Where point products of the past could only provide fragmented protection and visibility over an organization’s remote endpoints, a cloud service allows for a more holistic view at the environment surrounding an endpoint, which makes it easier for security to diagnose a potential security issue. Using a management console through on-premises endpoint security solutions creates vulnerability. With such a technique, there are distinct gaps in visibility and, moreover, lapses in security coverage that leave you open to threats designed to exploit them. A cloud native architecture, on the other hand, provides a much quicker setup and implementation as well as more holistic protection against the new era of threats. And, like a SaaS solution, cloud endpoint protection lets you scale services according to your environment’s needs at any given time.

As with all endpoint protection tools, security professionals map threat hunting capabilities to identify, investigate, and remediate threats before they can infiltrate an endpoint and cause damage. - **Extended detection and response (XDR)** solutions go beyond typical EDR to unify protection across a larger list of security tools. Effectively, XDR provides threat protection wherever data travels—inbound or outbound—hence “extended.” - **Managed detection and response (MDR)** products provide the same security functions as EDR or XDR, but an organization using MDR will also benefit from management by a security operations center (SOC), giving the organization a team of threat hunters in its corner.

Here is a list of the main characteristics of typical endpoint security software: - Device protection - Network control - Application control - Data loss prevention - Browser protection - Encryption [Learn more](/resources/security-terms-glossary/what-is-endpoint-security)! ### Question: What Is the Difference Between Endpoint Security and a Firewall? ### Answer: Endpoint security tools typically monitor potential threat activity at the endpoint, whereas firewalls inspect web-based traffic that attempts to enter a network. Fundamentally, the question isn’t so much “endpoint security vs. firewall” but “endpoint security vs. network security.” To reiterate, network controls are fundamental to securing endpoints, especially in a remote setting, but in instances where endpoints are connecting directly to applications by forgoing the corporate network, there really isn’t much use for a firewall. In these instances, data and application controls are much more vital to an endpoint’s security. Firewalls were essential to endpoint security when employees went to the office and needed corporate network security to inspect traffic as they worked. Today, endpoints are everywhere and endpoints aren’t used the way they used to be—endpoint security methodologies have left the firewall behind. [Learn more](/resources/security-terms-glossary/what-is-endpoint-security)! ### Question: What Should I Consider When Implementing Zero Trust Endpoint Security in My Organization? ### Answer: Focus on verifying users and devices continuously, enforcing least-privileged access, and separating access with clear controls. Use tools like MFA and endpoint protection (e.g., EDR/XDR) to manage risks. Ensure visibility, keep systems updated with patches, and plan for monitoring and incident response. Compatibility with existing tools and clear remote-work policies are also key. ### Question: How is endpoint security different from network security? ### Answer: They key difference is that endpoint security protects individual devices, while network security focuses on the broader infrastructure and communication channels that connect those devices. Both work together to ensure comprehensive protection. ### Question: What are the common threats addressed by endpoint security? ### Answer: Endpoint security addresses a range of threats that target individual devices such as laptops, desktops, smartphones, IoT devices, and servers. Common Threats Addressed by Endpoint Security: - **Malware** - **Ransomware** - **Phishing Attacks** - **Zero-Day Exploits** - **Insider Threats** - **Credential Theft** - **Unsecured Devices** - **Fileless Attacks** ### Question: How is AI and machine learning advancing endpoint security? ### Answer: AI and machine learning (ML) are revolutionizing endpoint security by improving threat detection, response, and prevention. These technologies enhance traditional endpoint security tools, making them more effective at identifying and mitigating sophisticated attacks. Some examples include: - **Behavior-Based Threat Detection**: ML models analyze user and device behavior to detect anomalies, such as unusual logins or file executions, that may signal malicious activity. - **Predictive Analytics**: AI identifies patterns and predicts potential threats before they occur, reducing response time and improving prevention capabilities. - **Enhanced Malware Detection**: ML algorithms identify previously unknown malware strains by analyzing code characteristics, bypassing reliance on static signatures. ### Title: What Is Exact Data Match? | Meaning & Benefits - Zscaler ### Description: EDM is a data loss prevention (DLP) technique that finds and protects specific data values for the organization, not just general patterns. Read more. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-exact-data-match ### Question: What Is Exact Data Match (EDM)? ### Answer: Exact data match (EDM) is an advanced[ data loss prevention (DLP)](/resources/security-terms-glossary/what-is-cloud-dlp-data-loss-prevention) technique that finds specific data values that are important to the organization and need to be protected rather than finding general data patterns or formats only. For example, an organization can detect the exact match of a customer credit card number, rather than detecting only the pattern, to enhance detection accuracy and reduce false positives. [Learn more](/resources/security-terms-glossary/what-is-exact-data-match). ### Question: Benefits of EDM ### Answer: DLP already puts protocols in place to help organizations keep their data secure, but exact data match allows organizations to detect and protect specific data values. When it comes to selecting a quality platform, however, you should be on the lookout for certain features. Some of the benefits of an effective EDM platform include: 1. **Inline Inspection and Enforcement** 2. **Cloud Capacity** 3. **Granular Policy Control** [Learn more](/resources/security-terms-glossary/what-is-exact-data-match). ### Question: What Is EDM in Cybersecurity? ### Answer: The purpose of EDM, as with DLP, is to protect sensitive data such as personally identifiable information (PII) from exposure to the internet. Protecting such information becomes more difficult as organizations adopt cloud services, where managing security functions such as permissions, endpoint security, and remediation all increase an organization's risk of misconfiguration—the top cause of cloud data breaches. Exact data match is a method of data classification, which is a critical element of DLP. Typically, DLP systems use pattern matching to identify data that needs to be protected. A DLP system will monitor data such as credit card numbers, account numbers, Social Security numbers (SSNs), and so on depending on the types of records the administrator selects for protection and the policies attached to them. EDM helps these values stay protected on an exact basis rather than a tangential one, meaning that the value itself has its own security protocol rather than a group of values being treated as one. This schema will help security teams reduce the amount of false positives—or unnecessary notifications—they receive. [Learn more](/resources/security-terms-glossary/what-is-exact-data-match). ### Question: How Does Exact Data Match Work? ### Answer: EDM “fingerprints” sensitive data from structured data sources, such as databases or spreadsheets, and then watches for attempts to move the fingerprinted data to stop it from being shared or transferred inappropriately. If even one transaction appears suspicious, the DLP attached to EDM will close off access to all entries of that custom sensitive information type, such as a credit card number. It starts with plain text from a database or spreadsheet that contains the sensitive records. This data in these records is obfuscated, usually by hashing (i.e., data strings are algorithmically shortened and encrypted) and then stored within the DLP solution. The same algorithms are then applied to all outbound traffic. So, when traffic that is hashed matches the stored hashes, the transfer will be blocked or an alert will be triggered.

As the name suggests, FWaaS is delivered via the cloud; the main difference between the two is that on-premises firewalls struggle to scale and adapt to changing network demands and an evolving threat landscape. Because FWaaS is cloud native, it can do both, giving organizations a much more useful tool for securing data, keeping endpoints safe, and carrying out thorough security inspections. [Read more.](/resources/security-terms-glossary/what-is-firewall-as-a-service) ### Question: Why Do Companies Need FWaaS? ### Answer: As organizations embrace cloud infrastructure providers such as AWS to increase scalability, they still need to deliver enterprise firewall capabilities across the organization for all users and all locations. Unfortunately, NGFWs were architected more than a decade ago and aren’t designed to support cloud applications or the dynamic requirements of cloud computing in general. Their virtual firewall counterparts have many of the same limitations and challenges as traditional NGFW appliances, lessening their effectiveness against modern cyberattacks. It makes sense, then, that as your applications move to the cloud, your firewalls should move with them. [Read more.](/resources/security-terms-glossary/what-is-firewall-as-a-service) ### Question: How Does FWaaS Work? ### Answer: FWaaS allows organizations to establish secure local breakouts for all applications without security appliances to buy, deploy, or manage. Security capabilities, including full Layer 7 firewall, are delivered as a cloud service that scales elastically to handle SSL inspection, growing bandwidth and user demands, and cloud application traffic with long-lived connections. [Read more.](/resources/security-terms-glossary/what-is-firewall-as-a-service) ### Question: Benefits of FWaaS ### Answer: FWaaS provides multiple benefits over NGFWs, including: - **A proxy-based architecture** - **Cloud IPS** - **DNS security and control** - **Visibility and simplified management** - **Zero trust readiness** [Read more.](/resources/security-terms-glossary/what-is-firewall-as-a-service) ### Question: What Should I Consider When Choosing a Cloud-Based Firewall Service? ### Answer: When selecting a cloud-based firewall service, focus on the following key factors: - **Performance:** Look for global coverage, low latency, and scalability to support your users and locations. - **Security features:** Ensure TLS/SSL inspection, threat prevention, and zero trust policy enforcement are included. - **Integration:** Check compatibility with identity, endpoint, and SD-WAN systems for seamless operations. - **Management:** Prioritize centralized management, visibility, and compliance reporting. - **Reliability and cost:** Compare uptime SLAs, data privacy policies, logging practices, support quality, and pricing. ### Question: What are the key features of Firewall as a Service? ### Answer: Firewall as a Service (FWaaS) is a cloud-based firewall solution that provides advanced network security without the need for physical hardware. It ensures traffic filtering, access control, and threat detection across distributed environments, making it particularly suited for modern, cloud-focused organizations. Some key features are: - **Centralized Security** - **Scalability** - **Advanced Threat Detection** - **Global Accessibility** - **Policy Management** - **Integrations** - **Reduced On-Premise Infrastructure** ### Question: Can FWaaS replace VPNs or SD-WAN solutions? ### Answer: Firewall as a Service (FWaaS) has become a popular cloud-based security solution, but it doesn’t completely replace VPNs or SD-WANs in all scenarios. Here's a concise breakdown: - **FWaaS vs. VPNs:** FWaaS can replace traditional VPNs in many cases for secure remote access by using advanced features like Zero Trust Network Access (ZTNA) or software-defined perimeters. - **FWaaS vs. SD-WAN:** FWaaS doesn’t inherently replace SD-WAN but rather complements it by enhancing security for traffic management. ### Title: What Is Hybrid Cloud Security? | Definition and Key Concepts ### Description: Hybrid cloud security specifies the method of providing protection for enterprise data, applications, and resources in a hybrid cloud environment. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-hybrid-cloud-security ### Question: What Is Hybrid Cloud Security? ### Answer: Hybrid cloud security is the sum of the technologies and practices in place to protect an organization’s sensitive data, apps, and resources in a hybrid cloud environment that uses any combination of on-premises, private cloud, and public cloud platforms.

It is a crucial element of information security that helps organizations protect their sensitive data by restricting lateral movement and unauthorized access to business applications or resources. [Learn more](/resources/security-terms-glossary/what-is-least-privilege-access). ### Question: 3 Core Benefits of Least-Privileged Access ### Answer: The convergence of the three core elements with an effective ZTNA service forms the basis of a strong, resilient security posture for your organization, where: 1. **User accounts are always authenticated before access is granted** 2. **Devices are monitored and user access levels adapt based on security posture** 3. **App segmentation minimizes lateral movement, eliminating the need for complex firewall tuning** [Read more.](/resources/security-terms-glossary/what-is-least-privilege-access) ### Question: Least-Privileged Access and Zero Trust ### Answer: “**Least-privileged access**” can sound a lot like “**zero trust**,” and indeed, they’re closely related but still crucially different concepts. You can think of **least-privileged access** like a key card you give to each of your employees that’s uniquely coded to their job function. This lets you tailor access controls so most users can access common areas like Microsoft 365, but only some can access more sensitive material, such as financial information, HR data, and so on, reducing the risk of excessive permissions leading to data breaches. **Zero trust** takes this a step further, not granting trust simply because an employee has a unique key card. Before granting access, a zero trust policy establishes a user’s identity and full context for the connection request, such as the user’s device, their location, the application in question, and its content. This way—to extend the metaphor—another user can’t simply pick up a key card, take on its access rights, and start getting into places they don’t belong. [Read more](/resources/security-terms-glossary/what-is-least-privilege-access). ### Question: How modern Least-Privileged Access Works? ### Answer: Today, least-privileged access and zero trust are essentially inseparable, with a modern approach incorporating user identity authentication, device security posture, and user-to-app segmentation in its controls. Let’s examine these three core elements. 1. **User identity authentication** 2. **Device security posture** 3. **User-to-app segmentation** [Explore more](/resources/security-terms-glossary/what-is-least-privilege-access)! ### Question: 3 Steps to Implement Least-Privileged Access in your Organization ### Answer: 1. **Adopt an identity provider (IdP) service.** With the popularity of single sign-on services today, many organizations already leverage an IdP. 2. **Layer on a device posture service.** Combining device health monitoring with flexible device policy lowers the risk compromised endpoints pose to your critical systems and data. 3. **Enable a ZTNA service.** This allows you to eliminate both lateral access and internal firewalls with one technology. Some ZTNA services can be fully deployed in just a few hours. ### Title: What Is Malware? | Detection, Removal, & Protection -Zscaler ### Description: Malware is malicious software designed to steal sensitive data, encrypt it, take over system functions, or spread it to other devices, mostly to make a profit. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-malware ### Question: What Is Malware? ### Answer: Malware is malicious software designed to invade a computer system and take hostile action—such as stealing or encrypting sensitive information, taking over system functions, or spreading to other devices—most often for profit.

It will shield you from the latest social engineering attacks and ensure your defenses evolve to match the attackers. [Learn more](/resources/security-terms-glossary/what-is-malware). ### Question: Why Do Cybercriminals Use Malware? ### Answer: Threat actors use malware because it’s easy to deploy once they discover a vulnerability in a system’s defenses. 1. Trick users into handing over sensitive data 2. Install spyware to monitor activity on an endpoint 3. Install ransomware to lock systems or data until a ransom is paid 4. Steal sensitive information from a system 5. Gain access to financial information such as credit card numbers 6. Install adware to bombard users with pop-up ads 7. Install malicious software to disrupt, slow down, or damage computer systems 8. To accomplish all this, there are many different varieties of malware. Let’s take a closer look at some of the common types. [Learn more](/resources/security-terms-glossary/what-is-malware). ### Question: Types of Malware ### Answer: The most common types of malware infections are: 1. [**Ransomware**](/resources/security-terms-glossary/what-is-ransomware)**:** Malware that encrypts data and demands payment, usually in cryptocurrency, before providing a decryption key. A subvariety, double extortion ransomware attacks, steals the data in addition to encrypting it, gaining leverage to demand additional ransom, usually paid through bitcoin. 2. **Botnets:** A large number of “bot” systems—infected computers remotely controlled by threat actors—can be used for various purposes, such as rapidly spreading malware or performing denial of service attacks. 3. **Fileless malware:** Unlike most malware, fileless malware does not require users to download files. Instead, it uses legitimate tools in a malicious fashion to carry out an attack, such as by embedding malicious code in an operating system. 4. **Computer viruses:** With the ability to replicate themselves, viruses can spread quickly across hosts on a network and corrupt or delete data, which can affect the stability of applications or even whole systems. 5. **Trojan horse:** Criminals can piggyback malicious code within legitimate software or files, such as by disguising it inside an update, hiding it in a document, or through a scam such as malvertising which subsequently runs when the file or program is used. 6. **Rootkits:** These malicious software tools can give hackers access to and control over a device. Most rootkits affect software and operating systems, but some can also infect hardware and firmware. 7. **Spyware:** Threat actors can use spyware to covertly gather information about the activity on an endpoint, such as keystrokes (through the use of keyloggers), login details, website visits, and more. 8. **Adware:** Although it’s not always malicious, adware displays advertisements to encourage views and clicks that generate revenue. Invasive adware can harm user experience and affect system performance. [Learn more](/resources/security-terms-glossary/what-is-malware). ### Question: How to Know If You’re Infected with Malware? ### Answer: Systems that have been infected with malware exhibit some common symptoms. Look out for: - **Slow or faulty system operation:** Malware attacks tend to use extra system resources and create process conflicts, so if a computer is running or booting up more slowly than normal, or frequently freezing or crashing, it may be a sign of malware infection. - **Unwanted pop-up ads or security alerts:** Many computer systems and browsers automatically block pop-up ads. If a system is getting bogged down with ads, it could indicate a malware infection tampering with the blocking protocols. - **Ransom demands:** If a system is infected with ransomware, some or all files may be encrypted, with access to be restored only after a ransom payment. You may get a pop-up instructing you in how to make the payment.

Read more. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-multicloud ### Question: What Is Multicloud? ### Answer: Multicloud is a strategy in which an organization uses two or more cloud service providers or services to perform a variety of functions, such as cloud storage, cloud computing, security, or application support. By adopting a multicloud strategy as a part of a greater digital transformation, you can run public clouds and private clouds ([hybrid multicloud](/resources/security-terms-glossary/what-is-hybrid-cloud-security)). However, IT professionals generally use the term to describe using multiple clouds from different cloud providers. [Read more](/resources/security-terms-glossary/what-is-multicloud). ### Question: How Does a Multicloud Architecture Work? ### Answer: As organizations embrace cloud computing, they’re increasingly adopting multicloud environments due to the rise in remote work and the growing demand to have access to cloud services from anywhere, anytime, off the corporate network. A multicloud approach doesn’t mean cloud-only, though. Some organizations opt to keep some functions in their on-premises data centers or a private cloud while utilizing multiple cloud service providers for other purposes. Most often, organizations adopt multicloud solutions that comprise different infrastructure, platform, and software as a service (respectively IaaS, PaaS, and SaaS) providers. Additionally, a multicloud deployment is often an organization’s means of modernizing its ecosystem as it shifts toward a serverless architecture. [Read more](/resources/security-terms-glossary/what-is-multicloud). ### Question: Multicloud Service Providers ### Answer: Multicloud apps are all around us, coming from some of the biggest names in the tech world. Some of the most popular public cloud providers include: 1. Amazon Web Services (AWS) 2. Microsoft Azure 3. ServiceNow 4. Google Cloud Platform (GCP) 5. IBM Cloud 6. Oracle Cloud 7. Alibaba Cloud [Read more](/resources/security-terms-glossary/what-is-multicloud). ### Question: Multicloud Use Cases ### Answer: Beyond compatibility with a bevy of vendors, multicloud architectures offer high availability to support a wide variety of cloud-enabled technologies, such as: 1. APIs 2. Containers such as Kubernetes 3. Disaster recovery (DR) 4. Open source development 5. Microservices 6. DevOps Adopting multicloud gives businesses the agility to innovate at a much faster pace than with a single public cloud service or provider only. High performance and availability mean reduced downtime, and increased data management capacity opens the door for artificial intelligence and machine learning adoption, as well. [Read more](/resources/security-terms-glossary/what-is-multicloud). ### Question: What’s the Difference Between Hybrid Cloud and Multicloud? ### Answer: Where a hybrid cloud makes use of public and private cloud services, a multicloud architecture uses services from multiple public cloud providers at the same time. A hybrid cloud is suited for organizations that operate under strict compliance regulations, such as public sector, finance, or law firms. This is because private clouds are controlled by the organizations that deploy them. The organizations themselves bear the brunt of responsibility should they fall victim to a cyberattack, so a private cloud doesn’t come under the shared responsibility model. Furthermore, these clouds tend to be built on the basis of securing data. [Read more](/resources/security-terms-glossary/what-is-multicloud). ### Question: Benefits of Using a Multicloud Strategy? ### Answer: Employing a multicloud strategy can bring a host of benefits, including: 1. **Reduced cost:** Having more options allows you to compare prices and choose which option works for you. Plus, a multicloud strategy eliminates the need for set up and maintenance of physical data centers. 2. **Lower risks:** Having a distributed cloud infrastructure reduces your reliance on a single cloud provider, which enhances business continuity and reduces risks. Having clouds across different locations reduces the danger that an outage in one will bring work grinding to a halt. 3. **Compliance:** A multicloud strategy allows for increased compliance with policy and regulatory standards because each cloud infrastructure provider can monitor compliance individually. 4. **Scalability:** A multicloud strategy allows data and applications to reside in multiple locations worldwide, which in turn allows for exponential scalability as business needs grow and change. 5. **Improved user experience:** Having distributed locations through a multicloud strategy means they are closer to the user, reducing latency and improving user experience. Because you avoid single vendor lock-in, you have more choice and flexibility. [Read more](/resources/security-terms-glossary/what-is-multicloud). ### Question: Risks of Multicloud: ### Answer: 1. **Various rules:** Multiple providers will force you to contend with multiple rules and systems. It can become more complicated and time consuming for IT departments to monitor each one. 2. **Unfamiliarity:** With each cloud you adopt, you’ll have to become familiar with it and bring all employees up to speed. This can take time and effort. 3. **Security:** Monitoring all of these clouds can present some security challenges. For instance, it can be difficult to maintain a unified set of controls, which can cause security gaps. [Read more](/resources/security-terms-glossary/what-is-multicloud). ### Title: What is MPLS? (Multiprotocol Label Switching) | Zscaler ### Description: A multiprotocol label switching (MPLS) network determines the shortest path for packet forwarding by using labels rather than network addresses. Read more. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-multiprotocol-label-switching ### Question: What Is Multiprotocol Label Switching (MPLS)? ### Answer: Multiprotocol label switching (MPLS) is a method of wide area networking (WAN) that routes traffic using labels—not network addresses—to determine the shortest possible path for packet forwarding. It labels each data packet and controls the path it follows rather than sending it from router to router through packet switching. It’s intended to minimize downtime, improve quality of service (QoS), and ensure traffic moves as quickly as possible. [Read more](/resources/security-terms-glossary/what-is-multiprotocol-label-switching). ### Question: Benefits of MPLS ### Answer: Many consider MPLS to be a slightly older approach that provides an advantage over traditional IP routing, but is struggling against more agile and flexible options such as [SD-WAN](/resources/security-terms-glossary/what-is-sd-wan). Nevertheless, it does have a number of advantages. - **Improved scalability** - **Higher levels of performance** - **Reduced network traffic congestion** - **Better end user experiences** [Read more](/resources/security-terms-glossary/what-is-multiprotocol-label-switching). ### Question: What Is MPLS Used For? ### Answer: MPLS works by creating point-to-point paths that act as circuit-switched connections, but deliver layer 3 IP packets. In this sense, it is best for organizations that have remote branch offices in a large number of widespread locations that need data center access. At least, this was what it was best used for when workers were still going to offices. Many organizations would run MPLS within a virtual private network (VPN), either to create the aforementioned point-to-point path or for a private LAN service. It provided diversity in that it could be deployed irrespective of what underlying network protocols—ethernet, SDH, ATM, etc.—were being used. The forwarding decision would be unaffected because, again, it only mattered whether the label matched. [Read more](/resources/security-terms-glossary/what-is-multiprotocol-label-switching). ### Question: What Does MPLS Consist Of? ### Answer: MPLS has four unique mechanisms that improve connection quality and stability: 1. **The label:** There would be no MPLS without a label attached to each connection. 2. **Traffic class field:** This component prioritizes packets by QoS. 3. **Bottom-of-stack flag:** This tells an egress router that there are no further labels to be put on this connection. 4. **Time-to-live:** This refers to the number of hops data can make before being discarded. These four subparts make MPLS easier to manage than other less rigid methods of traffic forwarding. It can be likened to tracking a shipment or a package based on a tracking number rather than having to guess, for example, the license plate or VIN of the delivery truck. [Read more](/resources/security-terms-glossary/what-is-multiprotocol-label-switching). ### Question: How MPLS Networks Work for Cloud Adoption ### Answer: To enable MPLS to work in the cloud, you can supplement it with a number of technologies, including: - **Virtual routing services:** By using a cloud router on top of an MPLS appliance, you can leverage a software-defined network (SDN) to establish MPLS cloud connections. - **Offloading:** A direct-to-internet connection enables you to offload web traffic, allowing the MPLS to carry only the traffic heading to the office, unlocking spare capacity. - **SD-WAN:** SD-WAN augments MPLS with low-cost broadband internet links or replaces it with internet to base designs on the application and bandwidth needs. [Read more](/resources/security-terms-glossary/what-is-multiprotocol-label-switching). ### Question: Disadvantages of MPLS ### Answer: MPLS comes with a number of issues that are accentuated as you adopt remote work and the cloud: **Increased Complexity** Deploying and managing routers at every location is time-consuming, leads to security compromises, and limits your ability to respond to changing needs. **Poor User Experience** Backhauling traffic to centralized security appliances that weren’t designed to handle cloud app demands leave users unproductive and unhappy. **A Lack of Security** When users drop off your network and MPLS VPN, your security policies go blind and risk increases. You need consistent protection no matter how users connect. [Read more](/resources/security-terms-glossary/what-is-multiprotocol-label-switching). ### Question: MPLS vs. SD-WAN ### Answer: **MPLS** labeling can provide advantages over less-refined traffic routing methods of the past, but SD-WAN uses software-defined policies to select the best path to route traffic to the internet, cloud applications, and the data center. This makes it more useful for real-time applications such as UCaaS, VoIP, business intelligence, and so on. **SD-WAN** provides simpler provisioning and an increased breadth of traffic engineering configurations due to its software-defined construction. By that same token, SD-WAN offers much improved security over MPLS: software-defined policies established and enforced via the cloud help you secure network traffic wherever it’s coming from or going. SD-WAN offers a bevy of benefits over MPLS, but to inherit a full, cloud-delivered networking and security stack that provides great experiences and tight security, wherever they are, what you really need is a [secure access service edge (SASE)](/resources/security-terms-glossary/what-is-sase). ### Title: What is Network Security? | Types & Functionality | Zscaler ### Description: Network security refers to the combination of hardware and software designed to protect corporate data centers. Find out more! ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-network-security ### Question: What Is Network Security? ### Answer: Network security is the strategic combination of hardware and software designed to protect sensitive data in a computer network. Network access controls, intrusion detection, and many other types of network security functions work together to secure the environment against unauthorized access, data breaches, malware delivery, and other cyberattacks. [Read more](/resources/security-terms-glossary/what-is-network-security). ### Question: How Does Network Security Work? ### Answer: Network-based security has evolved as more network traffic traverses the internet rather than staying within a local network infrastructure. Today’s stack is in a security gateway, which monitors traffic moving to and from the internet. It includes an array of firewalls, intrusion prevention systems (IPS), sandboxes, URL filters, DNS filters, antivirus technology, data loss prevention (DLP) systems, and more that work together to keep external attacks from reaching data and intellectual property inside a network. [Read more](/resources/security-terms-glossary/what-is-network-security). ### Question: Why Is Network Security Important? ### Answer: Advanced network security solutions offer a more agile security approach in a world dominated by the cloud. Previously, many enterprises took the old “castle and moat” approach, using a firewall to provide perimeter-style security to a central corporate system. Herein, layers of defenses were built to prevent cybercriminals from breaching the perimeter, and if one layer fell, another was in place behind it. This worked well back when IT infrastructure was hosted on-site in a single server, but as employees became more mobile, they needed to be able to access systems and data from many different locations. This gave rise to virtual private networks (VPNs), which allow remote users to access the internal network. We’ll look at VPNs again in the next section. In the age of the cloud, the cyberthreat landscape and the needs of modern organizations have changed. With more frequent and sophisticated attacks, more stringent regulations, and far more data to process and secure, older models often can’t provide the agility, flexibility, and more advanced protection needed today. [Read more](/resources/security-terms-glossary/what-is-network-security). ### Question: What Types of Threats Does Network Security Prevent? ### Answer: The variety of network security tools on the market speaks to the breadth of the threat landscape. There are countless solutions designed to stop malware (e.g., spyware, ransomware, trojans), phishing, and other such threats. The key thing to note about legacy network security solutions ties back to the “castle and moat” approach—they’re largely built to protect networks against malicious activities from outside, with far less ability to protect from inside. We’ll take a closer look at that shortly. [Read more](/resources/security-terms-glossary/what-is-network-security). ### Question: Challenges of VPN? ### Answer: Much of the trouble with traditional network security lies in inefficient and insecure VPN infrastructure, because: - **VPNs don’t scale well.** - **VPNs don’t do security.** - **VPNs don’t do zero trust.** [Read more](/resources/security-terms-glossary/what-is-network-security). ### Question: From Network Security to Cloud Security ### Answer: Compared to traditional network security, the ideal cloud-based security solution provides: - **Faster user experience:** User traffic takes the shortest path to any app or internet destination. - **Superior security:** All internet traffic, including encrypted traffic, is inspected, with threat data correlated in real time. - **Reduced costs:** The need to constantly buy and maintain appliances disappears because cloud infrastructure is continually updated. - **Easier management:** A solution delivered as a service reduces the complexity of managing multiple devices. [Read more](/resources/security-terms-glossary/what-is-network-security). ### Question: How Does a Network Security Engineer Differ from a Cybersecurity Engineer? ### Answer: A network security engineer focuses on protecting an organization's network infrastructure, including firewalls, routers, switches, and network protocols, from threats. In contrast, a cybersecurity engineer takes a broader approach by securing all aspects of an organization's digital environment, including applications, endpoints, cloud services, and overall data security. ### Question: How Will the Future of Network Security Evolve with Cloud Technology? ### Answer: Network security will continue to evolve as cloud adoption grows to focus on scalable, cloud native security solutions, such as secure access service edge (SASE) and zero trust network access (ZTNA). These approaches have begun to replace traditional perimeter-based security, providing enhanced protection for users, devices, and applications directly from the cloud, regardless of location. ### Title: What is Network Segmentation? - Define & Use Cases | Zscaler ### Description: Network segmentation is the division of a network into multiple subnetworks to proactively manage cybersecurity and compliance. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-network-segmentation ### Question: What Is Network Segmentation? ### Answer: Network segmentation is the division of a network into multiple subnetworks—each with subnet-specific security policies and protocols—to attempt to prevent lateral movement. It’s one of the most widely used means of reducing a network's attack surface to combat cyberattacks. [Read more](/resources/security-terms-glossary/what-is-network-segmentation). ### Question: Types of Network Segmentation ### Answer: Traditionally, there have been two basic types of network segmentation: - **Physical segmentation** uses discrete firewalls, wiring, switches, and internet connections to separate parts of a network. This is the more expensive, less scalable type. - **Virtual segmentation**, also called logical segmentation, typically segments network traffic flows using virtual local area networks (VLANs), which can be protected by the same firewall. [Read more](/resources/security-terms-glossary/what-is-network-segmentation). ### Question: Network Segmentation vs. Microsegmentation ### Answer: Network segmentation is best used for north-south traffic, while microsegmentation adds a layer of protection for east-west traffic—server-to-server, app-to-server, web-to-server, and so on. A common analogy likens network segmentation to a castle’s moat and outer walls, whereas microsegmentation is the guards at the doors of each of the castle’s interior staterooms. ### Question: Network Segmentation Use Cases ### Answer: Well, in a few short words, it’s designed to help you: - **Stop lateral movement of external threats:** Segmenting parts of your network inside the perimeter means that even if your perimeter is breached, all your data is not immediately under threat. - **Stop lateral movement of internal threats:** Segmenting internal data by need for access (such as by department) reduces your risk of insider threats by making, for instance, financial data inaccessible to HR. - **Separate internal and guest networks:** By keeping guests in a guest segment, separate from the rest of your network, you can continue to offer them convenient connectivity without putting your internal devices and data at risk. - **Protect regulated data and stay compliant:** Storing sensitive data, such as payment card information, in a tightly access-restricted segment will better protect it from compromise and enable you to comply with data regulations.

This is the more expensive, less scalable type. - **Virtual segmentation**, also called logical segmentation, typically segments network traffic flows using virtual local area networks (VLANs), which can be protected by the same firewall. [Check more details here.](/resources/security-terms-glossary/what-is-network-segmentation) ### Question: Benefits of Network Segmentation ### Answer: - **Stronger cybersecurity for sensitive data** - **Less difficulty meeting regulatory compliance requirements** - **Simpler risk analysis and damage control** - **Safer endpoints and users** - **Reduced network congestion** [Read more](/resources/security-terms-glossary/what-is-network-segmentation). ### Question: Disadvantages of Network Segmentation ### Answer: - **Excessive trust** - **Misconfigurations** - **Work-intensive management** - **Complex controls** - **Scalability issues** - **Poor performance** [Read more](/resources/security-terms-glossary/what-is-network-segmentation). ### Question: Network Segmentation Best Practices ### Answer: - ##### **Don’t over-segment** - ##### **Perform regular audits** - ##### **Follow the principle of least privilege** - ##### **Limit third-party access** - ##### **Automate where you can** ### Question: Disadvantages of Traditional Segmentation ### Answer: A traditional approach leaves you dealing with: - **Excessive trust:** Because traditional firewall-based segmentation is designed to prevent attacks from outside, it can leave you vulnerable to insider threats. - **Misconfigurations:** VLANs are easy to misconfigure in today’s architectures, especially if you use third-party cloud providers and can’t change the infrastructure yourself. - **Work-intensive management:** Every new app, device, or change means updating firewall rules, and even mundane activities like vulnerability scanning require more resources. - **Complex controls:** Traditional methods lack fine-grained controls, making it complicated to define segmentation policy for remote workers, partners, customers, and so on. - **Scalability issues:** To handle network growth, you need to create smaller segments or upgrade existing ones, resulting in higher costs to scale and maintain. - **Poor performance:** Adding more network devices (e.g., firewalls, routers) has a compounding negative effect on your overall network performance. ### Question: Why Use Network Segmentation? ### Answer: Segmentation is a proactive mode of defense, offering key advantages over reactive security. With reactive security, teams first investigate a compromise, and then do damage control. It’s cumbersome and expensive, and it can still leave you grappling with data loss, compliance issues, and damage to your public image. It’s impossible to ignore: Organizations worldwide are still suffering data breaches. According to [Risk Based Security](https://www.riskbasedsecurity.com/2022/02/04/data-breach-report-2021-year-end/), 4,145 publicly disclosed breaches exposed more than 22 billion records in 2021 alone. That’s a clear indicator that instead of reacting to attacks, you should focus on prevention, addressing potential risks and vulnerabilities before they can be exploited. Network segmentation is among the most common ways to do this today. [Read more](/resources/security-terms-glossary/what-is-network-segmentation). ### Question: Network Segmentation Best Practices ### Answer: To help you learn the right way to implement and maintain an effective network segmentation model, here are five network segmentation best practices to live by: ### **1. Don’t over-segment** ### **2. Perform regular audits** ### **3. Follow the principle of least privilege** ### **4. Limit third-party access** ### **5. Automate where you can** ### Title: What Is Operational Technology (OT) Security? | Zscaler ### Description: As more OT systems are integrated with IT systems to drive automation, OT security becomes an important part of an overall cybersecurity strategy. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-operational-technology-ot-security ### Question: What Is Operational Technology (OT) Security? ### Answer: OT security is the measures and controls in place to protect OT systems—which use purpose-built software to automate industrial processes—against cybersecurity threats. As the convergence of information technology and OT drives greater automation and efficiency in industrial systems, OT security has become a requirement of critical infrastructure management. [Read more](/resources/security-terms-glossary/what-is-operational-technology-ot-security). ### Question: Why Is OT Cybersecurity Important? ### Answer: Years ago, OT assets weren’t connected to the internet, so they weren’t exposed to web-borne threats like malware, ransomware attacks, and hackers. Then, as digital transformation initiatives and IT-OT convergence expanded, many organizations added point solutions to their infrastructure to address specific issues, such as patching. This approach led to complex networks in which systems didn’t share information, and therefore couldn’t provide full visibility to those managing them. Industrial control systems (ICS)—the devices, controls, and networks that manage different industrial processes—are critical in maintaining operations and revenue streams. Compromise of common industrial systems, such as supervisory control and data acquisition (SCADA) systems, distributed control systems (DCS), and various customized applications, can have massive consequences for an organization, making them attractive targets for cyberattacks. [Read more](/resources/security-terms-glossary/what-is-operational-technology-ot-security). ### Question: What's the Difference Between IT and OT Security? ### Answer: While IT systems are designed for various uses for people, devices, and workloads, OT systems are instead purpose-built to automate specific industrial applications, presenting some key differences in how they are secured. One challenge lies in the technology life cycle. That of an OT system can span decades, whereas the life cycles of IT systems, such as laptops and servers, are often between four and six years. In practical terms, this means OT security measures often need to account for infrastructure that’s out of date, and may not even be possible to patch. Some OT systems are also highly regulated. For example, US Food and Drug Administration (FDA) regulations require the manufacturers of diagnostic machines to support them for 20 years from the date of deployment. OT systems are also managed by business units, and CIOs and CISOs are not typically responsible for procuring, managing, or securing these systems. OT and IT security do have something important in common, however: IT and OT both increasingly depend on connections to the internet or public networks. [Read more](/resources/security-terms-glossary/what-is-operational-technology-ot-security). ### Question: Operational Technology Security Best Practices ### Answer: Operational technologies vary widely, as do today’s available security solutions—but there are certain broad steps you should take as part of any effective OT security strategy: - **Map your environment.** Make sure your team can identify the digital locations of all devices in your network in real time. This will make it easier to understand you attack surface as well as pinpoint sources of issues. - **Monitor your entire ecosystem for suspicious activity.** Identifying unusual or otherwise anomalous activity in your network—including vendor and service provider traffic—is key to reducing security risks and maintaining a strong security posture. - **Adopt a zero trust framework.** Zero trust assumes any device, user, or network may be a threat until the entity is authenticated. Multifactor authentication is a core element of zero trust and vulnerability management. - **Enact** [**application-level microsegmentation**](/zpedia/what-is-microsegmentation). Unlike traditional flat [network segmentation](/resources/security-terms-glossary/what-is-network-segmentation), microsegmentation prevents users, including malicious insiders, from discovering applications they are not authorized to access. - **Leverage identity and access management.** Identity management and access controls are extremely important in IT environments, but absolutely paramount in OT environments, where compromises can be physically destructive, even dangerous to human safety. - **Educate your workforce.** Helping your employees understand the types of threats they can expect to face, and the potential vectors of those threats, can hugely reduce your overall risk.

It’s also a good idea for your organization to have a reporting mechanism through which staff can notify IT and security teams of new threats. These teams can then determine the next appropriate action, which can include reporting to service providers who may be able to patch the vulnerability, and in serious cases can even warrant reporting to an agency such as the US Federal Trade Commission. [Read more](/resources/security-terms-glossary/what-is-phishing). ### Question: How Does Phishing Affect Businesses? ### Answer: At the organizational level, the consequences of a successful phishing attack can be far-reaching and serious. Financial losses can stem from a compromised corporate bank account. Data loss can stem from phishing that leads to a ransomware attack. An organization can sustain major reputational damage from any breach of sensitive data that necessitates public disclosure. [Read more](/resources/security-terms-glossary/what-is-phishing). ### Question: How Do I Protect My Organization Against Phishing Attacks? ### Answer: Fortunately, most types of phishing can be stopped if you take the right precautions. That means: - **Use effective cybersecurity countermeasures.** - **Keep operating systems and browsers up to date.** - **Protect data with automatic backups.** - **Use advanced multifactor authentication (MFA)** - **Ensure your users are educated.** [Read more](/resources/security-terms-glossary/what-is-phishing). ### Question: What Are the Signs of Phishing? ### Answer: When it comes to phishing, the safest users are the ones who know how to avoid getting hooked. While a short summary is no substitute for focused security awareness training, here are a few key warning signs of having been targeted by a phishing campaign: - **Discrepancies in domain names:** Email addresses and web domains may have inconsistencies. For example, if you receive an email claiming to be from a well-known brand, the email address may not match it. - **Spelling errors:** Although phishing attacks have become much more effective, the messages still often contain spelling or grammatical mistakes. - **Unfamiliar greetings:** Sometimes, the style of a greeting or signoff can be a clue that something isn’t right. Take note if someone who always opens messages with “Hi!” suddenly says “Dear friend” instead. - **Short and sweet:** Phishing emails often keep information sparse, relying on ambiguity to throw off victims’ judgment. If too many important details are missing, it may be a sign of a phishing attempt. - **Unusual requests:** An email asking you to do something unusual, especially without explanation, is a big red flag. For example, a phishing attempt could claim to be from your IT team, asking you to download a file without specifying a reason.

Types, Prevention Strategies in 2025 ### Description: Discover what ransomware is, how it works, its impact on businesses, and top prevention strategies. Learn about types, examples, & solutions to protect your data in 2025. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-ransomware ### Question: What Is Ransomware? ### Answer: Ransomware is a sophisticated type of malware that encrypts and threatens to leak sensitive data, holding victims hostage until a ransom—often in cryptocurrency—is paid. It is one of the fastest-growing cyber threats impacting businesses and individuals alike. Ransomware attacks most often encrypt files, denying victims access to their data unless the victims pay by a deadline—after which they can lose access to the encrypted data permanently. Payment demanded for a decryption key can range from hundreds to millions of dollars. ### Question: The History of Ransomware and an Increase in Attacks ### Answer: Though cybercriminals have been using [ransomware attacks](/resources/security-terms-glossary/what-are-ransomware-attacks?_bt=649655743823&_bk=&_bm=&_bn=g&_bg=146095781443&utm_source=google&utm_medium=cpc&utm_campaign=google-ads-na&gclid=Cj0KCQjwnrmlBhDHARIsADJ5b_mLvBGsa5I8a953ZUVydf_ucLbO5XKGKsq4zdMffMTkJwJRB-3RNu0aAooaEALw_wcB) for more than 30 years, there has been a significant uptick in recent years. According to [the FBI](https://www.fbi.gov/news/stories/new-internet-scam/new-internet-scam), ransomware attacks started picking up in 2012, and show no sign of slowing. In the past, ransomware attacks that locked down a user’s files or computer could be easily reversed by a trained professional. But in recent years, these attacks have become more sophisticated and, in many cases, have left the victims with little choice but to pay the ransom demands or lose their data forever. A recent and notable change in many ransomware family variants is the addition of a data exfiltration feature. This new feature allows cybercriminals to exfiltrate sensitive data from victim organizations before encrypting the data. This exfiltrated data is like an insurance policy for attackers: even if the victims have good data backups, they’ll make the ransom payment to avoid having their data exposed. Due to the capacity limitations of legacy security technologies such as next-generation firewalls, most organizations do not have the ability to inspect all encrypted traffic traveling to and from endpoints. Attackers know this, so they are increasingly using encryption to hide their malicious code inside links and attachments. ### Question: How Ransomware Attacks Work: Phases and Methods Explained ### Answer: 1. **Spread via Phishing Emails and Infected Links:** Ransomware commonly spreads through phishing emails and ads with malicious links or websites embedded with malware. 2. **Disguised as Legitimate Communications:** These scams often mimic trusted organizations or known contacts, tricking victims into clicking malicious links or opening infected attachments. 3. **Targeting Individuals:** Ransomware locks personal documents, photos, and financial data, holding them hostage until a ransom is paid. 4. **Corporations as Attractive Targets:** Larger organizations are preferred targets because hackers can spread the ransomware from one compromised employee to the entire network, leading to higher stakes. 5. **Devastating Business Impact:** Ransomware disrupts operations, risks data exposure, and results in significant financial loss and reputational damage. ### Question: Types/Examples of Ransomware Attacks ### Answer: - **GandCrab:** According to VirusTotal’s [Ransomware in Global Context](https://storage.googleapis.com/vtpublic/vt-ransomware-report-2021.pdf) report, this family has been the most prevalent in ransomware attacks since 2020, with 78.5% of the samples taken for the report coming from this family. - **REvil/Sodinokibi:** This group is notorious for stealing large quantities of information in the legal and entertainment industries as well as the public sector. They first made headlines in May 2020, but carried out successive attacks each month from March to October 2021, including the Kaseya VSA attack. - **WannaCry:** A ransomware cryptoworm that targets the Microsoft Windows operating system, it has impacted more than 300,000 systems (and counting) worldwide since its release in 2017. - [**Ryuk**](https://blogs/security-research/examining-ryuk-ransomware)**:** This strain of ransomware has been tied to a number of groups that have impacted industries such as healthcare, the public sector, and education, particularly US school systems. - **Evil Corp:** This group is responsible for Dridex, a type of malware deployed through phishing emails that’s known for stealing banking credentials. It has since been associated with other types of ransomware such as WastedLocker, BitPaymer, and DoppelPaymer. These are but a few of the most noteworthy examples of ransomware; there are new ransomware variants being born every day, each one designed to attack a variety of vectors. So, how safe are you against ransomware attacks? Run a free [Internet Threat Exposure Analysis](https://securitypreview.zscaler.com/) to find out. ### Question: What Is Ransomware as a Service (RaaS) and Why Is It Growing? ### Answer: Ransomware as a service is a byproduct of ransomware's popularity and success. Like many legal SaaS offerings, RaaS tools are usually subscription-based. They're often inexpensive and readily available on the dark web, providing a platform for anyone—even those without programming skills—to launch an attack. If a RaaS attack is successful, the ransom money is divided between the service provider, the coder, and the subscriber. ### Question: Best Practices to Prevent Ransomware Attacks and Secure Sensitive Data ### Answer: - Back up computers, so you can restore your system to its previous state using your backups. - Store backups separately, such as on an external hard drive or in the cloud, so they cannot be accessed from a network. - Update and patch computers to negate vulnerabilities in applications and operating systems. - Train employees with ongoing, mandatory cybersecurity awareness sessions to ensure they are aware of current cyberthreats and security best practices. Be sure they are cautious with email—even from senders they know, verifying the sender’s legitimacy before opening any email attachments or clicking links. - Create a continuity plan for remediation in the event your organization becomes the victim of a ransomware attack. - Use anti-malware and/or antivirus software to assist users in stopping threats before they can wreak havoc. - Implement strong authentication measures using zero trust to prevent hackers from breaching your network, applications, and data. ### Question: Advanced Technological Defenses Against Ransomware ### Answer: 1. **Cloud-Based Security Posture:** Adopt a security framework built natively in the cloud to protect users, applications, and sensitive data, regardless of device or connection location. 2. **AI-Driven Sandbox Quarantine:** Use advanced AI technology to quarantine and inspect suspicious content before delivering it to recipients, minimizing potential threats. 3. **SSL/TLS Traffic Inspection:** Inspect all encrypted traffic to detect and eliminate hidden threats within SSL/TLS connections. 4. **Always-On Protection:** Ensure continuous protection for users, whether they are on or off the corporate network, for comprehensive defense. 5. **Universal Security Defense:** No organization is immune to ransomware—invest in a dedicated security strategy to avoid becoming the next victim of a costly and disruptive attack. ### Question: How Do Ransomware Attacks Work? ### Answer: A typical ransomware attack happens in four phases. Delivery—a phishing email is sent to entice a user to open it, launching an attack. Exploitation—the attack spreads once the malware has been successfully loaded. Callback—the malware payload attempts to communicate with its command-and-control (C2) servers where the stolen data is sent. Detonation—the malware steals data and installs the ransomware, encrypting and locking the system or data so an individual or company can’t access it. ### Question: Should You Pay the Ransom? ### Answer: Unfortunately, there’s no definite correct answer. Gartner analyst Paul Proctor effectively asserts that it’s up to you: “It comes down to when business outcomes are impacted by the lack of the stolen data. The organization must weigh if the business loss is worth rolling the dice on making a payment.” ### Question: What Are the Effects of Ransomware on Businesses? ### Answer: You only need to check the news every other day to understand how ransomware is impacting businesses across all industries. But, in case you’ve been living under a rock, here are some of the ways which ransomware can hurt your bottom line: You can (and will) lose money and/or data, your business’ reputation will suffer, and you may even face legal repercussions. ### Question: What Are the Most Effective Strategies to Mitigate Ransomware Attacks? ### Answer: The most effective strategies to mitigate ransomware attacks include: - Maintain robust and secure data backups, and keep systems and software up to date. - Train your employees to recognize phishing attempts and other forms of social engineering. - Adopt a zero trust architecture to reduce the attack surface, prevent compromise, stop lateral movement, and block data exfiltration. - Develop an incident response plan to reduce damage and speed up recovery in the event of a successful attack. ### Question: Can Antivirus Help with Ransomware? ### Answer: Antivirus software can help block some ransomware, especially known malware strains. However, modern advanced ransomware often bypasses traditional antivirus. To strengthen defenses, organizations should pair antivirus with real-time traffic inspection, AI-driven detection, and proactive threat hunting. A layered approach combining modern tools and practices is essential for effectively countering ransomware. ### Question: What Are Some Recent Ransomware Attack Examples? ### Answer: Some noteworthy ransomware attacks from the last decade include: - **WannaCry:** A 2017 cryptoworm targeting Windows that hit over 300,000 systems globally. - **REvil:** Known for attacks in legal and public sectors, including the Kaseya VSA breach. - **Colonial Pipeline (DarkSide):** A 2021 attack disrupting US fuel supplies. - **LockBit:** The most active ransomware strain of 2023, impacting more than 800 victims. ### Question: Are There New Trends in Ransomware Detection That I Should Know About? ### Answer: Ransomware detection is benefiting from AI and machine learning, which spot behavioral patterns, anomalies, and emerging threats faster. These tools analyze encrypted traffic, phishing lures, and attack vectors. Encryption-less ransomware and "double extortion" models remain significant threats. Organizations should implement real-time traffic inspection and automated sandbox solutions to counter these evolving tactics. ### Question: How Can Organizations Improve Their Ransomware Detection Methods? ### Answer: Organizations can enhance their ransomware detection by combining technology with a proactive approach: - Deploy AI-driven tools to analyze traffic and detect unusual activity. - Leverage a cloud native zero trust architecture to inspect all encrypted traffic for hidden threats. - Use sandboxes to quarantine and analyze suspicious files. - Train staff to recognize and report potential phishing attempts. ### Title: What Is Remote Browser Isolation? Need & Benefits | Zscaler ### Description: Remote browser isolation is an advanced cybersecurity technique that provides an additional layer of protection for users and organizations. Read more. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-remote-browser-isolation ### Question: What Is Remote Browser Isolation? ### Answer: Remote browser isolation (RBI) is a web security technology that neutralizes online threats by hosting users’ web browsing sessions on a remote server instead of the user’s endpoint device. RBI separates web content from the user’s device to reduce its attack surface. The endpoint receives a pixel-based stream of a webpage or app—not the active content. The user’s experience is unaffected, and hidden malicious code can’t reach them. [Learn more](/resources/security-terms-glossary/what-is-remote-browser-isolation). ### Question: How Does Remote Browser Isolation Technology Work? ### Answer: Here’s a quick summary of how remote browser isolation works: - A user tries to access a potentially malicious webpage - The request is evaluated against defined policies, and if there’s a match, the platform creates an isolated browser session - The platform connects to the webpage and loads the content onto the remote isolated browser - Rendered web content is streamed to the end user’s native browser as pixels over an HTML5 canvas [Read more](/resources/security-terms-glossary/what-is-remote-browser-isolation). ### Question: The Need for Remote Browser Isolation (RBI) ### Answer: RBI is not network security. Rather, it makes it possible for employees to access the internet without posing a risk to their safety or your network. Remote browser isolation solutions enable safe access to web content by separating a user’s endpoint device and their local network and infrastructure from the actual web applications and browsing activity. RBI helps you stop attacks from advanced threats and protect sensitive data by creating a “browser sandbox” between the user and potentially risky web content. [Read more](/resources/security-terms-glossary/what-is-remote-browser-isolation). ### Question: Benefits of Remote Browser Isolation (RBI) ### Answer: To make web browsing safer, remote browser isolation: - ##### **Enables secure access** - ##### **Protects sensitive data** - ##### **Removes the threat of data exfiltration** - ##### **Allows more open internet policies** [Read more](/resources/security-terms-glossary/what-is-remote-browser-isolation). ### Question: How Does Remote Browser Isolation Fit into a Zero Trust Security Architecture? ### Answer: [Zero trust](/resources/security-terms-glossary/what-is-zero-trust) is built on the premise that all network and user activity should be untrusted by default. With the right technology, your business can simultaneously leverage a zero trust approach with RBI to separate users from sessions and stop accidental and malicious data leakage. Enabling zero trust for RBI lets you extend the definition of zero trust to everything users do on the internet and in SaaS and private apps, up to and including a cloud-hosted RBI session.

Explore this ultimate resource now. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-sd-wan ### Question: What Is SD-WAN? ### Answer: Software-defined wide area networking (SD-WAN) is an approach to connecting globally distributed locations by intelligently routing traffic based on policies and real-time analytics. It optimizes WAN connectivity for faster application performance and improved reliability. As a result, organizations can reduce costs, bolster security, and streamline network operations without sacrificing the agility required in today’s rapidly evolving IT landscape.. [Read more](/resources/security-terms-glossary/what-is-sd-wan). ### Question: What’s the Difference Between SD-WAN vs. Traditional WAN? ### Answer: | **Traditional WAN** | **SD-WAN** | |---|---| | - Legacy data center-centric approach | - Modern software-defined networking approach | | - Lengthy deployment and configuration | - Fast, simple deployment and configuration | | - Rigid, complex, cumbersome, and expensive | - Flexible, simple, easy to manage, and affordable | | - Difficult to integrate with SWG, firewalls, etc. | - Easy to integrate with SWG, firewalls, etc. | | - MPLS connections are private but not secure | - Virtual tunnel overlays are encrypted end to end | ### Question: How SD-WAN Works? ### Answer: In essence, SD-WAN technology introduces an abstraction layer between the physical infrastructure and the control mechanisms that direct network traffic. This separation enables centralized policy management, where administrators can rapidly push configuration changes to all sites. By doing so, SD-WAN offers greater flexibility for organizations to route traffic via multiple transport options—whether broadband, 4G/5G, or [multiprotocol label switching (MPLS)](/resources/security-terms-glossary/what-is-multiprotocol-label-switching) circuits—based on application-specific needs. The outcome is a dynamic, cost-effective WAN that balances performance priorities with security essentials. To understand how SD-WAN works on a deeper level, it helps to think of each site, such as a branch office, as connected through virtual tunnels that the central controller oversees. The controller monitors traffic flows in real time and makes decisions on which path best supports each kind of traffic. With this method, MPLS no longer stands alone as the sole carrier of critical data; other links become equally viable for maintaining or even improving network resilience when it comes to demanding applications or shifting workloads. [Read more](/resources/security-terms-glossary/what-is-sd-wan). ### Question: Why Is SD-WAN Important? ### Answer: Traditional WAN architectures fall short as organizations migrate more of their apps and data to the public cloud. Security is more important than ever, but backhauling traffic from remote users and branch offices over private networks—such as [MPLS](/resources/security-terms-glossary/what-is-multiprotocol-label-switching#:~:text=Multiprotocol%20label%20switching%20(MPLS)%20is,possible%20path%20for%20packet%20forwarding.) or [VPN](/resources/security-terms-glossary/what-is-remote-access-vpn#:~:text=A%20remote%20access%20virtual%20private,through%20an%20IPsec%20encrypted%20tunnel.)—to a centralized internet gateway and back again introduces latency and creates a poor user experience. Hybrid WANs can see to some of these issues, and they’re still a compelling alternative to the expense and inflexibility of traditional WAN connections. However, they don’t necessarily use SDN technology—in which case they can’t dynamically route traffic to ensure the best path. This alone puts hybrid WAN at a distinct disadvantage compared to SD-WAN. By taking advantage of software-defined policies to determine optimal paths, SD-WAN makes it easy to establish local internet breakouts, which bring cloud-based applications and other cloud services as close to users as possible. What’s more, combining SD-WAN with cloud-delivered security allows an organization to bring policy as close as possible. We’ll look at that in more detail shortly. [Read more](/resources/security-terms-glossary/what-is-sd-wan). ### Question: Benefits of SD-WAN ### Answer: SD-WAN empowers organizations to transform their network infrastructure for smoother performance and higher cost effectiveness. Below are five advantages that highlight the impact of adopting a software-defined WAN solution: - **Improved application experience:** Prioritizes critical apps so they function smoothly even during peak usage. - **Lower operational costs:** Offers flexibility with broadband links and reduces reliance on expensive MPLS connections. - **Increased agility and scalability:** Deploys new sites or makes changes rapidly through centralized provisioning. - **Enhanced security posture:** Encrypts data end-to-end and integrates seamlessly with advanced security services. - **Streamlined** [**network operations:**](/partners/technology/operations#ndr) Simplifies management through a single interface while automating routine tasks.

To support today's agile operations, these are delivered as a service from the cloud and can be managed centrally. [Read more](/resources/security-terms-glossary/what-is-sase). ### Question: What does SASE mean? ### Answer: [SASE](/resources/security-terms-glossary/what-is-sase) (pronounced “sassy”) refers to the whole framework, not a specific technology. In its 2019 report "**The Future of Network Security is in the Cloud**," Gartner defined the SASE framework as a cloud-based cybersecurity solution that offers “comprehensive WAN capabilities with comprehensive network security functions (such as SWG, CASB, FWaaS, and ZTNA) to support the dynamic secure access needs of digital enterprises.” [Read more](/resources/security-terms-glossary/what-is-sase). ### Question: How does SASE work? ### Answer: A SASE architecture combines a [software-defined wide area network (SD-WAN)](/products-and-solutions/zero-trust-sd-wan) or other WAN with multiple security capabilities (e.g., cloud access security brokers, anti-malware), securing your network traffic as the sum of those functions. Legacy approaches to inspection and verification, such as forwarding traffic through a multiprotocol label switching (MPLS) service to firewalls in your data center, are effective if that's where your users are. Today, though, with so many users in remote locations, home offices, and so on, this "hairpinning"—forwarding remote user traffic to your data center, inspecting it, and then sending it back again—tends to reduce productivity and hurt the end user experience. What makes SASE stand out from point solutions and other secure networking strategies is that it's both secure and direct. Rather than relying on your data center security, traffic from your users' devices is inspected at a nearby point of presence (the enforcement point) and sent to its destination from there. This means more efficient access to applications and data, making it the far better option for protecting distributed workforces and data in the cloud.

Discover Cloud-Based SSE Solutions for Advanced Protection. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-security-service-edge-sse ### Question: What is Security Service Edge (SSE)? ### Answer: Security service edge (SSE), as defined by Gartner, is a convergence of network security services delivered from a purpose-built cloud platform. SSE can be considered a subset of the secure access service edge (SASE) framework with its architecture squarely focused on security services. SSE core services include secure web gateway (SWG), zero trust network access (ZTNA), cloud access security broker (CASB), and firewall as a service (FWaaS). [Read more](/resources/security-terms-glossary/what-is-security-service-edge-sse). ### Question: SSE Benefits ### Answer: - **Stronger, consistent cloud-based security** that extends protection across HQ and out to branch offices and remote/mobile users - **Optimized, low-latency network and security performance**, because traffic isn’t hairpinned to a central data center for enforcement - **Scalability to adapt to an organization’s shifting needs**, such as adoption of new cloud services and growth or movement of the workforce - **Streamlined security and networking management** through a centralized, cloud-delivered platform for critical security services - **More predictable costs and reduced operational overhead** through minimizing the need for on-premises hardware deployments ### Question: Why Security Service Edge (SSE) is Important? ### Answer: SSE is growing rapidly as a solution to fundamental challenges in the cloud, secure edge computing, remote work, and digital transformation. As organizations adopt infrastructure and software as a service (IaaS, SaaS) offerings and cloud apps, their data becomes more distributed outside their on-premises data centers. In addition, many organizations’ users are increasingly mobile and remote, connecting to apps and data from everywhere, over any connection.[ Explore more](/resources/security-terms-glossary/what-is-security-service-edge-sse). ### Question: What is Secure Access Service Edge (SASE) vs. Security Service Edge (SSE) ### Answer: In the SASE framework, network and security services should be consumed through a unified, cloud-delivered approach. The networking and security aspects of SASE solutions focus on improving the user-to-cloud-app experience while reducing costs and complexity. You can look at a SASE platform in two slices. The SSE slice focuses on unifying all security services, including SWG, CASB, and ZTNA. The other, the WAN edge slice, focuses on doing so for networking services, including software-defined wide area networking (SD-WAN), WAN optimization, quality of service (QoS), and other means of improving routing to cloud apps.

Learn more! ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-shadow-it ### Question: What Is Shadow IT? ### Answer: Shadow IT is a term for SaaS applications employees access and use without the knowledge or permission of their information technology departments. Such applications aren’t inherently flawed or dangerous—“shadow IT” simply means an app is being used without IT’s explicit approval or oversight, which increases risk for an organization. [Learn more](/resources/security-terms-glossary/what-is-shadow-it). ### Question: What Are the Security Risks of Shadow IT? ### Answer: Shadow IT can lead to cybersecurity concerns, misuse of IT resources, and ultimately, inefficiencies in productivity as well as headaches for IT professionals. Some of the most significant risks include: 1. ##### **Data exposure** 2. ##### **Productivity loss** 3. ##### **Malware** 4. ##### **Vulnerabilities** 5. ##### **Noncompliance** [Learn more](/resources/security-terms-glossary/what-is-shadow-it). ### Question: Why Does Shadow IT Occur? ### Answer: Shadow IT typically occurs when an employee has a particular job to do and a preferred way to get it done. The employee may have previous experience with a specific app, or simply prefer its functionality over the apps sanctioned by the organization. Or perhaps the organization doesn’t have a sanctioned option at all in an app category the employee needs, be it messaging, file sharing (e.g., Dropbox), or others. Shadow IT also occurs when an employee accesses an unsanctioned application used by a third party, such as a: - Supplier - Technology partner - Channel partner Then, of course, in many instances, shadow IT apps are simply for employees’ entertainment or other personal purposes. In all these cases, the use of unsanctioned applications creates IT security challenges because IT teams have no visibility or control over these apps. [Learn more](/resources/security-terms-glossary/what-is-shadow-it). ### Question: How Do You Control Shadow IT? ### Answer: The first thing an IT department must do is discover all the unsanctioned applications running throughout the distributed organization, and then bring a[ cloud access security broker (CASB)](/resources/security-terms-glossary/what-is-cloud-access-security-broker) into the picture. A CASB provides tremendous security value when it comes to shadow IT blocking in management. CASBs: - Ingest logs and workflows from network devices such as firewalls and proxies - Comb these logs and workflows for apps - Detail uncovered apps’ security attributes as well as whether or not they require additional security measures.

Spear phishing attacks use publicly available or stolen personal data and other information specific to their targets to make their deception more convincing than other broader phishing techniques. [Read more](/resources/security-terms-glossary/what-is-spear-phishing). ### Question: Types of Spear Phishing ### Answer: There’s a litany of different techniques and types of phishing scams out there. Let’s look at a few techniques frequently seen in spear phishing campaigns: - **Angler phishing** - **Business email compromise (BEC)** - **Whaling** - **CEO fraud** - **Clone phishing** [Read more](/resources/security-terms-glossary/what-is-spear-phishing). ### Question: How Do Spear Phishing Attacks Work? ### Answer: Spear phishing starts as a message, such as an email, that seems to be from a trusted source. Cybercriminals use information they know about their target to make the message appear genuine, and then ask the recipient to take some action, such as opening an attached file or following a benign-looking malicious link. For example, an email might copy visual elements from the target’s bank and ask the target to verify a transaction or check an important notification. The target follows a link in the email that takes them to a bogus website that looks and feels like the bank’s real site, where a prompt asks for login credentials, confirmation of a credit card number, or similar. Some attacks employ impersonation, appearing as emails from someone in the target’s address book—a friend, family member, or colleague, for instance. An email from a “friend” might ask the recipient to look at a funny link or download a useful file. Because the target thinks they know the sender, they’re less likely to notice warning signs or suspect a scam. [Read more](/resources/security-terms-glossary/what-is-spear-phishing). ### Question: What Are the Targets of Spear Phishing? ### Answer: ### **Individuals** Anyone can become a target of spear phishing attacks. If phishers get hold of someone’s personal details, especially confidential information, they can use it to make their attack more convincing. People with important positions in their organizations are generally at greater risk, as they’re often responsible for more sensitive data. ### **Businesses** Infiltrating a company’s system can give cybercriminals access to huge amounts of valuable sensitive information, and data breaches—especially in the financial and technology sectors—can cost companies millions in recovery costs, potential fines, and loss of customer trust. The massive shift to the cloud and remote work has made businesses even more vulnerable, as distributed IT environments introduce many more possible vectors of attack. [Read more](/resources/security-terms-glossary/what-is-spear-phishing). ### Question: How to Defend Against a Spear Phishing Attack or Best Practices ### Answer: - ##### **Keep operating systems and browsers up to date** - ##### **Protect data with automatic backups.** - ##### **Use multifactor authentication (MFA).** - ##### **Follow tight security protocols.** - ##### **Ensure your users are educated.** ### Title: What Is SSL Decryption? | Define & Core Concepts | Zscaler ### Description: SSL decryption allows organizations to inspect encrypted traffic to confirm that it contains no malicious content or malware. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-ssl-decryption ### Question: What is SSL Decryption? ### Answer: SSL decryption is the process of unscrambling encrypted traffic to check it for cyberthreats as part of a full SSL inspection procedure. It’s a vital network security capability for modern organizations since[ the overwhelming majority of web traffic is now encrypted](https://transparencyreport.google.com/https/overview?hl=en), and some cybersecurity analysts estimate more than 90% of malware may now hide in encrypted channels. [Read more](/resources/security-terms-glossary/what-is-ssl-decryption). ### Question: Benefits of SSL Decryption ### Answer: Implementing SSL decryption and inspection helps today’s organizations keep their end users, customers, and data safe, with the ability to: - **Prevent data breaches by finding hidden malware** and stopping hackers from sneaking past defenses - **See and understand what employees are sending** outside of the organization, intentionally or accidentally - **Meet regulatory compliance requirements**, ensuring employees aren’t putting confidential data at risk - **Support a multilayered defense strategy** that keeps the entire organization secure [Read more](/resources/security-terms-glossary/what-is-ssl-decryption). ### Question: Why Is SSL Decryption Important? ### Answer: With the growing popularity of the cloud and SaaS apps, it’s become more likely that a given file or string of data will traverse the internet at some point. If that data is confidential or sensitive, it could be a target. Encryption, therefore, is essential to keeping people and data safe. That’s why most browsers, websites, and cloud apps today encrypt outgoing data as well as exchange that data over encrypted connections. Of course, it works both ways—if sensitive data can use encryption to hide, then threats can, too. This makes effective SSL decryption equally essential as it enables an organization to fully inspect the contents of decrypted traffic before either blocking it or re-encrypting it so that it can continue on its way. [Read more](/resources/security-terms-glossary/what-is-ssl-decryption). ### Question: SSL Decryption Best Practices ### Answer: The need to implement an SSL decryption and inspection function to protect your organization has become too great to ignore. Even so, there are important things to consider—some more technical than others—as you deploy SSL inspection: - Start with a small location or test lab to ensure your team understands the feature, and that it works as intended, before enabling it more broadly. - To reduce troubleshooting, consider updating your end user notifications to inform users of the new SSL inspection policy. - (Optional) When defining SSL inspection policy, create a list of URLs and URL categories as well as cloud apps and cloud app categories for which SSL transactions will not be decrypted. - At first, only enable inspection for risky categories—adult content and gambling, for instance, or those that pose privacy or liability risks. Then, when ready, enable inspection for all URL categories except finance and health to allay privacy concerns. - Take note of applications your organization uses that leverage [certificate pinning](https://help.zscaler.com/zia/public-key-pinning-and-zscaler), where the application will accept only one specific client certificate. These apps might not work with SSL inspection, so you’ll need to include them in the list of what not to decrypt. - Enable user authentication to allow your SSL inspection service to apply user policies. [Read more](/resources/security-terms-glossary/what-is-ssl-decryption). ### Title: What Is SSL Inspection? | Benefits & Need | Zscaler ### Description: SSL inspection is the process of intercepting and reviewing SSL-encrypted internet communication between the client and the server. Learn more about it! ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-ssl-inspection ### Question: What Is SSL Inspection? ### Answer: [**SSL inspection**](/products-and-solutions/ssl-inspection) is the process of intercepting and reviewing SSL-encrypted internet communication between the client and the server. The inspection of SSL traffic has become critically important as the vast majority of internet traffic is SSL encrypted, including malicious content. [Read more.](/resources/security-terms-glossary/what-is-ssl-inspection) ### Question: SSL vs. TLS ### Answer: Time for a disambiguation. Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are both cryptographic protocols that govern encryption and transmission of data between two points. So, what’s the difference? The now-defunct Netscape developed SSL in the mid-1990s, releasing SSL 3.0 in late 1996. TLS 1.0, based on an improved version of SSL 3.0, came about in 1999. TLS 1.3, released by the Internet Engineering Task Force (IETF) in 2018, is the most recent and secure version as of this writing. Today, SSL is no longer developed or supported—by 2015, the IETF had[ declared all versions of SSL deprecated](https://datatracker.ietf.org/doc/html/rfc7568) due to vulnerabilities (e.g., to man in the middle attacks) and lack of critical security features. Despite this and decades of change, outside of a strictly technical sense, most people still say “SSL” as a catch-all for cryptographic protocols. In other words, when you see SSL, TLS, SSL/TLS, HTTPS, and so on, they all mean the same thing most of the time. For the purposes of this article, we’ll clarify as needed.

Long regarded as a key framework for ICS [network segmentation](/resources/security-terms-glossary/what-is-network-segmentation) to protect operational technology (OT) from malware and other attacks, the model persists alongside the rise of edge computing and direct-to-cloud connectivity. **[Read more.](/resources/security-terms-glossary/what-is-purdue-model-ics-security)** ### Question: What’s the Purpose of the Purdue Model? ### Answer: The model shows how the typical elements of an ICS architecture interconnect, dividing them into six zones that contain information technology (IT) and OT systems. Implemented correctly, it helps establish an “air gap” between ICS/OT and IT systems, isolating them so an organization can enforce effective access controls without hindering business. **[Read more.](/resources/security-terms-glossary/what-is-purdue-model-ics-security)** ### Question: Zones of the Purdue Model ### Answer: OT systems occupy the lower levels of the model while IT systems occupy the upper levels, with a “demilitarized zone” of convergence between them. Let’s take a look at each of the zones in the Purdue reference model, top to bottom: ### **Level 4/5: Enterprise Zone** ### **Level 3.5: Demilitarized Zone (DMZ)** ### **Level 3: Manufacturing Operations Systems Zone** ### **Level 2: Control Systems Zone** ### **Level 1: Intelligent Devices Zone** ### **Level 0: Physical Process Zone** **[Read more.](/resources/security-terms-glossary/what-is-purdue-model-ics-security)** ### Question: Cybersecurity Challenges Unique to ICS ### Answer: Let’s take a look at a few of those challenges: - **The air gap doesn’t work anymore.** The rise of IoT and cloud adoption across the industrial value chain has made many industrial networks so integrated that the traditional air gap simply isn’t effective. - **ICS devices were built to last, not to evolve.** Stringent uptime requirements of many industrial devices make it difficult, costly, or risky to update or replace them, leaving many CIM devices vulnerable to modern attacks, yet still connected to the wider network. - **IT-OT convergence and new technologies increase risk.** As digital transformation breaks down IT-OT barriers, advancements in networking and data analytics reshape processes, and new sophisticated cyberattacks appear, ICS frameworks are slow to adapt. - **Many ICS network owners hesitate to adopt zero trust.** Concerns over downtime causing lost revenue, disrupting infrastructure, or even endangering people’s safety make industrial operators uncertain about potential tradeoffs in costs and complexity, even as zero trust remains the most effective strategy for securing modern networks. [Read more.](/resources/security-terms-glossary/what-is-purdue-model-ics-security) ### Question: The Need for Zero Trust in ICS ### Answer: [Zero trust](/resources/security-terms-glossary/what-is-zero-trust) can simplify security for OT environments and solve key challenges such as secure remote access for ICS systems without requiring physical segmentation at each layer. The National Institute of Standards and Technology (NIST) proposed the[ zero trust architecture](https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-207.pdf) for industrial and enterprise networks, stating, “Perimeter-based network security has also been shown to be insufficient since once attackers breach the perimeter, further lateral movement is unhindered.” Applying the zero trust guiding principles of IT networks for workflow, system design, and operations can simplify and improve OT network security posture and help accelerate digital transformation. **[Read more.](/resources/security-terms-glossary/what-is-purdue-model-ics-security)** ### Title: What is the SolarWinds Cyberattack? | Zscaler ### Description: The SolarWinds cyberattack involved adversaries placing trojanized updates of Orion software on SolarWinds systems so they could attack SolarWinds customers. ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-the-solarwinds-cyberattack ### Question: What Is the SolarWinds Cyberattack? ### Answer: The SolarWinds cyberattack was a software [supply chain attack](/resources/security-terms-glossary/what-is-a-supply-chain-attack) involving the SolarWinds Orion platform, wherein a Russian nation-state adversary gained access to SolarWinds systems and deployed trojanized updates to the Orion software.

Many web security solutions reduce the security risk to your organization when your users accidentally access malicious files and websites. ### Question: Benefits of Web Security ### Answer: For a modern enterprise, effective web security has broad technical and human benefits: - ##### **Protect your business and stay compliant** by preventing loss of sensitive data - ##### **Protect customers and employees** by securing their private information - ##### **Avoid costly service interruptions** by preventing infections and exploits - ##### **Offer a better user experience** by helping your users stay safe and productive - ##### **Maintain customer loyalty and trust** by staying secure and out of the news ### Question: What does web security protect against? ### Answer: Web security casts a wide net to protect users and endpoints from malicious emails, encrypted threats, malicious or compromised websites and databases, malicious redirects, hijacking, and more. Let’s look at a few of the most common threats in more detail: - ##### **Ransomware:** These attacks encrypt data, and then demand a ransom payment in exchange for a decryption key. In a double-extortion attack, your data is also exfiltrated. - ##### **General malware:** Countless variants of malware exist that can lead to anything from data leaks, spying, and unauthorized access to lockouts, errors, and system crashes. - ##### **Phishing:** Often carried out through email, text messages, or malicious websites, these attacks trick users into things like divulging login credentials or downloading spyware. - ##### **SQL injection:** These attacks exploit an input vulnerability in a database server, allowing an attacker to execute commands that let them retrieve, manipulate, or delete data. - ##### **Denial of service (DoS):** These attacks slow or even shut down a network device such as a server by sending it more data than it can process. In distributed DoS—that is, a DDoS attack—this is carried out by many hijacked devices at once. - ##### **Cross-site scripting (XSS):** In this type of injection attack, an attacker introduces malicious code to a trusted website by entering it in an unprotected user input field. ### Question: How does web security work? ### Answer: Web security functions sit between your environment’s endpoints and the internet. From there, they inspect traffic and requests traveling in both directions. No single technology monitors or inspects all traffic, but a “stack” of appliances—or a cloud-delivered platform of services, more effective today—provides holistic coverage to prevent policy violations, malware infections, data loss, credential theft, and so on. Web Security includes the following technologies: - ##### **Secure web gateway (SWG)** - ##### **Firewall/IPS** - ##### **URL filtering** - ##### **Sandboxing** - ##### **Browser isolation** - ##### **DNS controls** - ##### **Antivirus** - ##### **TLS/SSL decryption** ### Title: What's Workload Protection?

Such a model puts aside the traditional "network perimeter"—inside of which all devices and users are trusted and given broad permissions—in favor of least-privilege access controls, granular microsegmentation, and multifactor authentication (MFA). [Read more](/resources/security-terms-glossary/what-is-zero-trust-architecture). ### Question: Difference between Zero Trust Architecture and Zero Trust Network Access? ### Answer: Before we examine [zero trust](/resources/security-terms-glossary/what-is-zero-trust) architecture in more detail, let's distinguish between these two interrelated terms: - **A zero trust architecture (ZTA)** is a design that supports zero trust principles, such as airtight access management, strict device and user authentication, and strong segmentation. It’s distinct from, and in many ways designed to replace, a “castle and moat” architecture, which trusts anything inside by default. - [**Zero trust network access (ZTNA)**](/resources/security-terms-glossary/what-is-zero-trust-network-access) is a zero trust use case that offers users secure access to applications and data when the users, apps, or data may not be inside a traditional security perimeter, which has become increasingly common in the age of the cloud and hybrid work. To put the two together, a zero trust architecture provides the foundation organizations need to deliver ZTNA and make their systems, services, APIs, data, and processes accessible from anywhere, at any time, and from any device. ## [Read more](/resources/security-terms-glossary/what-is-zero-trust-architecture). ### Question: How Zero Trust Architecture Works ### Answer: This is a three-step process: 1. **Verify identity and context.** Once the user/device, workload, or IoT/OT device requests a connection, irrespective of the underlying network, the zero trust architecture first terminates the connection and verifies identity and context by understanding the “who, what, and where” of the request. 2. **Control risk.** Once the identity and context of the requesting entity are verified and segmentation rules are applied, the zero trust architecture evaluates the risk associated with the connection request and inspects the traffic for cyberthreats and sensitive data. 3. **Enforce policy.** Finally, a risk score is computed for the user, workload, or device to determine whether it’s allowed or restricted. If the entity is allowed, the zero trust architecture establishes a secure connection to the internet, SaaS app, or IaaS/PaaS environment. [Read more](/resources/security-terms-glossary/what-is-zero-trust-architecture). ### Question: Benefits of Zero Trust Architecture ### Answer: A zero trust architecture provides the precise, contextual user access you need to run at the speed of modern business while protecting your users and data from malware and other cyberattacks. As the bedrock of ZTNA, an effective zero trust architecture helps you: - **Grant safe, fast access** to data and applications for remote workers, including employees and partners, wherever they are, improving the user experience - **Provide reliable remote access** as well as manage and enforce security policy more easily and consistently than you can with legacy technology like VPNs - **Protect sensitive data and apps**—on-premises or in a cloud environment, in transit or at rest—with tight security controls, including encryption, authentication, health checks, and more - **Stop insider threats** by no longer granting default, implicit trust to any user or device inside your network perimeter - **Restrict lateral movement** with granular access policies down to the resource level, reducing the likelihood of a breach - **Detect, respond to, and recover** from successful breaches more quickly and effectively to mitigate their impact - **Gain deeper visibility** into the what, when, how, and where of users’ and entities’ activities with detailed monitoring and logging of sessions and actions taken - **Assess your risk in real time** with detailed authentication logs, device and resource health checks, user and entity behavior analytics, and more.

Trust is never granted implicitly, and access is granted on a need-to-know, least-privileged basis defined by granular policies. ZTNA gives users secure connectivity to private apps without placing them on the network or exposing apps to the internet. ### Question: How Does ZTNA Work? ### Answer: ZTNA provides [secure remote access](/learn/secure-remote-access) to internal applications for any user, from anywhere, without putting critical resources at risk. To accomplish this, it starts with an architecture that's fundamentally different from a network-centric solution. Relying on a [software-defined perimeter (SDP)](/resources/security-terms-glossary/what-is-software-defined-perimeter), ZTNA enforces secure, identity-based access controls. This helps organizations replace their VPNs while reducing dependence on tools like DDoS protection, global load balancing, and firewalls. Following four core principles, ZTNA: 1. **Completely isolates app access from network access.** This reduces risks such as infection by compromised devices, granting only authorized users access to specific applications. 2. **Makes network and app infrastructure invisible to unauthorized users.** Outbound-only connections ensure IPs are never exposed to the internet, making the network impossible to find. 3. **Grants authorized users app access on a one-to-one basis.** Native app segmentation means users only have access to specific apps, not the full network, eliminating the risk of lateral movement. 4. **Takes a user-to-app approach, not a perimeter security approach.** The internet becomes the new corporate network, using end-to-end encrypted microtunnels instead of dedicated MPLS. ### Question: What’s the Difference Between VPN and ZTNA? ### Answer: | **Feature** | **VPN** | **ZTNA (Zero Trust Network Access)** | |---|---|---| | **Access Type** | Access to a network and its resources through an encrypted, private tunnel. | Secure least-privileged access to applications based on context verification. | | **Scalability** | Lacks scalability, making it difficult to apply security policies for remote workers and clouds. | Highly scalable with context-based controls, supporting distributed ecosystems. | | **Maintenance & Cost** | Time-consuming and expensive to deploy and maintain across distributed environments. | Easier to manage and more cost-efficient in secure, cloud-based environments. | | **Attack Surface** | Broad attack surface, enabling lateral movement for users with valid credentials. | Granular access controls restrict users to specific resources, preventing lateral movement. | | **User Experience** | Can hinder user experiences due to performance limitations and inefficiencies. | Direct user-to-application connections improve performance and optimize experience. | | **Authentication** | Relies solely on credentials for access validation. | Context-based authentication verifies multiple factors (device, location, identity) for added security. | ### Question: Operational Advantages of ZTNA ### Answer: With VPNs creating serious compliance and security risks, more and more organizations are discovering the advantages of ZTNA. Here are some of the top reasons to make the switch: - **No need for legacy appliances:** Completely replace legacy remote access appliances, such as VPNs, with a 100% software-based solution. - **Seamless user experiences:** Stop backhauling user traffic through the data center. Instead, grant users fast, direct access to applications. - **Effortless scale:** Scale with ease as needs change over time, only requiring provisioning of additional licenses, not new deployments. - **Fast deployment:** Deploy anywhere in just days, unlike appliance-based solutions that can take weeks or months to deploy. ### Question: Security Benefits of ZTNA ### Answer: ZTNA helps organizations strengthen their overall security posture and agility by delivering: - **Invisible infrastructure:** ZTNA gives authorized users access to applications, not the corporate network. This eliminates risk to the network while keeping infrastructure hidden. - **More control and visibility:** A centralized admin portal offers simpler management and granular controls, with real-time visibility into all user and app activity, and dynamic policy enforcement for users or groups. - **App segmentation made simple:** ZTNA enables granular segmentation at the application level, with no need to manage complex network-level segments. - **Integrated with SASE:** ZTNA is a key part of the [secure access service edge (SASE)](/resources/security-terms-glossary/what-is-sase) model, combining with tools like SD-WAN and [next-gen firewall (NGFW)](/resources/security-terms-glossary/what-is-next-generation-firewall) in a unified, cloud native platform. ### Question: How Does ZTNA Simplify Multicloud Access? ### Answer: ZTNA simplifies multicloud access by providing secure, direct connections between users and specific apps, wherever they are. It eliminates the need for complex network-level configurations or redundant VPNs, using identity-based authentication and granular access controls to unify security across clouds. ### Question: How to Implement ZTNA ### Answer: Implementing ZTNA follows a phased approach designed to ensure smooth adoption, enhance security, and reduce risks: - **Phase 1: Start with remote users.** Replace existing VPN solutions for remote access and map private app usage across your environment. Begin by defining access levels similar to current VPN settings to maintain productivity as users transition. - **Phase 2: Introduce microsegmentation.** Identify critical applications and create granular access policies for specific user groups. Prioritize segmenting infrastructure servers and management ports to protect high-value resources first. - **Phase 3: Expand ZTNA to all users.** Transition private app access for both remote and on-site users to ZTNA by configuring segments to route all resource access through encrypted microtunnels. Ensure context-based policies are applied universally. ### Question: Key Considerations for Choosing the Right ZTNA Solution ### Answer: In today's crowded marketplace, it's important to consider several other key criteria when evaluating ZTNA solutions against your unique needs: - **Client requirements:** Does the solution need an endpoint agent? What devices are supported? Agentless ZTNA is often critical for unmanaged device scenarios like BYOD and third-party access. - **Application support:** Can both web and legacy (data center) applications benefit from the same security features? - **Cloud residency:** Is the solution cloud-based? Does it meet security and residency needs? Cloud-delivered ZTNA often simplifies deployment and enhances DDoS resilience. - **Authentication standards:** What protocols are supported? Can it integrate with on-premises directories, cloud identity services, or existing identity providers? - **Edge locations:** How globally diverse are the vendor’s points of presence? - **Access control and posture:** Does the offering evaluate device health and security posture? Can it integrate with unified endpoint management (UEM)? Keep these things in mind as you look for [the vendor that complements your goals and vision](/blogs/company-news/ztna-technologies-what-they-are-why-now-and-how-choose). ### Question: Is ZTNA More Secure Than VPN? ### Answer: ZTNA is more secure than VPNs because it gives access only to specific apps instead of entire networks. This reduces risks like lateral movement, hiding sensitive systems from attackers, and shrinking the attack surface for better protection. ### Question: Which Industries Need ZTNA the Most? ### Answer: Industries like healthcare, finance, and tech may gain the most from ZTNA. However, for any organization that depends on remote teams, strict rules, or large networks, ZTNA helps them keep data and apps safe with least-privileged access. ### Question: How Hard Is ZTNA to Deploy and Manage? ### Answer: ZTNA is simple to set up and oversee. It works with cloud-based systems, so it deploys in days, not weeks. Its portals offer quick control of policies, instant user insights, and easy scaling for growth. ### Question: Can ZTNA Improve Cybersecurity in Hybrid Work Environments? ### Answer: ZTNA boosts security for hybrid work by limiting access to apps, stopping lateral movement, and changing policies based on device and location. It guards systems without slowing down or complicating user access. ### Question: Is ZTNA a Good Alternative to Legacy Network Segmentation? ### Answer: ZTNA is ideal for replacing network segmentation. It uses identity-based app permissions instead of complex network setups, removing over-access risks while simplifying security for workflows and cloud setups. ### Title: What Is Zero Trust? | Benefits & Core Principles - Zscaler ### Description: Zero trust is a security strategy - No person is trusted by default, Trust is based on what is happening & how safe the connection is. Reassessed for every new connection ### URL: https://www.zscaler.com/resources/security-terms-glossary/what-is-zero-trust ### Question: What Is Zero Trust? ### Answer: Zero trust is a security strategy that asserts that no entity—user, app, service, or device—should be trusted by default. Following the principle of least-privileged access, before any connection is allowed, trust is established based on the entity’s context and security posture, and then continually reassessed for every new connection, even if the entity was authenticated before. [Read more](/resources/security-terms-glossary/what-is-zero-trust). ### Question: How Does Zero Trust Security Work? ### Answer: As a core concept, zero trust assumes every component or connection is hostile by default, departing from earlier models based on secure network perimeters. This lack of trust is technologically defined by: - **The underlying** [**architecture**](https://cms.zscaler.com/resources/security-terms-glossary/what-is-zero-trust-architecture): Traditional models used approved IP addresses, ports, protocols for access controls and [remote access VPN](https://cms.zscaler.com/resources/security-terms-glossary/what-is-remote-access-vpn) for trust validation. - **An inline approach**: This considers all traffic as potentially hostile, even that within the network perimeter. Traffic is blocked until validated by specific attributes such as a fingerprint or identity. - **Context-aware policies**: This stronger security approach remains with the workload regardless of where it communicates—be it a public cloud, hybrid environment, container, or an on-premises network architecture. - **Multifactor authentication:** Validation is based on user, identity, device, and location. - **Environment-agnostic security**: Protection applies regardless of communication environment, promoting secure cross-network communications without need for architectural changes or policy updates. - **Business-oriented connectivity**: A zero trust model uses business policies for connecting users, devices, and applications securely across any network, facilitating [secure digital transformation](https://cms.zscaler.com/resources/security-terms-glossary/what-is-secure-digital-transformation). [Read more](/resources/security-terms-glossary/what-is-zero-trust). ### Question: Core Principles of the Zero Trust Model ### Answer: Zero trust is about more than user identity, segmentation, and secure access. It's a strategy upon which to build a cybersecurity ecosystem. At its core are three tenets: 1. ##### **Terminate every connection**: Technologies like firewalls use a “passthrough” approach, inspecting files as they are delivered. If a malicious file is detected, alerts are often too late. An effective zero trust solution terminates every connection to allow an inline proxy architecture to inspect all traffic, including encrypted traffic, in real time—before it reaches its destination—to prevent ransomware, malware, and more. 2. ##### **Protect data using granular context-based policies**: Zero trust policies verify access requests and rights based on context, including user identity, device, location, type of content, and the application being requested. Policies are adaptive, so user access privileges are continually reassessed as context changes. 3. ##### **Reduce risk by eliminating the attack surface:** With a zero trust approach, users connect directly to the apps and resources they need, never to networks (see ZTNA). Direct user-to-app and app-to-app connections eliminate the risk of lateral movement and prevent compromised devices from infecting other resources. Plus, users and apps are invisible to the internet, so they can’t be discovered or attacked. [Read more](/resources/security-terms-glossary/what-is-zero-trust). ### Question: What are the Benefits of Choosing a Zero Trust Architecture? ### Answer: 1. #### **Reduces business and organizational risk** 2. #### **Provides access control over cloud and container environments** 3. #### **Helps reduce the risk of a data breach** 4. #### **Supports compliance initiatives** #### [Read more](/resources/security-terms-glossary/what-is-zero-trust). ### Question: How to Get Started with Zero Trust? ### Answer: When designing a zero trust architecture, your security and IT teams should first focus on answering two questions: 1. What are you trying to protect? 2. From whom are you trying to protect it? This strategy will inform the way you design your architecture. Following that, the most effective approach is to layer technologies and processes on top of your strategy, not the other way around. In its [zero trust network access (ZTNA)](/resources/security-terms-glossary/what-is-zero-trust-network-access) framework, Gartner recommends leveraging zero trust delivered as a service. You can also take a phased approach, starting with either your most critical assets or a test case of non-critical assets, before implementing zero trust more broadly. Whatever your starting point, an optimal zero trust solution will offer you immediate returns in risk reduction and security control. [Read more](/resources/security-terms-glossary/what-is-zero-trust). ### Question: How Do I Set up Zero Trust Security? ### Answer: To set up zero trust security, identify critical assets and users, enforce strong authentication, implement least-privileged access, adopt user-to-app microsegmentation, continuously monitor activity, use endpoint protection, and validate every access request, ensuring no implicit trust. ### Question: Why Zero Trust? ### Answer: You should adopt zero trust because legacy security models, which assume anything inside the network is trustworthy by default, don't work in the age of cloud and mobility. Zero trust requires verification from all entities, whatever their device or location, before access is granted. A proactive approach such as this minimizes the potential impact of breaches by limiting lateral movement within the network, reducing the risk of insider threats, and enhancing overall security posture. ### Question: Zero Trust and SASE ### Answer: Zero trust and the [secure access service edge (SASE)](/resources/security-terms-glossary/what-is-sase) framework complement each other: zero trust maintains strict access controls and continuous verification, while SASE unifies network security and wide-area networking in a cloud-based service, delivering identity management, role-based access, threat prevention, and a consistent user experience. Effectively, zero trust provides the access framework while SASE offers the infrastructure and services to support it. ### Question: Zero Trust vs. VPN ### Answer: With a traditional VPN, users are authenticated once then placed on the network, granting them access to any and all resources. To make matters worse, VPNs require that user traffic be backhauled through a corporate data center, slowing down internet performance. Zero trust, on the other hand, connects users directly to private applications, improving both security and experience. ### Question: Why Is Zero Trust Security Important? ### Answer: Zero trust security is so important because it provides a solution to the shortcomings of traditional perimeter-based security in our hyperconnected digital world. Based on the premise that threats can come from anywhere—from outside a network as well as inside—zero trust enforces strict least-privileged access controls and continuous verification to help prevent breaches, reduce the blast radius of successful attacks, and hold up a strong security posture to face sophisticated, evolving threats. ### Question: What Are the Goals of Zero Trust? ### Answer: The goals of zero trust are to enhance security, protect sensitive data, and mitigate cyber risk. To accomplish this, zero trust architectures verify and validate every entity attempting access, implement strict access controls based on user identity and context, continuously monitor activity for potential security risks, and secure sensitive data to prevent unauthorized access. ### Question: Does Zero Trust Replace VPN? ### Answer: [Zero trust network access](/resources/security-terms-glossary/what-is-zero-trust-network-access) (ZTNA), an extension of the principle of [zero trust](/resources/security-terms-glossary/what-is-zero-trust), is the ideal [VPN](/zpedia/what-is-a-vpn) alternative. Today, private application access is shifting away from network-centric approaches to a user- and app-centric approach, leading to the increased popularity of zero trust and the adoption of ZTNA services. ZTNA enables secure access to private applications by establishing connectivity from user-to-application on a dynamic identity- and context-aware basis, providing reduced complexity, stronger security, and a smoother user experience compared to VPN. ### Question: How Does Combining Zero Trust Principles with AI Improve Cybersecurity? ### Answer: Combining zero trust with AI strengthens cybersecurity by continuously verifying users, devices, and behavior while detecting and responding to threats in real time. AI analyzes patterns to identify risks more quickly than manual methods, while zero trust enforces strict access controls, reducing the attack surface to limit potential damage # Products and Solutions Discover Zscaler’s solutions through detailed FAQs about securing your enterprise across users, devices, applications, and workloads.

Organizations should move away from this antiquated technology and adopt a zero-trust strategy. ### URL: https://www.zscaler.com/blogs/product-insights/remote-access-vpns-have-ransomware-their-hands ### Question: Footprint of a Malware Attack ### Answer: Let’s take a high-level look at the typical process for how malware is introduced to a network through a VPN vulnerability: 1. Cybercriminals scan the internet for unpatched remote access VPN servers. 2. Remote access to the network is achieved (without valid usernames or passwords). 3. Attackers view logs and cached passwords in plain text. 4. Domain admin access is gained. 5. Lateral movement takes place across the entire network. 6. Multifactor authentication (MFA) and endpoint security are disabled. 7. Ransomware (ex. Sodinokibi) is pushed to network systems. 8. The company is held up for ransom. [**Read more.**](/blogs/product-insights/remote-access-vpns-have-ransomware-their-hands) ### Question: VPN Disadvantages: ### Answer: Many organizations still feel that remote-access VPNs are necessary. And, in some cases, they may very well be. But, more often, VPNs are opening the network to the internet and, as a result, the business to increased risk. VPN Disadvantages are: - **Patching is often slow or forgotten** – Remembering, and even finding time to patch VPN servers, is plain difficult. Teams are asked to do more with less, often creating a human challenge that leads to security vulnerabilities. - **Placing users on the network** – Perhaps the genesis of all the issues related to remote-access VPNs. For VPNs to work, networks must be discoverable. This exposure opens the organization to attack. - **Lateral risk at exponential scale** – Once on the network, malware can spread laterally, despite efforts to perform network segmentation (which is a complex process in itself). As mentioned above, this can also lead to the takedown of other security technologies, such as MFA and endpoint security. - **The business’ reputation** – Your customers trust that you will protect their information and provide the best level of service to them. To do this, businesses must be able to protect themselves. News of a ransomware attack has a detrimental impact on your brand reputation.

It aims to provide secure and efficient access to applications and data, regardless of user location. **Zero Trust**, on the other hand, is a security model that operates on the principle of “never trust, always verify.” It requires continuous authentication and authorization of users and devices before granting access to resources, ensuring that no entity is trusted by default, even if it’s within the network perimeter. While Zero Trust focuses on strict access controls and verification, SASE encompasses a broader range of networking and security functions, often incorporating Zero Trust principles as a component of its architecture. ### Question: Does implementing SASE automatically provide Zero Trust? ### Answer: Not necessarily. While SASE solutions often include Zero Trust Network Access (ZTNA) as a component, achieving a comprehensive Zero Trust security posture requires more than just implementing SASE. Organizations must also establish robust identity and access management policies, continuous monitoring, and strict access controls to fully realize Zero Trust principles. ### Question: Which Is Better to Adopt First: Zero Trust or SASE? ### Answer: Zero trust is the ideal first step, as it focuses on securing users, devices, and access to critical resources.

Learn how zero trust eliminates risks, streamlines remote access, and scales with cloud environments. ### URL: https://www.zscaler.com/blogs/product-insights/replace-vpn-with-zero-trust-security ### Question: Why organizations are replacing VPNs with zero trust ### Answer: Organizations have traditionally relied on [virtual private network (VPN)](/zpedia/what-is-a-vpn) solutions to protect their networks and enable employees to work from anywhere. Over time, though, it became clear that these once-reliable gateways carry hidden complexities. Their overreliance on implicit trust and lack of visibility leaves environments more vulnerable than many leaders realize. In the following sections, we’ll explore the foundation of VPNs, discuss their growing challenges, and explain how [zero trust](/resources/security-terms-glossary/what-is-zero-trust) security is emerging as a stronger approach to securing resources while accommodating modern business needs. By the end, you’ll be well-prepared to assess whether it’s time to move beyond legacy VPN connections toward a more adaptive, cloud-native security model. ### Question: What are VPN solutions? ### Answer: VPNs establish an encrypted tunnel between a user’s device and a corporate network. By doing so, they shield sensitive data from prying eyes, making it seem as though the user is physically part of the organization’s internal environment. For a long time, installing VPN software on endpoints was the staple for remote workers needing to securely access critical databases or applications. ### Question: Increasing limitations and challenges of VPN solutions ### Answer: Although VPNs were once the gold standard for enterprise connectivity, they come with several pressing issues in complex environments. Below are the key hurdles organizations frequently encounter: - **Limited scalability:** As organizations grow, a single VPN server and its related configurations can become difficult to maintain. - **Complex administration:** VPN software needs frequent patches and troubleshooting on numerous endpoint devices. - **Security blind spots:** A trust model that assumes legitimacy can fail to screen certain network traffic for threats. - **High latency:** Routing data through a single hub or [data center](/zpedia/what-is-data-center) can slow performance, which frustrates teams. - **Inconsistent access control:** Granting uniform privileges to everyone makes it harder to meet the nuanced needs of various user groups. ### Question: Zero trust security: A modern VPN alternative ### Answer: Zero trust security revolutionizes how companies defend data, verifying every connection rather than automatically trusting a device or location. It advances beyond the belief that a single perimeter can protect the entire network, continuously checking each activity using context before granting permissions. As a result, more businesses are turning to this mindset as a robust successor to traditional VPNs, particularly in our era of remote operations and continuous cloud adoption. ### Question: What is zero trust security? ### Answer: Zero trust is a security model designed to eliminate implicit trust from every segment of the network. Built on the principle of “never trust, always verify,” it treats users and devices as inherently untrusted until they prove otherwise, which better defends against internal and external threats alike. While the principle behind zero trust is straightforward, it requires planning and strategy to put into practice. ### Question: Key benefits of zero trust security over VPN solutions ### Answer: Organizations adopting zero trust enjoy stronger protection and a smoother user experience. Below are five clear advantages over older VPN solutions: - **Stronger access control:** Fine-grained permissions ensure individuals only see what they need, reducing [lateral movement](/zpedia/what-is-lateral-movement). - **Enhanced visibility:** Constant monitoring goes beyond checking an IP address to detect suspicious behavior in real time. - **Reduced attack surface:** By making applications invisible to the open internet and never exposing the network, intruders struggle to find exploitable weak points. - **Better user experience:** Fewer steps are needed to securely open resources, improving productivity for distributed teams. - **Scalable cloud integrations:** A comprehensive trust architecture aligns seamlessly with decentralized environments to support future growth. ### Question: Overcoming challenges in shifting away from VPN solutions ### Answer: Moving from a familiar VPN setup to a zero trust approach can feel daunting, yet proper planning makes it more manageable. Consider the following best practices: 1. **Perform a complete asset inventory:** Before changing permissions or policies, map out which applications and data are most critical. 2. **Engage stakeholders early:** Make sure leadership, IT professionals, and end users understand the limitations of legacy VPN connections. 3. **Pilot new policies:** Implement zero trust security measures with a small group of remote workers or test environments to refine your strategy Before a full rollout. 4. **Adopt flexible tooling** Choose a platform that aligns with your existing workflows and operating systems so implementation runs smoothly. 5. **Train and communicate:** Provide open forums and resources so everyone can quickly adapt to the updated security stance. ### Question: How Zscaler zero trust is a fast, simple VPN alternative ### Answer: Zscaler empowers organizations to move [beyond the limits of legacy VPN](/products-and-solutions/vpn-alternative) by offering a [zero trust network access (ZTNA)](/products-and-solutions/zero-trust-exchange-zte) solution that delivers secure, seamless connectivity for today’s distributed workforce.

Unlike VPN solutions, which rely on perimeter-based security and provide broad access to network resources, zero trust strictly enforces access controls based on user identity, device status, and context. This minimizes the risk of unauthorized access and breaches. ### Question: Why Should I Replace My VPN with Zero Trust Security? ### Answer: VPNs are becoming outdated due to their vulnerability to modern threats such as phishing, credential theft, and lateral movement attacks. Zero trust provides more robust security by verifying every access request in real time and limiting interaction to only authorized resources. It’s more scalable, reliable, and better equipped to handle remote and hybrid work environments. ### Question: What Are the Most Common Vulnerabilities of VPN Solutions? ### Answer: VPNs often struggle to secure remote access against increasingly sophisticated cyberattacks. Common vulnerabilities include lack of granular access controls, difficulty enforcing multifactor authentication MFA, susceptibility to man-in-the-middle (MiTM) attacks, and performance issues as companies expand their networks. ### Question: Is Zero Trust Security Difficult to Implement Compared to a VPN? ### Answer: Implementing zero trust requires a shift in mindset and infrastructure, but many modern zero trust platforms are designed for seamless deployment. It involves steps such as identifying sensitive assets, mapping user permissions, and integrating identity-driven solutions. While initially more complex than setting up a VPN, zero trust ultimately offers simplicity and efficiency in security management. ### Question: Does Zero Trust Security Work for Both Remote and On-Premises Environments? ### Answer: Yes, zero trust is highly adaptable and offers consistent security across remote, hybrid, and on-premise environments. It ensures secure access for users and devices regardless of their location, making it ideal for organizations with diversified workforces. ### Question: How Does Zero Trust Impact Network Performance Compared to VPNs? ### Answer: VPNs often suffer from latency and bandwidth limitations, especially when supporting a large number of users. Zero trust security optimizes user access by connecting only to necessary resources, improving overall network efficiency and user experience. ### Question: What Role Does Identity Verification Play in Zero Trust Security? ### Answer: Identity verification is a cornerstone of zero trust security. It ensures that only authenticated users, devices, and applications can access resources within the network. By leveraging identity-based protocols such as MFA and behavioral monitoring, zero trust minimizes the risk of unauthorized access. ### Title: Building Resilient SaaS Security with Modern SSPM Tools ### Description: Learn how to strengthen your SaaS security architecture using modern SSPM tools to protect data, ensure compliance, and boost resilience against evolving threats. ### URL: https://www.zscaler.com/blogs/product-insights/build-resilient-saas-security-architecture-modern-sspm ### Question: What Is SaaS Security Posture Management (SSPM)? ### Answer: SSPM is a security discipline focused on continuously monitoring, assessing, and improving the security posture of SaaS applications by identifying misconfigurations, managing permissions, and automating remediation. ### Question: How Does SSPM Differ from CASB and CSPM? ### Answer: SSPM targets SaaS app configuration and user risk.
