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. 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
