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 means to achieve data redundancy without incurring the same degree of cost as that of mirroring in terms of disk usage and write performance






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






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






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






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






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






8. 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






9. 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






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






11. 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






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






13. 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






14. 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






15. 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






16. Writing the same data on multiple hard disks






17. A replica of all allocated data on a disk






18. 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






19. 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






20. 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






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






22. 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.






23. Detection - containment - eradication - recovery - reporting






24. Denial of service - one to one availability attack






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






26. 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






27. 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.






28. 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






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






30. 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)






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






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






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






34. 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






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






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






37. 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






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






39. 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






40. Attacks against vulnerabilities with no patch or fix






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






42. 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






43. 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






44. 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






45. 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






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






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






48. 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






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






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