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






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






3. What is called the formal acceptance of the adequacy of a system's overall security by management?






4. Minimal Security






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






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






7. 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.






8. 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.






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






10. 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.






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






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






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






14. 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?






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






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






17. Remaining parts of the operating system






18. The Biba Model is not concerned with security levels and confidentiality. It uses _________________.






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






20. Commonly referred to as The Big Mess Because of its lack of structure. MS-DOS is an example of a monolithic operation system






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






22. 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.






23. 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






24. The security mechanisms and the system as a whole must perform predictably and acceptably in different situations continuously.






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






26. 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 ___________.






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






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






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






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






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






32. 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






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






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






35. 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?






36. The Red Book aka Trusted Network Interpretation (TNI) - provides _________________ for Trusted computer and communications network systems under the areas of assurance requirements






37. Can be erased - modified and upgraded.






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






39. A logical form of separation used by secure computing systems - Processes are _____________ so that each cannot access objects outside its permitted domain






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






41. I/O drivers and utilities






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






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






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






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






46. The Simple Security rule is refered to as______________.






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






48. Ensuring thta information does not flow from a higher security lever to a lower level in the Bell-LaPadula Model is referred to as ___________________ - which would take place through a "write down" operation. (An actual compromise occurs if and when
