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

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






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






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






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






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






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






22. Which TCSEC level first addresses object reuse?






23. Can be erased - modified and upgraded.






24. 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.






25. Ensuring thta information does not flow from a higher security lever to a lower level in the Bell-LaPadula Model is referred to as ___________________ - which would take place through a "write down" operation. (An actual compromise occurs if and when






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






27. An organization within the National Security Agency (NSA) is responsible for Evaluating computer systems and products. The Trusted Product Evaluation program (TPEP) oversees the testing by approved entities of commercial products against a specific s






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






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






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






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






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






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






34. THE (Technische Hogeschool Eindhoven) - VAX/VMS - Multics and Unix . THE and Multics are no longer in use






35. Levels of Security and Levels of Trust Lower Letters of the alphabet represent higher levels of security. Higher numbers indicate a greater level of trust.






36. Bell-LaPadula - ______________: This rule is based on named subjects and objects. It specifies that specific permissions allow a subject to pass on permissions to pass on permissions at its own discretion. These permissions are stored in an access ma






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






38. Execute one instruction at a time.






39. Which addresses a portion of the primary memory by specifying the actual address of the memory location?






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. Mediates all access and Functions between subjects and objects.






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






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






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