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.

18. The reserved hard drive space used to Extend RAM capabilities. Windows system use the pagefile.sys file to reserve this space






19. In which users are processing information at the same sensitivity level; thus - strict access control and auditing measures are not required. It would be a trusted envirnment with low security concerns.






20. Contains an Address of where the instruction and dara reside that need to be processed.






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






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






23. 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.






24. Security is made up of: System administration - ________ - installation and configuration mechanisms within the environment - and other security issues.






25. What is called the formal acceptance of the adequacy of a system's overall security by management?






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






27. What does the simple security (ss) property mean in the Bell-LaPadula model?






28. Involves sharing the processor amoung all ready processes






29. Should always trace to individuals responsible for observing and recording the data






30. Verification Protection






31. The subject must have Need to Know for ONLY the information they are trying to access.






32. B1 is the ___________________ of the Trusted Network Interpretation (TNI) or TCSEC that offers labeled security protection.
