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






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






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






4. When a portion of primary memory is accessed by specifying the actual address of the memory location






5. 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






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






7. 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.






8. 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.






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






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

13. Accreditation is the authorization by management to _____________________. This authorization may be either provisional or full.






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






15. The Bell-LaPadula model Subjects and Objects are ___________.






16. 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

17. In B1 the security policy is based on Informal statement and the design specifications are reviewed and verified where as in B2 the ___________________ - and the system design and implementation are subject to more thorough review and testing procedu






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






19. Which integrity model defines a constrained data item - an integrity verification procedure and a transformation procedure?






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






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






22. A Policy based control. All objects and systems have a sensitivity level assigned to them






23. In ______________ the subject must have: Need to Know for ALL the information contained within the system.






24. Simpler instructions that require fewer clock cycles to execute.






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






26. Can be erased - modified and upgraded.






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






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






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






30. This type of environment is highly secured environment that processes very sensitive information. It requires systems that are highly resistant to penetration.






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






32. Documentation must be provided - including test - design - and specification document - user guides and manuals






33. The object reuse concept must also be invoked - meaning that any medium holding data must not contain any remnants of information after it is released for another subject to use. All data must be efficiently erased once the subject is doen with the m






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






35. The Physical memory address that the CPU uses






36. Verification Protection






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






38. When the address location that is specified in the program instruction contains the address of the final desired location.






39. An imaginary line that separates the trusted components of the TCB from those elements that are NOT trusted?






40. Has two individual assurace ratings. C1 and C2. The Higher the number of assurance rating the greater the protection






41. A1 is also called "Verified Design" and requires formal verification of the design and specifications.






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






43. Discretionary access control is based on individuals and/or groups. It requires a separation of users and information and identification and authentication of individual entities






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