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






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






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






4. 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






5. 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






6. 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






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






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






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






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






11. 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






12. 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






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






14. 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






15. 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






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






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






18. 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






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






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






21. 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






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






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






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






25. 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






26. Writing the same data on multiple hard disks






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






28. 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






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






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






31. 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






32. 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






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






34. 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.






35. 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






36. Attacks against vulnerabilities with no patch or fix






37. Detection - containment - eradication - recovery - reporting






38. 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)






39. 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






40. 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






41. 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






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






43. Denial of service - one to one availability attack






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






45. 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






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






47. 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






48. 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






49. A replica of all allocated data on a disk






50. 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
