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. 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






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






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






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






6. 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






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






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






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






10. 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






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






12. 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






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






14. 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






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






16. 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






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






18. 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






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






20. 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






21. 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






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






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






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. 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






26. 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






27. 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






28. 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






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






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






31. Detection - containment - eradication - recovery - reporting






32. 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






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






34. 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)






35. 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






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






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






38. 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.






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






40. 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






41. 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






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






43. Attacks against vulnerabilities with no patch or fix






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






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






46. 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






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






48. 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






49. 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






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