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.

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






17. 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.






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






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






20. The Biba Model adresses _____________________.






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






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






23. 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






24. The Biba Model is not concerned with security levels and confidentiality. It uses _________________.






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






26. Based on a known address with an offset value applied.






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






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

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






31. 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






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






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






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






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