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

2. A replica of all allocated data on a disk

3. Introducing a magnetic field to magnetic storage media. a degausser destroys the integrity of the magnetization of the storage media - making the data unrecoverable

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

5. Striped set with dual distributed parity - allows for recovery if two disks fail

6. Incident response stage in which the response team attempts to keep further damage from occurring as a result of the incident. also the phase where a binary forensic backup is made of systems involved in the incident.

7. Denial of service - one to one availability attack

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

9. 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

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

11. 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.

12. Back up any files that had changed since the last full backup

13. Writing the same data on multiple hard disks

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

15. 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

16. Term used for malware that is focused on hiding its own existence. Typical capabilities include file - folder - process - and network connection hiding. The techniques developed with rootkits are now commonly included in other types of malware

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

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

19. 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

20. 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

21. DOS - malformed packet - the land attack uses spoofed SYN packet that includes the victim's IP address and TCP port as both source and destination. This attack targets the TCPIP stack

22. Process: identify a change - propose a change - assess the risk associated with the change - test - schedule the change - notify impacted parties - implement - report the results to management - all changes must be tracked and auditable - a detailed

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

24. 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

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

26. 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

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

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

29. The medium that allows the threat agent to exploit a vulnerability

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

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

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

33. 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

34. 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

35. Malicious code that infects Microsoft Office documents by means of embedding malicious macros within them.

36. Dictionary attacks - directs the password cracking tool to use a supplied list of words as potential passwords.

37. DOS - Malformed packet - denial of service involved in sending a malformed ICMP echo request (ping) that was larger than the maximum size of an IP packet. Patching TCPIP stacks of systems removed the vulnerability of this DOS attack

38. 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

39. 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

40. Have the ability to self-propogate - or spread without user interaction. more well known worms: Code Red - Nimda - SQL Slammer - Blaster - MyDoom - Witty

41. 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

42. 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

43. Multi-raid - means that one standard RAID level is encapsulated within another.

44. DOS - resource exhaustion - a variation of the smurf attack - the main difference being that fraggle leverages UDP for the request portion - and stimulates an ICMP port unreachable message being sent to he victim rather than an ICMP echo response

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

46. 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

47. Places the attacker between the victim and another system. the attackers goal is to be able to serve as an undiscovered proxy for either or both of two endpoints engaging in communication. Uses sniffing and spoofing. The capabilities of session hijac

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

49. Detection - containment - eradication - recovery - reporting

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