Explanation
Answer: D - The U.S. Department of Defense developed the Trusted Computer System Evaluation Criteria (TCSEC) to evaluate operating systems, applications, and different other products have four criteria topics: security policy, accountability, assurance, and documentation. These four topics break down into seven different areas: 1) Security policy-the policy must be explicit and well defined and enforced by the mechanisms within the system. 2) Identification-individual subjects must be uniquely identified. 3) Labels-access control labels must be associated properly with objects. 4) Documentation-documentation must be provided, including test, design, and specification documents, user guides, and manuals. 5) Accountability-audit data must be captured and protected to enforce accountability. 6) Life-cycle assurance-software, hardware, and firmware must be able to be tested individually to ensure that each enforces the security policy in an effective manner through their lifetimes. 7) Continuous protection-the security mechanisms and the system as a whole must perform predictably and acceptably in different situations continuously.
