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






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






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






4. A process that resides in a privileged domain to be able to execute its instructions and process its data with the assurance that programs in a different domain can NOT negatively affect its environment.






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






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






7. A1 is also called "Verified Design" and requires formal verification of the design and specifications.






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






9. 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.






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






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






12. 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.






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






14. Accreditation is also defined as an ____________________ by a designated authority that an information system is approved to operate in a particular security configuration with a prescribed set of safeguards






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






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






17. Used by Windows systems to reserve the "Swap Space"






18. 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

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






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






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






22. When a portion of primary memory is accessed by specifying the actual address of the memory location






23. The total(sum)combination of protection mechanisms within a computer system. The TCB includes hardware - software - and firmware.






24. The Simple Security rule is refered to as______________.






25. Which uses Protection Profiles and Security Targets?






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






27. An imaginary line that separates the trusted components of the TCB from those elements that are NOT trusted?






28. Configuration management is also defined in the Orange Book BUT As a _____________________ and NOT an operational assurance requirement.






29. TCSEC provides a means to evaluate ______________________.






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






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






32. 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






33. Mandatory Protection






34. 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






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






36. Remaining parts of the operating system






37. 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?






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






39. 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.






40. B3 is also called "Security Domains" and imposes more granularity in each protection mechanism.






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






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






43. 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.






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






45. Contains the ending address






46. Verification Protection






47. Discretionary protection






48. 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.






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






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