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 Biba Model adresses _____________________.






2. System Architecture that separates system functionality into Hierarchical layers






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






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






5. To ensure that the Trusted Computing Base is not tampered with during shipment or installation.






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






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






8. 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






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






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






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






12. TCSEC provides a means to evaluate ______________________.






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






14. If an operating system permits executable objects to be used sequentially by multiple users without a refresh of the objects - what security problem is most likely to exist?






15. Buffer overflows occurs when a program or process tries to store more data in a _____________ than it was intended to hold.






16. In access control terms - the word "dominate" refers to ___________.






17. 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.






18. Which evaluation class of the Trusted Network Interpretation (TNI) offers security domains?






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






20. 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.






21. Which is an ISO standard product evaluation criteria that supersedes several different criteria






22. 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.






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






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






25. 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.






26. I/O drivers and utilities






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






28. In both the Bell-LaPadula and Biba Models if the word "* or Star is used - _______________.






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






30. Which describe a condition when RAM and Secondary storage are used together?






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






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






33. 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.






34. Which is a straightforward approach that provides access rights to subjects for objects?






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






36. The Biba Model - ______________: A Subject cannot write data to an object at a higher integrity level (No write Up)






37. 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

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






41. Mediates all access and Functions between subjects and objects.






42. The Bell-LaPadula model Subjects and Objects are ___________.






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






44. Can be erased - modified and upgraded.

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






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






48. The first mathematical model of a multi-level security policy used to define the concept of a secure state - the modes of access - and rules for granting access?






49. Access control labels must be associated properly with objects.






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