CISSP Security Architecture And Design

  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Based on the Bell-LaPadula Security model - and evidence of reference monitor enforcement must be available.

2. For a subject to have read access to an object in a Multi-Level Security Policy - it is necessary that the subject's sensitivity label must ____________________.

3. If a system initializes in a secure state and all allowed state transitions are secure - the every subsequent state will be secure no matter what inputs occur.

4. The group that oversees the processes of evaluation within TCSEC is?

10. A logical form of separation used by secure computing systems - Processes are _____________ so that each cannot access objects outside its permitted domain

11. What model use an access control triples and requires that the system maintain separation of duty ?

12. Which would be designated as objects on a MAC system?

16. Operating System Kernel

17. Discretionary protection

18. To ensure that the Trusted Computing Base is not tampered with during shipment or installation.

19. Configuration management is also defined in the Orange Book BUT As a _____________________ and NOT an operational assurance requirement.

20. Subjects and Objects cannot change their security levels once they have been instantiated (created)

21. The type of environment that would require A1 systems is the most secure of secure environments. It deals with top-secret information and cannot adequately trust anyone using the systems without strict authentication - restrictions and auditing.

22. In B1 the security policy is based on Informal statement and the design specifications are reviewed and verified where as in B2 the ___________________ - and the system design and implementation are subject to more thorough review and testing procedu

27. In access control terms - the word "dominate" refers to ___________.

28. A domain of trust that shares a single security policy and single management

29. Includes the security kernel as well as other security-related system functions that are within the boundary of the trusted computing base. System elements that are outside of the security perimeter need not be trusted.
