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. A replica of all allocated data on a disk






2. 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






3. Detection - containment - eradication - recovery - reporting






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






5. 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






6. 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






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






8. 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






9. 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






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






11. 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)






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






13. 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






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






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






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






17. 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






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






19. 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






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






21. 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






22. 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






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






24. Denial of service - one to one availability attack






25. 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






26. 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






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






28. 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






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






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






32. 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.






33. 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






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






35. 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.






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






37. 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






38. 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.






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






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






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






42. Writing the same data on multiple hard disks






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






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






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






47. 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






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






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






50. 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
