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. 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






2. 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






3. 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






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






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






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






7. 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






8. 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






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






10. A replica of all allocated data on a disk






11. 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






12. 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






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






14. 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






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. Denial of service - one to one availability attack






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






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






19. 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






20. 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






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






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






23. 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






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






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






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






27. 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.






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






29. 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






30. Writing the same data on multiple hard disks






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






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






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






34. 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






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






36. 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






37. 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






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. 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






40. 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






41. 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






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






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






44. 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






45. 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.






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






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






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






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






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