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. 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






2. 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)






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






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






5. 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






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






7. 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






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






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






10. 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






11. 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






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. 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






14. 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






15. 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






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






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






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






19. 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






20. Writing the same data on multiple hard disks






21. 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






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






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






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






26. 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






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






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






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






30. 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






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






32. Denial of service - one to one availability attack






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






34. 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






35. 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






36. 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






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






38. Attacks against vulnerabilities with no patch or fix






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






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






41. 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






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






43. A replica of all allocated data on a disk






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






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






46. 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.






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






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






49. 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






50. 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
