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






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






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






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






5. 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






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






8. 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






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






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






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






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






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






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






15. 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






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






17. Attacks against vulnerabilities with no patch or fix






18. 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.






19. 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






20. 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






21. 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






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






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






24. 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






25. 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






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






27. A replica of all allocated data on a disk






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






29. 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






30. 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.






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






32. 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






33. 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






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






36. 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)






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






38. 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






39. 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






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






41. 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






42. 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






43. 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






44. 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






45. 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






46. 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.






47. Detection - containment - eradication - recovery - reporting






48. 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






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






50. Writing the same data on multiple hard disks
