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. TCSEC provides a means to evaluate ______________________.

5. In both the Bell-LaPadula and Biba Models if the word "* or Star is used - _______________.






6. 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.






7. Components considered as part of the Trusted Computing Base (from the Orange Book) are?






8. In the Bell-LaPadula Model the Object's Label contains ___________________.

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






11. 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.

17. Trusted facility management is an assurance requirement only for ________________.






18. This type of environment is highly secured environment that processes very sensitive information. It requires systems that are highly resistant to penetration.






19. What does the simple security (ss) property mean in the Bell-LaPadula model?






20. The first mathematical model of a multi-level security policy used to define the concept of a secure state - the modes of access - and rules for granting access?






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






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






23. What is called the formal acceptance of the adequacy of a system's overall security by management?






24. Bell-LaPadula model was proposed for enforcing access control in _____________________.






25. Individual subjects must be uniquely identified.






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






27. Security is made up of: System administration - ________ - installation and configuration mechanisms within the environment - and other security issues.






28. The Indexed memory addresses that software uses






29. The Simple Security rule is refered to as______________.






30. Execute one instruction at a time.






31. What does the simple integrity axiom mean in the Biba model?






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

34. A logical form of separation used by secure computing systems - Processes are _____________ so that each cannot access objects outside its permitted domain






35. The hardware - firmware and software elements of a trusted computing base that implement the reference monitor concept.






36. Each data object must contain a classification label and each subject must have a clearance label.






37. Which addresses a portion of the primary memory by specifying the actual address of the memory location?






38. Mandatory Protection






39. Verification Protection






40. The biggest difference between System High Security Mode and Dedicated Security Mode is: ______.






41. Best defined as a mode of system termination that automatically leaves system processes and components in a secure state when a failure occurs or is detected in the system?






42. Which describe a condition when RAM and Secondary storage are used together?






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






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






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






46. 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?






47. The Orange Book describes four hierarchical levels to categorize security systems. Which levels require mandatory protection?






48. B3 is also called "Security Domains" and imposes more granularity in each protection mechanism.






49. 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.






50. Logical access control mechanisms are used to enforce authentication and the uniquenes of each individual's identification.
