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






2. 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






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






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






5. 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






6. 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






7. 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






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






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






10. 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.






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






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






13. 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






14. Attacks against vulnerabilities with no patch or fix






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






16. 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






17. 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






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






19. Writing the same data on multiple hard disks






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






21. 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






22. Detection - containment - eradication - recovery - reporting






23. 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






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






25. 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.






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






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






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






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






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






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






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






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






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






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






36. 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






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






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






39. 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






40. 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






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






42. 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






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






44. 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






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






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






48. A replica of all allocated data on a disk






49. 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






50. 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
