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






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






3. According to the Orange Book - trusted facility management is not required for which security levels?






4. 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.






5. 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.






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






7. The Biba model (introduced in 1977) - The Sutherland model (published in 1986) - The Brewer-Nash model (published in 1989)






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






9. All users have a clearance for and a formal need to know about - all data processed with the system.






10. Access control labels must be associated properly with objects.






11. The combination of RAM - Cache and the Processor Registers






12. 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 ___________.






13. What access control technique is also known as multilevel security?






14. 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






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






16. 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






17. 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.






18. Logical access control mechanisms are used to enforce authentication and the uniquenes of each individual's identification.






19. Which can be used as a covert channel?






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






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






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






23. I/O drivers and utilities






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






25. 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.






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






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






28. 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.






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






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






31. Succesfully Evaluated products are placed on?






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






33. When a computer uses more than one CPU in parallel to execute instructions is known as?






34. When the contents of the address defined in the program's instruction is added to that of an index register.






35. The _________________ specified in the Orange Book are: System architecture - System integrity - Covert channel analysis - Trusted facility management and Trusted recovery.






36. The Security Model Incorporates the ____________ that should be enforced in the system.






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






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






39. The security kernel is the mechanism that _____________ of the reference monitor concept.






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






41. A channel within a computer system or network that is designed for the authorized transfer of information is identified as a(n)?






42. The centerpiece of the DoD Rainbow Series publications.Developed by the National Computer Security Center (NCSC)?






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






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






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






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






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