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. 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.






2. Which is an ISO standard product evaluation criteria that supersedes several different criteria

14. Based on the Bell-LaPadula Security model - and evidence of reference monitor enforcement must be available.






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






16. Reference Monitor is responsible for ______________ it compares the security labels of a subject and an object






17. The total combination of protection mechanisms within a computer system






18. 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






19. In both the Bell-LaPadula and Biba Models if the word "Simple is used ______________.






20. A ring protection system ________: User mode programs from direct access to peripherals and requires them to make use of services running at more privileged levels.






21. Has two individual assurace ratings. C1 and C2. The Higher the number of assurance rating the greater the protection






22. Which can be used as a covert channel?






23. In B1 the security policy is based on Informal statement and the design specifications are reviewed and verified where as in B2 the ___________________ - and the system design and implementation are subject to more thorough review and testing procedu






24. Bell-LaPadula Model - ______________: A subject that has read and write capabilities can only perform those functions at the same security level - nothing higher and nothing lower.






25. Permits a database to have two records that are identical except for Their classifications






26. A type of memory used for High-speed writing and reading activities.






27. Includes the security kernel as well as other security-related system functions that are within the boundary of the trusted computing base. System elements that are outside of the security perimeter need not be trusted.






28. Levels of Security and Levels of Trust Lower Letters of the alphabet represent higher levels of security. Higher numbers indicate a greater level of trust.






29. The Simple Security rule is refered to as______________.






30. 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.






31. There is only only one class in Division D. Reserved for systems that have been evaluated but fail to meet the criteria and requirements of the higher divisions.






32. In ______________ the subject must have: Need to Know for ALL the information contained within the system.






33. The Biba Model - _____________: A subject cannot read data from a lower Integrity level " No Read Down"






34. When the RAM and secondary storage are combined the result is __________.






35. The Biba Model - ______________: A Subject cannot write data to an object at a higher integrity level (No write Up)






36. Contains an Address of where the instruction and dara reside that need to be processed.






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

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






42. Simpler instructions that require fewer clock cycles to execute.






43. An imaginary line that separates the trusted components of the TCB from those elements that are NOT trusted?
