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 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






2. 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






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






4. 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






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






6. 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






7. 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.






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






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






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






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






12. 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






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






14. 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






15. 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






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. 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






18. 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






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






20. 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)






21. 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






22. 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






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






24. Detection - containment - eradication - recovery - reporting






25. 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






26. 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






27. 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






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






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






30. 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






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






32. 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






33. A replica of all allocated data on a disk






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






35. 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






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






37. 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






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






39. Attacks against vulnerabilities with no patch or fix






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






41. 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






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






43. 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






44. 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






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






46. 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






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






48. 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






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






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