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. Simpler instructions that require fewer clock cycles to execute.






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






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






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






5. System Architecture that separates system functionality into Hierarchical layers






6. Ensuring thta information does not flow from a higher security lever to a lower level in the Bell-LaPadula Model is referred to as ___________________ - which would take place through a "write down" operation. (An actual compromise occurs if and when






7. Contains the ending address






8. The TCB is the ________________ within a computer system that work together to enforce a security policy.






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. 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.






11. A nonvolatile storage media etc computer hard drive - floppy disks and CD-ROMs






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






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






14. Mandatory access control is enfored by the use of security labels.






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






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






17. 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.






18. In B2 Distinct address spaces must be provided to _________ - and a covert channel analysis is conducted. B2 adds assurance by adding requirements to the design of the system






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






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






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 Policy must be explicit and well defined and enforced by the mechanisms within the system






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






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






25. 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






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






27. Mandatory Protection






28. Verification Protection






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






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






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






32. 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.






33. Contains the beginning address






34. 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

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






38. Which increases the performance in a computer by overlapping the steps of different instructions?






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






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






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






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






43. The process of Evaluating the security stance of the software or system against a selected set of standards or policies. This may precede accreditation but is not a required precursor.

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






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






47. Discretionary protection






48. Discretionary access control is based on individuals and/or groups. It requires a separation of users and information and identification and authentication of individual entities
