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






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






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






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






5. Which would be designated as objects on a MAC system?






6. Components considered as part of the Trusted Computing Base (from the Orange Book) are?






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






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






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






10. 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.






11. 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.






12. 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.






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






14. 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.






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






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






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






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






19. 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?






20. Execute one instruction at a time.






21. The subject must have Need to Know for ONLY the information they are trying to access.






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






23. In B2 Subjects and devices requre labels and the system must NOT allow ________. No Trapdoors exists.






24. 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.






25. The reference monitor must mediate all access - _____________ - be verifiable as correct - and must always be invoked.






26. There is only only one class in Division D. Reserved for systems that have been evaluated but fail to meet the criteria and requirements of the higher divisions.






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






28. A logical form of separation used by secure computing systems - Processes are _____________ so that each cannot access objects outside its permitted domain






29. This type of environment is highly secured environment that processes very sensitive information. It requires systems that are highly resistant to penetration.






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






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






32. Security is made up of: System administration - ________ - installation and configuration mechanisms within the environment - and other security issues.






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






34. When the address location that is specified in the program instruction contains the address of the final desired location.






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






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






37. The Simple Security rule is refered to as______________.






38. In both the Bell-LaPadula and Biba Models if the word "Simple is used ______________.






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






40. The Bell-LaPadula model Subjects and Objects are ___________.






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






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






43. 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. The Biba Model adresses _____________________.






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






46. 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






47. Remaining parts of the operating system






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






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






50. Bell-LaPadula Model - ______________: A subject that has read and write capabilities can only perform those functions at the same security level - nothing higher and nothing lower.
