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. In an automated system ________________ could be achieved by: A computer system designed to identify individuals responsible for any input.






2. In which users are processing information at the same sensitivity level; thus - strict access control and auditing measures are not required. It would be a trusted envirnment with low security concerns.






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






4. Trusted facility management is an assurance requirement only for ________________.






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






6. The Security Kernel is the Core of The TCB and is the _____________ to building trusted computing systems.






7. 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?






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






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






10. TCB contains The Security Kernel and all ______________.






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






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






13. A system uses the Reference Monitor to ___________________ of a subject and an object?






14. In access control terms - the word "dominate" refers to ___________.






15. 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.






16. TCSEC provides a means to evaluate ______________________.






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






18. Best defined as a mode of system termination that automatically leaves system processes and components in a secure state when a failure occurs or is detected in the system?






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






20. 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


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






22. Minimal Security






23. The Physical memory address that the CPU uses






24. When a vendor submits a product for evaluation - it submits it to the ____________.






25. 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.






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






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






28. The omission of networks and network components in the TCSEC was recognized and addressed in the "Trusted Network Interpretation of the TCSEC" otherwise known as ___________.






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






30. 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.






31. The assignment of a specific individual to administer the security-related functions of a system.






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






33. Happen because input data is not checked for appropriate length at time of input






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






35. Succesfully Evaluated products are placed on?






36. Should always trace to individuals responsible for observing and recording the data






37. 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.






38. Applications and user activity






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






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






41. The reference monitor - in accordance with the security policy - ____________ that are made in the access control database.






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






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






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






45. 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.






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






47. Security Labels are not required until __________; thus C2 does not require security labels but B1 does






48. I/O drivers and utilities






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






50. What does the simple security (ss) property mean in the Bell-LaPadula model?
