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. The Orange book requires protection against two_____________ - which are these Timing and Storage






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






3. Contains the beginning address






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






5. 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

6. The security mechanisms and the system as a whole must perform predictably and acceptably in different situations continuously.






7. Which Orange Book evaluation level is described as "Controlled Access Protection"? - This class requires a more granular method of providing access control. The system must enforce strict logon procedures and provide decision-making capabilites when






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






9. The security kernel is the mechanism that _____________ of the reference monitor concept.






10. 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.






11. The Indexed memory addresses that software uses






12. As per FDA data should be ______________________________.






13. 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






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






15. Commonly referred to as The Big Mess Because of its lack of structure. MS-DOS is an example of a monolithic operation system






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






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






18. Can be erased - modified and upgraded.






19. Intended for environments that require systems to handle classified data.






20. The reference monitor - in accordance with the security policy - ____________ that are made in the access control database.






21. Individual subjects must be uniquely identified.






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






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






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






25. Based on The Bell-LaPadula model - because it allows for multilevel security to be integrated into the code.






26. 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.






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






28. The group that oversees the processes of evaluation within TCSEC is?






29. The Biba Model adresses _____________________.






30. According to the Orange Book - which security level is the first to require a system to protect against covert timing channels?






31. A set of objects that a subject is able to access






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






33. Using TPs (Transformation Procedures) to modify CDIs (Constrained Data) items is refered to as Well-Formed transaction






34. The Reserved hard drive space used to to extend RAM capabilites.






35. For rhe type of environment that processes sensitive data that require a higher degree of security. It requires systems that are relatively resistant to peneration and compromise






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






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






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






39. 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.






40. In B2 Subjects and devices requre labels and the system must NOT allow ________. No Trapdoors exists.






41. Applications and user activity






42. When a portion of primary memory is accessed by specifying the actual address of the memory location






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






44. In an automated system ________________ could be achieved by: A computer system designed to identify individuals responsible for any input.






45. n this class more granularity is provided in each protection mechanism - and the programming code that is not necessary to support the security policy is excluded.






46. Based on a known address with an offset value applied.






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






48. Which Orange Book evaluation level is described as "Discretionary Security Protection"?






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






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