CISSP Security Architecture And Design

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






2. Based on a known address with an offset value applied.






3. In Access Control terms it means to be higher than or equal to. In the Bell-Lapadula Model - this is refered to as the dominance relation - which is the relationship of the subject's clearance to the object's classification

18. The reference monitor - in accordance with the security policy - ____________ that are made in the access control database.






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






20. Bell-LaPadula Model - ______________: A subject that has read and write capabilities can only perform those functions at the same security level - nothing higher and nothing lower.






21. Developed after the Bell-LaPadula model. Its a state machine model and is very similar to the Bell-LaPadula Model.






22. System Architecture that separates system functionality into Hierarchical layers






23. The Biba model (introduced in 1977) - The Sutherland model (published in 1986) - The Brewer-Nash model (published in 1989)






24. When the address location that is specified in the program instruction contains the address of the final desired location.

26. The Bell-LaPadula Model is a _______________.






27. What does the Clark-Wilson security model focus on






28. Ensuring thta information does not flow from a higher security lever to a lower level in the Bell-LaPadula Model is referred to as ___________________ - which would take place through a "write down" operation. (An actual compromise occurs if and when






29. Which computer design approaches is based on the fact that in earlier technologies - the instruction fetch was the longest part of the cycle
