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. 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






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






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






4. 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






5. 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






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






7. 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






8. 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






9. 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






10. 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






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






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






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






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. 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






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






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






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. 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






20. 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






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






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. Places the attacker between the victim and another system. the attackers goal is to be able to serve as an undiscovered proxy for either or both of two endpoints engaging in communication. Uses sniffing and spoofing. The capabilities of session hijac






24. 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






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






26. Writing the same data on multiple hard disks






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






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






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






30. 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






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






32. 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






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






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






35. 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






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






37. 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






38. 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






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






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






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






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






43. 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






44. A replica of all allocated data on a disk






45. Striped set with dedicated parity at the block level - employs a dedicated parity drive rather than having parity data distributed amongst all disks. allows for data recovery in the event that one disk fails






46. Denial of service - one to one availability attack






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






48. Detection - containment - eradication - recovery - reporting






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






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