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






2. 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






3. Detection - containment - eradication - recovery - reporting






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






5. 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






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






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






8. 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






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






10. 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






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






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






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






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






15. 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






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






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






18. Attacks against vulnerabilities with no patch or fix






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






20. 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






21. 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






22. 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.






23. 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






24. 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.






25. Denial of service - one to one availability attack






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






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






28. 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






29. 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)






30. A replica of all allocated data on a disk






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






32. 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






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






34. 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






35. 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






36. 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






37. 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






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






39. 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






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






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






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






43. 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






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






46. 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






47. 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.






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






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






50. 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
