Test your basic knowledge |

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. 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






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






3. Attacks against vulnerabilities with no patch or fix






4. 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






5. 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






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






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






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






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






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






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






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






14. 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






15. 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






16. 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






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






18. 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






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






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






21. 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






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






23. Detection - containment - eradication - recovery - reporting






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






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






26. 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.






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






28. Denial of service - one to one availability attack






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






30. 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)






31. 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






32. 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






33. 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.






34. 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






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






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






37. 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






38. 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






39. 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






40. 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






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






42. 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






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






44. 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






45. 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






46. Writing the same data on multiple hard disks






47. 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






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






49. 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






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