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. 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






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






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






4. 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)






5. 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






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






7. 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.






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






9. 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






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






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






12. 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.






13. 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






14. 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






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






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






17. 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






18. 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






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






20. A replica of all allocated data on a disk






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






22. Detection - containment - eradication - recovery - reporting






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






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






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






26. 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






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






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






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






30. Denial of service - one to one availability attack






31. 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






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






33. Attacks against vulnerabilities with no patch or fix






34. 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






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






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






37. 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






38. 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






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






40. 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






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






42. 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






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






44. 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






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






46. 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






47. 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






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






49. 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






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