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. Which uses Protection Profiles and Security Targets?






2. A nonvolatile storage media etc computer hard drive - floppy disks and CD-ROMs






3. A portion of a process. When the thread is generated - it shares the same domain(resources) as its process.






4. Which Orange Book evaluation level is described as "Discretionary Security Protection"?

11. 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






12. 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.






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

18. A channel within a computer system or network that is designed for the authorized transfer of information is identified as a(n)?






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






20. Includes the security kernel as well as other security-related system functions that are within the boundary of the trusted computing base. System elements that are outside of the security perimeter need not be trusted.






21. Which can be used as a covert channel?






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






23. The centerpiece of the DoD Rainbow Series publications.Developed by the National Computer Security Center (NCSC)?






24. 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.






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






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






27. All users have a clearance for and a formal need to know about - all data processed with the system.






28. THE (Technische Hogeschool Eindhoven) - VAX/VMS - Multics and Unix . THE and Multics are no longer in use






29. A ring protection system ________: User mode programs from direct access to peripherals and requires them to make use of services running at more privileged levels.






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






31. Bell-LaPadula Model -______________: A subject in a given security level can NOT WRITE information to a LOWER security level.






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






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






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






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






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






37. 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






38. 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?






39. 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

41. The Simple Security rule is refered to as______________.






42. Developed after the Bell-LaPadula model. Its a state machine model and is very similar to the Bell-LaPadula Model.






43. TCSEC provides a means to evaluate ______________________.






44. 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.






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






46. Based on the Bell-LaPadula Security model - and evidence of reference monitor enforcement must be available.






47. 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
