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. Attacks against vulnerabilities with no patch or fix






2. Backup of any files that have changed since the last backup






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






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






5. 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






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






7. 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






8. 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






9. 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






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






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






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






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






14. 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






15. 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






16. 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)






17. 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






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






19. 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






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






21. 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






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






23. 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






24. 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






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






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






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






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






29. 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.






30. 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






31. 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






32. 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






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






34. 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






35. 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






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






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






38. Writing the same data on multiple hard disks






39. 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






40. A replica of all allocated data on a disk






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






42. 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.






43. 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






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






45. 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






46. 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






47. 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






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






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






50. Denial of service - one to one availability attack
