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. 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






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






3. 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






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






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






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






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






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






9. 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






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






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






12. 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






13. 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






14. 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






15. 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






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






17. 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






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






19. 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






20. 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






21. A replica of all allocated data on a disk






22. 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






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






24. 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






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






26. Denial of service - one to one availability attack






27. 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






28. 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






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






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






31. 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






32. 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






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






34. 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






35. 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






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






37. 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






38. 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






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






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






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






42. 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.






43. 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






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






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. The actors causing the threats that might exploit a vulnerability






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






48. Attacks against vulnerabilities with no patch or fix






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






50. 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
