3. Which NIST Special Publication provides the primary guidelines for computer security incident handling? → NIST SP 800-61
4. Which metric is most useful for evaluating program effectiveness in CISSP? → Outcome-based performance indicators
5. Which concept describes the risk that cloud data may be subject to the laws of the country where the data center resides? → Data sovereignty
6. What is the key benefit of evidence-based decision making in CISSP management? → It improves accuracy and reduces bias in decisions
7. What is the main purpose of a privacy impact assessment (PIA)? → To identify and mitigate privacy risks before deploying new systems or processes
8. In a SaaS model, who is responsible for patching the application software? → The cloud service provider
9. Which principle states that users should only have access necessary for their role? → Principle of least privilege
10. What role does collaboration play in business continuity for CISSP professionals? → It enhances outcomes through diverse perspectives and shared expertise
11. What is 'locard's exchange principle' and how does it apply to digital forensics? → Every contact leaves a trace — digital actions leave artifacts behind
12. What is the primary purpose of encryption in CISSP security? → To protect data confidentiality during storage and transmission
13. Which cloud service model gives customers the most control over the operating system and runtime environment? → IaaS
14. What cloud data security technique ensures that even if the provider is compromised, customer data remains unreadable? → Client-side encryption with customer-managed keys
15. What does a birthday attack imply? → An attack that attempts to find collisions in separate messages.
16. What is the recommended approach when managing conflicting priorities in CISSP? → Prioritize based on impact and urgency
17. Under the Computer Fraud and Abuse Act (CFAA), what element is typically required to establish unauthorized access? → Access to a protected computer without authorization or exceeding authorized access
18. Which skill is most critical for effective security and risk management? → Communication and stakeholder engagement
19. What is defense in depth in the context of CISSP security? → Implementing multiple layers of security controls
20. What is defense in depth in the context of CISSP security? → Implementing multiple layers of security controls
21. What is the primary purpose of a Cloud Access Security Broker (CASB)? → To enforce security policies between cloud service users and providers
22. Which type of malware analysis involves executing a suspicious file in a controlled environment to observe its behavior? → Dynamic analysis
23. In CISSP practice, what is the primary purpose of strategic planning? → To align resources with goals and anticipate challenges
24. In CISSP practice, reliability in assessment refers to: → The consistency and reproducibility of results
25. What is hypervisor type 1 (bare-metal) most commonly used for in cloud environments? → Running directly on hardware to host multiple guest VMs for cloud workloads
26. What is the purpose of a right-to-audit clause in a cloud service contract? → To grant the customer the ability to inspect provider security controls
27. What is the recommended response when a security incident is detected in an CISSP environment? → Follow the incident response plan: contain, eradicate, recover
28. A post-incident review is conducted after every major security incident. What is the primary goal of this activity? → To identify lessons learned and improve future response capabilities
29. Which forensic acquisition method produces a bit-for-bit copy of storage media, including deleted files and unallocated space? → Physical (raw) acquisition
30. What is the value of continuing education in cryptography for CISSP professionals? → It keeps professionals current with evolving standards and practices
