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






2. I/O drivers and utilities






3. 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






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






5. 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.






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






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






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






9. 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






10. The Bell-LaPadula Model is a _______________.






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






12. Discretionary protection






13. Which integrity model defines a constrained data item - an integrity verification procedure and a transformation procedure?






14. The Security Model Incorporates the ____________ that should be enforced in the system.






15. Security Policies that prevent information from flowing from a higher security level to a lower security level are called ____________.






16. 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.






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






18. The Bell-LaPaula Model's main goal was to ___________________ in an unauthorized manner. (Developed by the US gov)






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






20. Remaining parts of the operating system






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






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






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






24. Minimal Security






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






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






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






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






29. What Orange Book security rating is reserved for systems that have been evaluated but fail to meet the criteria and requirements of the higher divisions?






30. The Red Book aka Trusted Network Interpretation (TNI) - provides _________________ for Trusted computer and communications network systems under the areas of assurance requirements






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






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






33. 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.






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






35. A type of memory used for High-speed writing and reading activities.






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. The *-Property rule is refered to as ____________.






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






39. Involves sharing the processor amoung all ready processes






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






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






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






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






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






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






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






47. Verification Protection






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






49. Execute one instruction at a time.






50. The Biba Model adresses _____________________.
