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 that has read and write capabilities can only perform those functions at the same security level - nothing higher and nothing lower.






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






3. When a computer spends more time moving data from one small portion of memory to another THAN Actually processing the data






4. 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.






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






6. The Bell-LaPadula Model is a _______________.






7. 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

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






9. 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?






10. A form of ROM(Read-Only Memory) that can be modified after it has been manufactured. It can only be programmed only one time.






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






12. The Indexed memory addresses that software uses






13. Mandatory Protection






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






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






16. The Biba Model - _____________: A subject cannot read data from a lower Integrity level " No Read Down"






17. Execute one instruction at a time.






18. The reserved hard drive space used to Extend RAM capabilities. Windows system use the pagefile.sys file to reserve this space






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






20. Which Orange Book evaluation level is described as "Discretionary Security Protection"?






21. Applications and user activity






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






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






24. B1 is also called "Labeled Security" and each data object must have a classification label and each subject a clearance label. On each access attempt - the classification and clearance are checked to verify that the access is permissible.






25. B3 is also called "Security Domains" and imposes more granularity in each protection mechanism.






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






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






28. 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






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






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






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






32. Involves sharing the processor amoung all ready processes






33. TCSEC addresses Confidentiality - but _____________ . The TCSEC focuses mainly on one attribute of Security Confidentiality.






34. The Physical memory address that the CPU uses






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






36. Mandatory Access requires that _____________ be attached to all objects.






37. A is a form of EPROM - but its data storage can be erased and modified electrically by onboard programming circuitry and signals.






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






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






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






41. Which in the Orange Book ratings represents the highest level of trust?






42. Remaining parts of the operating system






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






44. 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.






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






46. 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 ___________.






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






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






49. To ensure that the Trusted Computing Base is not tampered with during shipment or installation.






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