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. 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






2. 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.






3. 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






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






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






6. 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






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






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






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






10. 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






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






12. 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






13. 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)






14. 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






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






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






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






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






19. 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






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






21. 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






22. 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






23. 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.






24. 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






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






26. 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






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






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






29. 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






30. 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






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






32. 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






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






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






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






36. 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






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






38. Attacks against vulnerabilities with no patch or fix






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






40. DOS - Malformed packet - denial of service involved in sending a malformed ICMP echo request (ping) that was larger than the maximum size of an IP packet. Patching TCPIP stacks of systems removed the vulnerability of this DOS attack






41. A replica of all allocated data on a disk






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






43. 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






44. 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






45. 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






46. 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






47. 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






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






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






50. 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
