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 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






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






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






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






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






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






7. 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






8. 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






9. 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






10. 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






11. 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






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






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






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






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






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. Detection - containment - eradication - recovery - reporting






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






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






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






21. A replica of all allocated data on a disk






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






23. 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






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






25. 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.






26. 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.






27. 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






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 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






30. 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






31. Term used for malware that is focused on hiding its own existence. Typical capabilities include file - folder - process - and network connection hiding. The techniques developed with rootkits are now commonly included in other types of malware






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






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






34. Attacks against vulnerabilities with no patch or fix






35. 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






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






37. Denial of service - one to one availability attack






38. 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






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






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






41. 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






42. 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






43. 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.






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






45. 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






46. 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






47. Writing the same data on multiple hard disks






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






49. 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






50. 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
