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. 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.






2. 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.






3. 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.






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






5. 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






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






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






8. TCSEC provides a means to evaluate ______________________.






9. The Biba model (introduced in 1977) - The Sutherland model (published in 1986) - The Brewer-Nash model (published in 1989)






10. 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?






11. In the Bell-LaPadula Model the Subject's Label contains ___________________.






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






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






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






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






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






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






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






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






20. The reference monitor is an access control concept - Referring to ________________ that mediates all accesses to objects by subjects based on information in an access control database.






21. If an operating system permits executable objects to be used sequentially by multiple users without a refresh of the objects - what security problem is most likely to exist?






22. 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?






23. A Policy based control. All objects and systems have a sensitivity level assigned to them






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






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






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






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






28. Each data object must contain a classification label and each subject must have a clearance label.






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






30. A process that resides in a privileged domain to be able to execute its instructions and process its data with the assurance that programs in a different domain can NOT negatively affect its environment.






31. Used by Windows systems to reserve the "Swap Space"






32. According to the Orange Book - trusted facility management is not required for which security levels?






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






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






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






36. Bell-LaPadula model was proposed for enforcing access control in _____________________.






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






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






39. The Bell-LaPadula Model is a _______________.






40. For a subject to have read access to an object in a Multi-Level Security Policy - it is necessary that the subject's sensitivity label must ____________________.

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






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






43. Accreditation is the authorization by management to _____________________. This authorization may be either provisional or full.






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






45. 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.






46. The Indexed memory addresses that software uses






47. 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






48. Execute one instruction at a time.






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






50. The Biba Model adresses _____________________.
