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. 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






2. A replica of all allocated data on a disk






3. 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






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






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






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






7. 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






8. 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






9. Detection - containment - eradication - recovery - reporting






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






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






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






14. 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






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






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






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






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






19. 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






20. 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






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






22. 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






23. 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.






24. 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






25. 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






26. 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






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






28. 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






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






30. Denial of service - one to one availability attack






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






32. Writing the same data on multiple hard disks






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






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






35. 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






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






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






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






39. 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






40. 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






41. 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






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. Two parties conspire to undermine the security of the transaction






44. 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






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






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. 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






48. 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






49. 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






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