Test your basic knowledge |

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






2. 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






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






4. A replica of all allocated data on a disk






5. Detection - containment - eradication - recovery - reporting






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






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






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






9. 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






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






11. Writing the same data on multiple hard disks






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






13. 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






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






15. 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






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






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






18. 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






19. 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






20. 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






21. 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)






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






23. 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






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






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






26. 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






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






28. 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






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






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






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






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






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






35. 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






36. 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






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






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






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






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. 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






42. 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






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. 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 the process of understanding the cause of the incident so that the system can be readily cleaned and ultimately restored.






46. 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






47. 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.






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






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






50. 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.
