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






2. In Access Control terms it means to be higher than or equal to. In the Bell-Lapadula Model - this is refered to as the dominance relation - which is the relationship of the subject's clearance to the object's classification

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






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






5. All users have a clearance for and a formal need to know about - all data processed with the system.






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






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






8. Documentation must be provided - including test - design - and specification document - user guides and manuals






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






10. TCSEC addresses Confidentiality - but _____________ . The TCSEC focuses mainly on one attribute of Security Confidentiality.






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






12. Individual subjects must be uniquely identified.






13. The total(sum)combination of protection mechanisms within a computer system. The TCB includes hardware - software - and firmware.






14. Discretionary protection






15. Which can be used as a covert channel?






16. 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






17. Accreditation is also defined as an ____________________ by a designated authority that an information system is approved to operate in a particular security configuration with a prescribed set of safeguards






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






19. When the contents of the address defined in the program's instruction is added to that of an index register.






20. What are the components of an object's sensitivity label?






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






22. The Biba Model is not concerned with security levels and confidentiality. It uses _________________.






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






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






25. The Orange book does NOT Cover ________________ - And Database management systems






26. The Biba Model adresses _____________________.






27. The Policy must be explicit and well defined and enforced by the mechanisms within the system






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






29. Mandatory Protection






30. The omission of networks and network components in the TCSEC was recognized and addressed in the "Trusted Network Interpretation of the TCSEC" otherwise known as ___________.






31. 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.






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






33. A channel within a computer system or network that is designed for the authorized transfer of information is identified as a(n)?






34. 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?






35. Developed after the Bell-LaPadula model. Its a state machine model and is very similar to the Bell-LaPadula Model.






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






37. 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.






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






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






40. Data in Cache can be accessed much more quickly than Data






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