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. 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






2. A replica of all allocated data on a disk






3. 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






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






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






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






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






9. 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.






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






11. Attacks against vulnerabilities with no patch or fix






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






13. 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






14. 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






15. 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






16. 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.






17. 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






18. 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






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






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






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






22. Denial of service - one to one availability attack






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






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






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






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






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






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






29. 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






30. 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






31. 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






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






33. 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






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. 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






36. 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






37. 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






38. Detection - containment - eradication - recovery - reporting






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






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. 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






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






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






45. 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






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






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






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






49. 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






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