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. 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.

16. Which is a straightforward approach that provides access rights to subjects for objects?






17. When the address location that is specified in the program instruction contains the address of the final desired location.






18. A1 is also called "Verified Design" and requires formal verification of the design and specifications.

20. The type of environment that would require A1 systems is the most secure of secure environments. It deals with top-secret information and cannot adequately trust anyone using the systems without strict authentication - restrictions and auditing.






21. TCSEC provides a means to evaluate ______________________.






22. In the Orange Book - functionality and assurance are NOT _____________ as they are in the ITSEC and the Common Criteria.






23. Audit data must be captured and protected to enforce accountability






24. Bell-LaPadula Model -______________: A subject in a given security level can NOT WRITE information to a LOWER security level.






25. If an operating system permits executable objects to be used sequentially by multiple users without a refresh of the objects - what security problem is most likely to exist?

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






30. B1 is also called "Labeled Security" and each data object must have a classification label and each subject a clearance label. On each access attempt - the classification and clearance are checked to verify that the access is permissible.






31. What prevents a process from accessing another process' data?






32. Mandatory Access requires that _____________ be attached to all objects.






33. The object reuse concept must also be invoked - meaning that any medium holding data must not contain any remnants of information after it is released for another subject to use. All data must be efficiently erased once the subject is doen with the m
