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. 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






2. 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






3. 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






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






5. Denial of service - one to one availability attack






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






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






8. 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






9. 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






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






11. 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






12. 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.






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






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






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






16. 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






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






18. 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






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






20. 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






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






22. 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






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






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






25. 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






26. 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






27. 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






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






29. 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.






30. 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






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






32. 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






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






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






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






36. Attacks against vulnerabilities with no patch or fix






37. 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






38. Detection - containment - eradication - recovery - reporting






39. 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






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






41. 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






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






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






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






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






46. 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






47. 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






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






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






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