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. 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

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






4. To ensure that the Trusted Computing Base is not tampered with during shipment or installation.






5. What does the * (star) property mean in the Bell-LaPadula model?






6. The C2 evaluation class of the _________________ offers controlled access protection.






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






8. Configuration management is also defined in the Orange Book BUT As a _____________________ and NOT an operational assurance requirement.






9. 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?






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






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






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






13. In access control terms - the word "dominate" refers to ___________.






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






15. Subjects and Objects cannot change their security levels once they have been instantiated (created)






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






17. Verification Protection






18. Which TCSEC level first addresses object reuse?






19. Accreditation is the authorization by management to _____________________. This authorization may be either provisional or full.






20. Can be erased - modified and upgraded.






21. Succesfully Evaluated products are placed on?






22. 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






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






24. This class ("Structured Protection") requires more stringent authentication mechanisms and well-defined interfaces between layers. Subjects and devices require labels and the system must not allow covert channels.






25. Discretionary access control is based on individuals and/or groups. It requires a separation of users and information and identification and authentication of individual entities






26. The Bell-LaPadula Model is a _______________.






27. Which Orange Book evaluation level is described as "Verified Design"?






28. Users need to be Identified individually to provide more precise acces control and auditing functionality.






29. What does the Clark-Wilson security model focus on

35. A subject at a given clearance may not read an object at a higher classification






36. 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.






37. 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.
