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. 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.






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






3. Bell-LaPadula model was proposed for enforcing access control in _____________________.






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






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






6. Bell-LaPadula Model - ____________ : A subject at a given security level can NOT READ data that reside at a higher security level.






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






8. The Bell-LaPadula Model is a _______________.






9. What Orange Book security rating is reserved for systems that have been evaluated but fail to meet the criteria and requirements of the higher divisions?






10. Documentation must be provided - including test - design - and specification document - user guides and manuals






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






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






13. 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.






14. 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.






15. Bell-LaPadula - ______________: This rule is based on named subjects and objects. It specifies that specific permissions allow a subject to pass on permissions to pass on permissions at its own discretion. These permissions are stored in an access ma






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






17. The total combination of protection mechanisms within a computer system






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






19. In B2 Subjects and devices requre labels and the system must NOT allow ________. No Trapdoors exists.






20. The Physical memory address that the CPU uses






21. 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.






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






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






24. In an automated system ________________ could be achieved by: A computer system designed to identify individuals responsible for any input.






25. 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.






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






27. 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.






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






29. 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.






30. As per FDA data should be ______________________________.






31. Users need to be Identified individually to provide more precise acces control and auditing functionality.






32. Discretionary protection






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






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






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






36. 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?






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






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






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






40. 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 ___________.






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






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






43. I/O drivers and utilities






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






45. Applications and user activity






46. For rhe type of environment that processes sensitive data that require a higher degree of security. It requires systems that are relatively resistant to peneration and compromise






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






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






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






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