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






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






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. Two parties conspire to undermine the security of the transaction






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






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






7. 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






8. 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






9. 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






10. 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






11. 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






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






13. Attacks against vulnerabilities with no patch or fix






14. 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






15. 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






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






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






18. 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






19. 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






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






21. 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.






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






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






24. Detection - containment - eradication - recovery - reporting






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






26. A replica of all allocated data on a disk






27. 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






28. 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






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






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






31. OS - like the smurf attack - leverages a third party - the attacker who has poorly configured third party DNS servers queries an attacker controlled DNS server and cahce the response (the maximum size DNS response). Once the large record is cached by






32. Denial of service - one to one availability attack






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






34. 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






35. 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






36. 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






37. 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






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






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. 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






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






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






43. 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






44. 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.






45. Administrative control where in order to mitigate risk and uncover potential fraud - employee's job or job functions are shifted and changed






46. 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






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






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






49. 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






50. 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
