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






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






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






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






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






6. 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.






7. Audit data must be captured and protected to enforce accountability






8. Discretionary protection






9. Succesfully Evaluated products are placed on?






10. 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.






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






12. 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.






13. The Bell-LaPadula Model is a _______________.






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






15. 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.






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






17. 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.






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






19. A is a form of EPROM - but its data storage can be erased and modified electrically by onboard programming circuitry and signals.






20. 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






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






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






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






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






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






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






27. Operating System Kernel






28. Software - hardware and firmware must be able to be tested individually to ensure that each enforces the security policy in an effective manner throughout their lifetimes.






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






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






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






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






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






34. Each data object must contain a classification label and each subject must have a clearance label.






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






36. Contains the beginning address






37. The _________________ specified in the Orange Book are: System architecture - System integrity - Covert channel analysis - Trusted facility management and Trusted recovery.






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






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






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






41. Execute one instruction at a time.






42. Verification Protection






43. 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.






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






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






46. 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.






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






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






49. TCSEC provides a means to evaluate ______________________.






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