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






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






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






4. Which is an ISO standard product evaluation criteria that supersedes several different criteria






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






6. The TCB is the ________________ within a computer system that work together to enforce a security policy.






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






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






9. 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?






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






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






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






13. Applications and user activity






14. Contains an Address of where the instruction and dara reside that need to be processed.






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






16. In both the Bell-LaPadula and Biba Models if the word "Simple is used ______________.






17. The first mathematical model of a multi-level security policy used to define the concept of a secure state - the modes of access - and rules for granting access?






18. Can be erased - modified and upgraded.






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






20. Execute one instruction at a time.






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






22. What does the simple security (ss) property mean in the Bell-LaPadula model?






23. 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.






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






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






26. 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






27. TCSEC provides a means to evaluate ______________________.






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






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






30. In B2 Distinct address spaces must be provided to _________ - and a covert channel analysis is conducted. B2 adds assurance by adding requirements to the design of the system






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






32. Based on the Bell-LaPadula Security model - and evidence of reference monitor enforcement must be available.






33. Remaining parts of the operating system






34. 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.






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






36. 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.






37. Simpler instructions that require fewer clock cycles to execute.






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






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






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






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






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






43. Permits a database to have two records that are identical except for Their classifications






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






45. The subject must have Need to Know for ONLY the information they are trying to access.






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






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






48. In the Orange Book - functionality and assurance are NOT _____________ as they are in the ITSEC and the Common Criteria.






49. When the RAM and secondary storage are combined the result is __________.






50. The Indexed memory addresses that software uses
