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






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






3. 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






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






5. 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






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






7. 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)






8. 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.






9. 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






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. Distributed denial of service - many to one availability attack






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






13. Denial of service - one to one availability attack






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






15. Writing the same data on multiple hard disks






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






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






19. 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






20. 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






21. 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






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






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






24. 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






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






26. 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.






27. 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






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






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






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






31. 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






32. 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






33. A replica of all allocated data on a disk






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






35. 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






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






37. Attacks against vulnerabilities with no patch or fix






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






40. 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






41. 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






42. 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






43. 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






44. 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.






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






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






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






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






49. 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






50. 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
