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






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






3. 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






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






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






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






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






8. Denial of service - one to one availability attack






9. 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






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






11. 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






12. 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






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






14. 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






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






16. 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






17. 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.






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






19. 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






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






21. 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






22. 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






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






24. 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






25. 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






26. 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






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






28. 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






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






30. Detection - containment - eradication - recovery - reporting






31. 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






32. 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






33. DOS - resource exhaustion - most basic type of resource exhaustive attacks - and involve an attacker - or attacker controlled machines - initiating many connections to the victim - but not responding to the victim's SYN/ACK packets. The victim's conn






34. 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






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






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






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






38. 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






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






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






41. Writing the same data on multiple hard disks






42. 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






43. 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






44. A replica of all allocated data on a disk






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






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






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






48. 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






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






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