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. Two parties conspire to undermine the security of the transaction






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






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






4. 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






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






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. Denial of service - one to one availability attack






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






9. 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






10. 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






11. 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.






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






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






14. 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






15. 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






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. 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






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






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






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






21. 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






22. 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






23. 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)






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






25. 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






26. Detection - containment - eradication - recovery - reporting






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






28. 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






29. 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






30. 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






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






32. 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






33. 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






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






35. Attacks against vulnerabilities with no patch or fix






36. 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






37. 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






38. 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






39. 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






40. 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






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






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






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






44. 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






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






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






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






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






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






50. 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
