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. Detection - containment - eradication - recovery - reporting






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






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






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






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






6. 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






7. 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






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






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






10. 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






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






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






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






15. 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






16. 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.






17. 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






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






19. 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






20. 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






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






22. 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






23. 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






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






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






26. 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






27. 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






28. 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






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






30. 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






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






32. Attacks against vulnerabilities with no patch or fix






33. 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






34. 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.






35. 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






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






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






38. 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






39. 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






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






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






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






43. Denial of service - one to one availability attack






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






45. 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)






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






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






49. 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






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