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






2. A replica of all allocated data on a disk






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






4. Attacks against vulnerabilities with no patch or fix






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






6. 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






7. 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






8. 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






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






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






11. 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






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






13. 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






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






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. Denial of service - one to one availability attack






17. 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.






18. 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






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. An offline technique in which the attacker has gained access to the password hashes or database






21. 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






22. 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






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






24. 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






25. 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






26. 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






27. 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






28. 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






29. 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






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






31. 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






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. 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.






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






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






36. 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






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






38. 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






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






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






41. 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






42. 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)






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






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






45. 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.






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






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






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






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






50. 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
