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






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






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






4. 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






5. 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






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






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






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. 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






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






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






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






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






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






15. Denial of service - one to one availability attack






16. 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






17. 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






18. 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






19. 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






20. 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.






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






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






23. 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






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






25. 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






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






27. 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






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






29. 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.






30. 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






31. 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






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






33. Detection - containment - eradication - recovery - reporting






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






35. 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






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






37. 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






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






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






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






42. 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






43. 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






44. 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






45. 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






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






47. 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)






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. Distributed denial of service - many to one availability attack






50. 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
