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 "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






2. The Availability - Integrity and confidentiality requirements of multitasking operating systems






3. 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.






4. Which uses Protection Profiles and Security Targets?






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






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






7. B1 is the ___________________ of the Trusted Network Interpretation (TNI) or TCSEC that offers labeled security protection.






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






9. Levels of Security and Levels of Trust Lower Letters of the alphabet represent higher levels of security. Higher numbers indicate a greater level of trust.






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






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






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






13. The Biba Model - ______________: A subject cannot request service (invoke) to subjects of higher integrity






14. 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






15. The Indexed memory addresses that software uses






16. 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.






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






18. Succesfully Evaluated products are placed on?






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






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






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






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






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






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






25. Requires more stringent authentication mechanisms and well-defined interfaces among layers.






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






27. 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?






28. 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.






29. Reference Monitor is responsible for ______________ it compares the security labels of a subject and an object






30. The Bell-LaPadula Model is a _______________ that enforces Confidentiality aspect of access control. Formed by David Bell and Leonard LaPadula.






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






32. Ssoftware that is stored within ROM (Read-Only Memory) - (ROM is nonvolatile)






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






34. Which computer design approaches is based on the fact that in earlier technologies - the instruction fetch was the longest part of the cycle






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






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






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






38. Verification Protection






39. In ______________ the subject must have: Need to Know for ALL the information contained within the system.






40. TCSEC provides a means to evaluate ______________________.






41. Based on the Bell-LaPadula Security model - and evidence of reference monitor enforcement must be available.






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






43. 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.






44. Execute one instruction at a time.






45. What is defined as the hardware - firmware and software elements of a trusted computing base that implement the reference monitor concept?






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






47. Applications and user activity






48. An abstract machine which must mediate all access to subjects to objects - be protected from modification - be verifiable as correct - and is always invoked






49. Which can be used as a covert channel?






50. Discretionary protection
