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.

25. Which in the Orange Book ratings represents the highest level of trust?






26. Each data object must contain a classification label and each subject must have a clearance label.






27. Users are trusted but a certain level of accountability is required. C2 over is seen as the most reasonable class for commmercial applications - but the level of protection is still relatively weak.
