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






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






3. 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






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






5. 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.






6. 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 ___________.






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






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






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






10. When a vendor submits a product for evaluation - it submits it to the ____________.






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






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






13. Verification Protection






14. Configuration management is also defined in the Orange Book BUT As a _____________________ and NOT an operational assurance requirement.






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






16. In an automated system ________________ could be achieved by: A computer system designed to identify individuals responsible for any input.






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






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






19. 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






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






21. 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






22. n this class more granularity is provided in each protection mechanism - and the programming code that is not necessary to support the security policy is excluded.






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






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






25. Contains an Address of where the instruction and dara reside that need to be processed.






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






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






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






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






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






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






32. According to the Orange Book - which security level is the first to require a system to protect against covert timing channels?






33. 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

34. Which computer design approaches is based on the fact that in earlier technologies - the instruction fetch was the longest part of the cycle






35. 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.






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






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






38. 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?






39. The subject must have Need to Know for ONLY the information they are trying to access.






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






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






42. 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.






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






44. 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?






45. 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.






46. In the Bell-LaPadula Model the Object's Label contains ___________________.






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






48. 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
