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. 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






2. 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






3. 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






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






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






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






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






8. 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






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






10. Attacks against vulnerabilities with no patch or fix






11. 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






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






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






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






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






16. 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






17. 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






18. 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






19. 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






20. 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






21. 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)






22. 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






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






24. 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.






25. 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






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






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






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






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






30. 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






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






32. 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






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






34. 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






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






36. 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






37. 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.






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






40. 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






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






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






43. 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






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






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






46. A replica of all allocated data on a disk






47. Detection - containment - eradication - recovery - reporting






48. 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






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






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