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. Attacks against vulnerabilities with no patch or fix






2. 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.






3. 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






4. Denial of service - one to one availability attack






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






6. 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






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






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






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






10. 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






11. Detection - containment - eradication - recovery - reporting






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






13. 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






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






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






16. 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






17. 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






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. 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






20. 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






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






22. 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






23. 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






24. 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.






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






26. 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






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






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






29. Writing the same data on multiple hard disks






30. 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






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






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






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






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






37. 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






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






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






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






41. 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






42. 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






43. 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






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






45. 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






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






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






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






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