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






2. 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






3. 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.






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






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






6. 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)






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






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






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






10. Detection - containment - eradication - recovery - reporting






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






12. Writing the same data on multiple hard disks






13. 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






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






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






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






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. 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






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






20. 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.






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






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






23. 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






24. 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






25. 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.






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






27. 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






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






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






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






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






32. 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






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






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






35. 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






36. A replica of all allocated data on a disk






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






38. 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






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






40. 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






41. Denial of service - one to one availability attack






42. 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






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






44. 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






45. 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






46. 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






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






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






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






50. 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
