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






2. 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.






3. The hardware - firmware and software elements of a trusted computing base that implement the reference monitor concept.






4. The group that oversees the processes of evaluation within TCSEC is?






5. 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.






6. 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 ____________________.

7. 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






8. Should always trace to individuals responsible for observing and recording the data






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






10. The Security Model Incorporates the ____________ that should be enforced in the system.






11. Contains the beginning address






12. Ssoftware that is stored within ROM (Read-Only Memory) - (ROM is nonvolatile)






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






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






15. The omission of networks and network components in the TCSEC was recognized and addressed in the "Trusted Network Interpretation of the TCSEC" otherwise known as ___________.






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






17. Accreditation is the authorization by management to _____________________. This authorization may be either provisional or full.






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






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






20. What access control technique is also known as multilevel security?






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






22. Users are trusted but a certain level of accountability is required. C2 over is seen as the most reasonable class for commmercial applications - but the level of protection is still relatively weak.






23. What does the * (star) property mean in the Bell-LaPadula model?






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






25. The reference monitor is an access control concept - Referring to ________________ that mediates all accesses to objects by subjects based on information in an access control database.






26. The Orange Book describes four hierarchical levels to categorize security systems. Which levels require mandatory protection?






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






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






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






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






31. 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.






32. The reserved hard drive space used to Extend RAM capabilities. Windows system use the pagefile.sys file to reserve this space






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






34. A subject at a given clearance may not read an object at a higher classification






35. Which would be designated as objects on a MAC system?






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






37. Intended for environments that require systems to handle classified data.






38. The Security Kernel is the Core of The TCB and is the _____________ to building trusted computing systems.






39. The process of Evaluating the security stance of the software or system against a selected set of standards or policies. This may precede accreditation but is not a required precursor.






40. The Biba Model - _____________: A subject cannot read data from a lower Integrity level " No Read Down"






41. Contains the ending address






42. The security kernel is the mechanism that _____________ of the reference monitor concept.






43. Using TPs (Transformation Procedures) to modify CDIs (Constrained Data) items is refered to as Well-Formed transaction






44. Mandatory Protection






45. The Biba model (introduced in 1977) - The Sutherland model (published in 1986) - The Brewer-Nash model (published in 1989)






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






47. What does the simple integrity axiom mean in the Biba model?






48. 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?






49. 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.






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