Zero Trust Security Model Overview Answers 1. What is the primary benefit of network segmentation? A. Ease of access for all users B. Increased bandwidth across the network C. Isolation of sensitive data and applications D. Elimination of all potential threats Answer: Isolation of sensitive data and applications (C) Network segmentation is designed to isolate sensitive data and applications, preventing unauthorized access. 2. Which of the following best describes real-time threat detection and response? A. Drafting security policies only after incidents occur B. Monitoring network for anomalies and malicious activities C. Identifying threats during scheduled audits D. Conducting monthly vulnerability assessments Answer: Monitoring network for anomalies and malicious activities (B) Real-time threat detection and response involves monitoring the network actively for anomalies and malicious activities. 3. How does continuous monitoring enhance network security? A. By gathering all logs only during breaches B. By ensuring real-time awareness of anomalies C. By providing static security measures D. By periodically reviewing network configurations Answer: By ensuring real-time awareness of anomalies (B) Continuous monitoring ensures that there is real-time awareness of any anomalies or issues affecting network security. 4. What role does threat intelligence play in improving security measures? A. It provides insights for proactive threat identification. B. It only analyses internal traffics within the network. C. It replaces the need for security protocols. D. It solely focuses on historical security incidents. Answer: It provides insights for proactive threat identification. (A) Threat intelligence utilizes data and insights to proactively identify and respond to potential threats. 5. What is a key advantage of adopting micro-segmentation in a security strategy? A. Allowing unrestricted data access across the network B. Simplifying network architecture significantly C. Enhancing the speed of data transfer across all segments D. Diminishing the threat of lateral movement within the network Answer: Diminishing the threat of lateral movement within the network (D) Micro-segmentation helps in limiting the lateral movement of attacks, thereby minimizing potential damage. 6. What is a key principle of the Zero Trust security model regarding trust? A. Assumes no implicit trust B. Trust based on past behavior C. Trust based on network location D. Implied trust for internal users Answer: Assumes no implicit trust (A) The Zero Trust model emphasizes that no implicit trust should be assumed for any user or device, regardless of their location. 7. Which authentication method is part of identity verification in a Zero Trust model? A. Password protection only B. Physical key access C. Single-factor authentication D. Multi-Factor Authentication (MFA) Answer: Multi-Factor Authentication (MFA) (D) Multi-Factor Authentication (MFA) involves multiple methods of verification to ensure user identity across the network. 8. What is the primary benefit of micro-segmentation in a network? A. Increased network size B. Improvement of network speed C. Redundant data storage D. Isolation of resources during a breach Answer: Isolation of resources during a breach (D) Micro-segmentation allows for greater isolation of resources, limiting the impact of potential breaches in the network. 9. Which of the following is NOT a principle of Zero Trust? A. Continuous monitoring B. Least privilege access C. Verify everything D. Trust everything inside the perimeter Answer: Trust everything inside the perimeter (D) Trusting everything inside the network perimeter contradicts the Zero Trust principle, which rejects any implicit trust. 10. What does attribute-based access control (ABAC) rely on for authorizing access? A. User location only B. A single user identifier C. Access history logs D. A combination of user and environmental attributes Answer: A combination of user and environmental attributes (D) ABAC uses a combination of various attributes related to users, devices, and the environment for better access control. 11. How does continuous monitoring contribute to network security? A. By preventing unauthorized software installations B. By creating backups of important data C. By relying solely on periodic software updates D. By proactively identifying and responding to threats Answer: By proactively identifying and responding to threats (D) Continuous monitoring's primary role is to identify and respond to security threats in real time, enhancing overall security. 12. Which of the following best describes network segmentation? A. Limiting user access based on location B. Segregating network into smaller segments based on business functions C. Creating redundant pathways for data D. Dividing the network based on physical infrastructure only Answer: Segregating network into smaller segments based on business functions (B) Network segmentation refers to the practice of dividing the network into smaller segments, enhancing control and security. 13. What role do Intrusion Detection Systems (IDS) play in continuous monitoring? A. They automate user access approvals B. They manage user identities C. They identify and report suspicious activities D. They encrypt sensitive data transmissions Answer: They identify and report suspicious activities (C) Intrusion Detection Systems (IDS) are crucial for identifying and reporting any suspicious activities within the network.
