CISSP Operational Security

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. A replica of all allocated data on a disk






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






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






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






5. 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.






6. 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






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






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






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






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






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






12. 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






13. 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






14. 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






15. 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






16. Denial of service - one to one availability attack






17. 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






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






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






20. 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)






21. 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






22. Striped set with dedicated parity at the block level - employs a dedicated parity drive rather than having parity data distributed amongst all disks. allows for data recovery in the event that one disk fails






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






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






25. 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






26. 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






27. 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.






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






29. 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






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






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






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






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






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






35. 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






36. Attacks against vulnerabilities with no patch or fix






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






38. Incident response stage in which the process of understanding the cause of the incident so that the system can be readily cleaned and ultimately restored.






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






40. 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






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






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






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






44. 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






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






46. 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






47. 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






48. 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






49. 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






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