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






2. 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






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






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






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






6. Writing the same data on multiple hard disks






7. 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






8. 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






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






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






11. 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






12. 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






13. 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.






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






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






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






17. 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






18. 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.






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






20. 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






21. A replica of all allocated data on a disk






22. 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






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






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






26. 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






27. 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






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






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






30. 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






31. 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






32. 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






33. 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






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






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. 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)






37. 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.






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. 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






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






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






42. 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






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






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






45. 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






46. 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






47. Denial of service - one to one availability attack






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






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






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