CISSP Operational Security

  • 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. Mirrored set - creates an exact duplicate of all data to an additional disk. allows for data recovery in the event that n-1 disk fails

2. Administrative security control used in MAC systems where access determination is based upon a clearance level of subjects and classification levels of objects. Compartmentalization enforces need to know which necessitates that someone requires acces

3. Administrative control that makes sure employees have the proper rights and privileges to perform their work. escalation of priviliges can occur as employees are promoted or change jobs - yet their access rights and priveleges to systems and informat

4. Masquerading as another endpoint. presenting false information - usually within packets - to trick other systems and hide the origin of the message. done to prevent an identity from becoming uncovered

5. DOS - malformed packet - the teardrop attack is a malformed packet attack that targets issues with systems fragmentation reassembly. The attack involves sending packets with overlapping fragment offsets - which can cause a system attempting to reasse

6. More effective data sanitization technique where data on a drive is overwritten

7. A means to achieve data redundancy without incurring the same degree of cost as that of mirroring in terms of disk usage and write performance

8. Administrative control where employees are required to take a vacation. helps determine personnel single points of failure - detection and deterence of fraud - and the risk that comes with employees being unavailable for work. can also detect suspici

9. An online technique that involves attempting to authenticate a particular user to a system

10. Used to prevent an attack from being able to simply guess the correct password by attempting a large number of possibilities

11. DOS - resource exhaustion - most basic type of resource exhaustive attacks - and involve an attacker - or attacker controlled machines - initiating many connections to the victim - but not responding to the victim's SYN/ACK packets. The victim's conn

12. Mirrored striped set with distributed parity (some manufacturers label this as RAID 53)

13. Most often associated with providing an attacker with persistent backdoor access. Trojans provide desirable functionality that the user is seeking but also come with malicious functionality that the user does not anticipate

14. Any type of software that attacks a system or application - also called malicious code

15. Administrative control - a work related contractual agreement that ensures that employees - prior to being given sensitive information - will maintain the confidentiality and sensitivity of this information (also considered a directive control)

16. DOS - resource exhaustion - involves ICMP flooding. The attacker sends ICMP echo request messages with spoofed source addresses of the victim to the directed broadcast address of a network known to be smurf amplifier. As with most resource exhaustive

17. Define a minimum reporting threshold level and help differentiate an attack from noise - but can also cause false negatives

18. Redundant array of inexpensive disks - goal is to mitigate the risk of failure of a hard disk

19. Two parties conspire to undermine the security of the transaction

20. Distributed denial of service - many to one availability attack

21. Striped set - offers no data redundancy and is a poor choice if recovery of data is the reason for leveraging RAID

22. Uses the dictionary attack but makes alterations to the word before putting the guess through the hashing algorithm

23. An offline technique in which the attacker has gained access to the password hashes or database

24. Backup of any files that have changed since the last backup

25. Incident response stage in which a final report is presented to management. the goal is to detail ways in which the identification could have occurred sooner - the response could have been quicker or more effective - and organizational shortcomings t

26. Failover cluster - employs multiple systems that are already installed - configured - and plugged in - such that if a failover causes one of the systems to fail - then the other can be seamlessly leveraged to maintain the availability of the service

27. Striped set with distributed parity - uses block level striping - writes parity information that is used for recovery purposes. distributes the parity information across multiple disks. allows for data recovery in the event that one disk fails

28. A hot standy - configuration in which the backup systems only begin processing when a failure state is detected

29. The actors causing the threats that might exploit a vulnerability

30. Spreading data across multiple hard disks. increases performance and does create data redundancy

31. Confidentiality attack on network traffic - involves monitoring packets as they traverse a network.

32. Mirrored sets in a striped set (minimum four disks; even number of disks) provides fault tolerance and improved performance but increases complexity.

33. Striped set with dedicated parity at the byte level - data at the byte level is striped across multiple disks - but an additional disk is leveraged for storage of parity information - which is used for recovery in the event of a failure. allows for d

34. Deleting the file allocation on a storage device. important in security because it does not delete the data - it merely deletes the points that are used to find the data

35. Administrative security control that prescribes that multiple people are required to complete critical or sensitive transactions. The goal is to ensure that in order for someone to be able to abuse their access to sensitive information or transaction

36. Denial of service - one to one availability attack

37. Administrative control - the sensitivity of the position being filled largely determines the extent to which this control is used. Try to uncover any information that may indicate a prospective employee will be unable to perform their job

38. Incident response stage in which the affected system(s) are restored to operational status. typically the business unit responsible for the system will dictate when the system will go back online. close monitoring is necessary

39. An administrative security control that dictates a person should have no more access that the access that is strictly required to perform their job

40. Detection - containment - eradication - recovery - reporting

41. Writing the same data on multiple hard disks

42. Attacks against vulnerabilities with no patch or fix

43. Striped sets in a mirrored set (minimum four disks; even number of disks) provides fault tolerance and improved performance but increases complexity. The key difference from RAID 1+0 is that RAID 0+1 creates a second striped set to mirror a primary s

44. Trying all possible password combinations until a correct match between the hashes is found. may make use of rainbow tables which contain precomputed password-hash combinations

45. Incident response stage in which events are analyzed in order to determine whether these events might comprise a security incident. is the event occurring or has it occurred

46. Malicious code that hooks onto executable code - and requires user interaction to spread. In addition to spreading - the actual payload of the virus - that is - what it is intended to do - could be anything

47. Considered the most secure means of data sanititzation - commonly uses incineration or pulverization

48. Data that persists beyond noninvasive means to delete it. sometimes used to refer to residual data that remains after sanitization takes place

49. Means load balancing - each node in a HA cluster is actively processing data prior to failure

50. Stipulate all expectations regarding the providing of a service and its quality. what is considered acceptable regarding things such as bandwidth - time to delivery - response time - etc.
