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






2. 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?






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






4. Security Labels are not required until __________; thus C2 does not require security labels but B1 does






5. 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.






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






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






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






9. 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.






10. What prevents a process from accessing another process' data?

15. THE (Technische Hogeschool Eindhoven) - VAX/VMS - Multics and Unix . THE and Multics are no longer in use






16. What model use an access control triples and requires that the system maintain separation of duty ?






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






18. A portion of a process. When the thread is generated - it shares the same domain(resources) as its process.






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






20. System Architecture that separates system functionality into Hierarchical layers






21. Execute one instruction at a time.






22. Which TCSEC level first addresses object reuse?






23. The Simple Security rule is refered to as______________.






24. 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?






25. Minimal Security






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






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






28. A form of ROM(Read-Only Memory) that can be modified after it has been manufactured. It can only be programmed only one time.






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

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






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

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






37. When a computer uses more than one CPU in parallel to execute instructions is known as?






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






39. 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






40. 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.






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






42. Users are trusted but a certain level of accountability is required. C2 over is seen as the most reasonable class for commmercial applications - but the level of protection is still relatively weak.

44. 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.






45. A domain of trust that shares a single security policy and single management






46. In which users are processing information at the same sensitivity level; thus - strict access control and auditing measures are not required. It would be a trusted envirnment with low security concerns.
