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.

19. The Bell-LaPadula model Subjects and Objects are ___________.






20. 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

21. 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.






22. Happen because input data is not checked for appropriate length at time of input






23. Access control labels must be associated properly with objects.






24. The *-Property rule is refered to as ____________.






25. 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

39. The Physical memory address that the CPU uses






40. The total(sum)combination of protection mechanisms within a computer system. The TCB includes hardware - software - and firmware.






41. Software - hardware and firmware must be able to be tested individually to ensure that each enforces the security policy in an effective manner throughout their lifetimes.






42. The reference monitor is an access control concept - Referring to ________________ that mediates all accesses to objects by subjects based on information in an access control database.






43. Individual subjects must be uniquely identified.






44. Verification Protection






45. Requires more stringent authentication mechanisms and well-defined interfaces among layers.
