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. 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






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. Denial of service - one to one availability attack






4. 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






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






6. 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






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






8. 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






9. 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






10. 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






11. 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.






12. 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






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






14. 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






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






16. 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






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






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






19. 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.






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






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






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






23. 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






24. 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)






25. 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.






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






27. 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






28. 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






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






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






31. 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






32. 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






33. Attacks against vulnerabilities with no patch or fix






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






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






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






38. 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






39. 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






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






41. 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






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






43. 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






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






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






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






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






48. A replica of all allocated data on a disk






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






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