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






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






3. 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






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






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






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






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






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






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






10. 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.






11. 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






12. Denial of service - one to one availability attack






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






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






15. 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






16. 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






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






18. 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






19. A replica of all allocated data on a disk






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






21. 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






22. 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






23. 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






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






25. 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






26. Detection - containment - eradication - recovery - reporting






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






28. 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






29. 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






30. 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






31. 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






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






33. 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






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






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






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






37. 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






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. 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






40. 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






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






42. 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.






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






45. 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






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






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






48. 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






49. 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.






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