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






2. 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






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






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






5. A replica of all allocated data on a disk






6. 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






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






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






9. 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






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






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






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






13. 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






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






15. 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.






16. 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






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






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






19. 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






20. 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






21. 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






22. Detection - containment - eradication - recovery - reporting






23. 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






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






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






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






27. Attacks against vulnerabilities with no patch or fix






28. 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






29. 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.






30. 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






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






32. 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)






33. 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






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






35. 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






36. 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






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






38. 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






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






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






41. Denial of service - one to one availability attack






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






43. 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






44. 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






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. 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






47. 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






48. 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






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






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