  • 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. 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






2. 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






3. 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






4. 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






5. Writing the same data on multiple hard disks






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






7. 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






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






9. 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






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






11. 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






12. 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






13. 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






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






15. 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






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






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






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






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






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






21. 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






22. 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






23. 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






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






25. 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






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






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






28. Detection - containment - eradication - recovery - reporting






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






30. 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






31. 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






32. 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






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






34. 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.






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






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






37. 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.






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






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






40. 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






41. 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






42. 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






43. 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






44. Denial of service - one to one availability attack






45. 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






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






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






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






49. 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






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