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 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

11. 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


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






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






14. 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.

18. The Orange book does NOT Cover ________________ - And Database management systems






19. 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.






20. TCB contains The Security Kernel and all ______________.






21. Happen because input data is not checked for appropriate length at time of input






22. Mandatory Protection






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






24. Individual subjects must be uniquely identified.






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






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






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






28. 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 ____________________.


29. System Architecture that separates system functionality into Hierarchical layers






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






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






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






33. Certification is a Technical review that assesses the _____________ - where as Accreditation is management's Official acceptance of the information in the Certification process findings.






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






35. 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






36. 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.






37. Security is made up of: System administration - ________ - installation and configuration mechanisms within the environment - and other security issues.






38. 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.
