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






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






3. In B2 Distinct address spaces must be provided to _________ - and a covert channel analysis is conducted. B2 adds assurance by adding requirements to the design of the system






4. 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






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






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






7. The Physical memory address that the CPU uses






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






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






10. 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.






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






12. The security mechanisms and the system as a whole must perform predictably and acceptably in different situations continuously.






13. 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.






14. 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.






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






16. Levels of Security and Levels of Trust Lower Letters of the alphabet represent higher levels of security. Higher numbers indicate a greater level of trust.






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






18. Requires more stringent authentication mechanisms and well-defined interfaces among layers.






19. Remaining parts of the operating system






20. The type of environment that would require A1 systems is the most secure of secure environments. It deals with top-secret information and cannot adequately trust anyone using the systems without strict authentication - restrictions and auditing.






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






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






23. The C2 evaluation class of the _________________ offers controlled access protection.






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






25. Mandatory access control is enfored by the use of security labels.






26. When a computer spends more time moving data from one small portion of memory to another THAN Actually processing the data






27. A domain of trust that shares a single security policy and single management






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






29. What does the simple security (ss) property mean in the Bell-LaPadula model?






30. 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

31. Simpler instructions that require fewer clock cycles to execute.






32. A type of memory used for High-speed writing and reading activities.






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






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






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






36. 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 ____________________.

37. According to the Orange Book - trusted facility management is not required for which security levels?






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






39. Which addresses a portion of the primary memory by specifying the actual address of the memory location?






40. The reference monitor - in accordance with the security policy - ____________ that are made in the access control database.






41. Which Orange Book evaluation level is described as "Verified Design"?






42. What is defined as the hardware - firmware and software elements of a trusted computing base that implement the reference monitor concept?






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






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






45. 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.






46. The *-Property rule is refered to as ____________.






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






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






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