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






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






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






4. 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






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






6. 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






7. 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






8. A replica of all allocated data on a disk






9. 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






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






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






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






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






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. 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






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






17. 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






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






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






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






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






22. 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






23. Writing the same data on multiple hard disks






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






25. 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






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






27. 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






28. 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)






29. 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.






30. 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






31. 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






32. 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






33. 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






34. 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






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






36. 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






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






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






39. 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






40. 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






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






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






43. 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






44. Detection - containment - eradication - recovery - reporting






45. 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






46. 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






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






48. Attacks against vulnerabilities with no patch or fix






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






50. 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
