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. What is called the formal acceptance of the adequacy of a system's overall security by management?






2. 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.






3. In the Bell-LaPadula Model the Subject's Label contains ___________________.






4. Using TPs (Transformation Procedures) to modify CDIs (Constrained Data) items is refered to as Well-Formed transaction






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






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






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






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






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






10. Applications and user activity






11. Which TCSEC level first addresses object reuse?






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






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






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






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






16. 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.






17. In the Orange Book - functionality and assurance are NOT _____________ as they are in the ITSEC and the Common Criteria.






18. This class ("Structured Protection") requires more stringent authentication mechanisms and well-defined interfaces between layers. Subjects and devices require labels and the system must not allow covert channels.






19. 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






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






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






22. Individual subjects must be uniquely identified.






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






24. The Biba Model adresses _____________________.






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






26. 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

27. When the RAM and secondary storage are combined the result is __________.






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






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






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






31. Which can be used as a covert channel?






32. Which is a straightforward approach that provides access rights to subjects for objects?






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






34. Discretionary protection






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






36. 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?






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






38. The Indexed memory addresses that software uses






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






40. For a subject to have read access to an object in a Multi-Level Security Policy - it is necessary that the subject's sensitivity label must ____________________.

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






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






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






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






45. The process of Evaluating the security stance of the software or system against a selected set of standards or policies. This may precede accreditation but is not a required precursor.






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






47. Which evaluation class of the Trusted Network Interpretation (TNI) offers security domains?






48. Succesfully Evaluated products are placed on?






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






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