A national intelligence agency is designing a new system to process both Top Secret and Unclassified data simultaneously. Engineers propose using a formally verified microkernel operating system that enforces strict separation between processes through hardware-based memory isolation. During review, an executive asks why the team insists on this complex design instead of using simpler software-based access controls at the application layer. Which concept BEST justifies the microkernel approach? A. Complete mediation — ensuring every access request is validated against the security policy. B. Security kernel — implementing reference monitor functions at the lowest level of the system. C. Layered defense — using multiple, independent safeguards at different levels of abstraction. D. Economy of mechanism — minimizing system complexity to reduce potential vulnerabilities.

Which of the following organizations establishes the standards for Service Organization Control (SOC) audits? A: American Institute of Certified Public Accountants (AICPA) B: National Institute of Standards and Technology (NIST) C: International Organization for Standardization (ISO) D: International Electrotechnical Commission (IEC)

Which of the following threats would be MOST likely mitigated by monitoring assets containing open source libraries for vulnerabilities? A. Distributed denial-of-service (DDoS) attack B. Zero-day attack C. Phishing attempt D. Advanced persistent threat (APT) attempt

Hi all, Unfortunately, I didn’t pass the CISSP exam. I did tons of prep questions on learnzapp but seems that I’m not well prepared yet. Could you please recommend some info (tips) to follow that can help me ? Thank you

GlobalCorp, a multinational financial institution, is expanding its cloud presence, leveraging multiple Infrastructure as a Service (IaaS) providers. They are implementing a new data analytics platform that processes sensitive customer data from various regions. Due to recent regulatory changes in several countries, GlobalCorp must ensure strict data sovereignty and residency requirements. The Chief Information Security Officer (CISO) is concerned about the potential for data breaches and non-compliance with these regulations. The current security architecture lacks centralized visibility and control over data flows and access across the cloud providers. Which of the following is the MOST effective approach for GlobalCorp to address the challenges of data sovereignty, residency, and centralized security management in their multi-cloud environment? a) Implement a cloud-native security information and event management (SIEM) solution integrated with each IaaS provider's logging and monitoring services, focusing on regional data centers. b) Deploy a cloud access security broker (CASB) that provides visibility and control over data access, usage, and movement across all cloud providers, with data loss prevention (DLP) and encryption capabilities. c) Establish a dedicated security operations center (SOC) staffed with regional experts in each country where data is processed, relying on manual monitoring and incident response. d) Create a custom-built data governance platform that enforces data residency rules by replicating data across multiple regions within each cloud provider, ensuring redundancy and availability.
