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. Bell-LaPadula Model - ____________ : A subject at a given security level can NOT READ data that reside at a higher security level.

25. Mediates all access and Functions between subjects and objects.






26. Which evaluation class of the Trusted Network Interpretation (TNI) offers security domains?






27. A portion of a process. When the thread is generated - it shares the same domain(resources) as its process.






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






29. Used by Windows systems to reserve the "Swap Space"

33. Another word for Primary storage and distinguishes physical memory from virtual memory.






34. What access control technique is also known as multilevel security?






35. The process of Evaluating the security stance of the software or system against a selected set of standards or policies. This may precede accreditation but is not a required precursor.






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






37. Mandatory access control is enfored by the use of security labels.
