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






2. 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






3. 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






4. 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






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






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






7. 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






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






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






10. 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






11. 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






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






13. 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






14. 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






15. 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






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






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






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






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






20. 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






21. 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






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






23. 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






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






25. 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






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






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






28. Writing the same data on multiple hard disks






29. 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






30. 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






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






32. 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






33. 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.






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






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






36. 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






37. 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






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






39. Attacks against vulnerabilities with no patch or fix






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






41. A replica of all allocated data on a disk






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






43. 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






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






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






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






47. 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






48. 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






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






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