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






2. Accreditation is also defined as an ____________________ by a designated authority that an information system is approved to operate in a particular security configuration with a prescribed set of safeguards






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






4. Contains the beginning address






5. 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?






6. 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.






7. Mandatory Protection






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






9. For rhe type of environment that processes sensitive data that require a higher degree of security. It requires systems that are relatively resistant to peneration and compromise






10. The Orange book does NOT Cover ________________ - And Database management systems






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






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






13. The Biba Model adresses _____________________.






14. The Biba Model is not concerned with security levels and confidentiality. It uses _________________.






15. The Availability - Integrity and confidentiality requirements of multitasking operating systems






16. 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.






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






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






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






20. Developed after the Bell-LaPadula model. Its a state machine model and is very similar to the Bell-LaPadula Model.






21. Involves sharing the processor amoung all ready processes






22. 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.






23. What are the components of an object's sensitivity label?






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






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






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






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






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






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






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






31. 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.






32. Applications and user activity






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






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






35. Which TCSEC level first addresses object reuse?






36. What does the Clark-Wilson security model focus on






37. TCSEC provides a means to evaluate ______________________.






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






39. 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






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






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






42. 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.






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






44. The Indexed memory addresses that software uses






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






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






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






48. Commonly referred to as The Big Mess Because of its lack of structure. MS-DOS is an example of a monolithic operation system






49. A subject at a given clearance may not read an object at a higher classification






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