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. Writing the same data on multiple hard disks






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






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






4. Attacks against vulnerabilities with no patch or fix






5. 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.






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






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






8. 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






9. 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






10. 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






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






12. 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






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






14. 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






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






16. 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






17. 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






18. 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






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






20. 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






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






22. 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






23. 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






24. 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






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






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






28. 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






29. 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






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






31. Denial of service - one to one availability attack






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






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






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






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






37. 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






38. 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






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






40. 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)






41. 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






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






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






44. 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






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






46. 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.






47. 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






48. 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






49. 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






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