Comptia Security +: Vocab

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.

3. Entails planning and system actions to ensure that a project is following good quality management practices






4. The user






5. A legal term used to describe an out-of-court statement offered to establish the truth of the facts asserted in that statement. Hearsay is generally not admissible in common law courts because it is of dubious value - but there are many exceptions to






6. A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met.






7. A denial-of-service attack is an attack on a computer system or network that causes a loss of service to users - typically the loss of network connectivity and services by consuming the bandwidth of the victim network or overloading the computational






8. The attacker sends a SYN request to the victims machine and the victim machine allocates resources for that request and sends a SYN/ACK back. The attacking machine doesn't respond however - but instead sends another SYN and continues to do so until t






9. The physical part of a computer - as distinguished from the computer software that executes within the hardware.






10. The intercepting of conversations by unintended recipients






11. In cryptography - it is a block cipher






12. Countermeasure to put fake stuff into a database so if someone is reading it they will get the wrong info.






13. Provides for less data leakage. Longer distance. Uses light instead of electrical impulse.






14. A hidden communications channel on a system that allows for the bypassing of the system security policy






15. In a distributed attack - the attacking computer hosts are often zombie computers with broadband connections to the Internet that have been compromised by viruses or Trojan horse programs that allow the perpetrator to remotely control the machine and






16. In a computer system (or cryptosystem or algorithm) these are methods of bypassing normal authentication or securing remote access to a computer - while attempting to remain hidden from casual inspection.






17. When two or more processes are linked and execute multiple programs simultaneously






18. A war dialing utility






19. The output of a hash function is a digest.






20. When you know something from a source - and can infer other related information based off of what you know - when you may not necessarily have access to that data normally.






21. An AAA (Authentication - Authorization - and Accounting) protocol for applications such as network access or IP mobility. It is intended to work in both local and roaming situations.






22. In computing - the Challenge-Handshake Authentication Protocol authenticates a user to an Internet access provider. CHAP provides protection against playback attack by the peer through the use of an incrementally changing identifier and of a variable






23. Degaussing is the process of reducing or eliminating an unwanted magnetic field. The Degausser is what actually performs the degaussing.






24. A site that is ready and available within minutes or hours to continue processing. This is a site that is fully configured and ready to go.






25. Residual physical representation of data that has been in some way erased. After storage media is erased there may be some physical characteristics that allow data to be reconstructed.






26. When an employee leaves the company - you want to make them aware of non-disclosures and non compete clauses - etc.






27. A meme and a joke are the same thing. e.g. When someone says to delete a file that is really just fine and they call it a virus






28. Project initiation - functional design analysis and planning - system design specifications - software development - installation/implementation - operational/maintenance - disposal






29. Accepting all packets






30. Rolling command center with UPS - satellite - uplink - power - etc.






31. A military standard defining controls for emanation protection






32. Basic Input/Output System






33. Trusted Computing Base. Comprised of the hardware - software - and firmware of the system.






34. A component in the Wireless Application Protocol (WAP) protocol stack. It sits between the WTP and WDP layers in the WAP communications stack.






35. Providing verification to a system






36. A remote authentication protocol that is used to communicate with an authentication server commonly used in UNIX networks. TACACS allows a remote access server to communicate with an authentication server in order to determine if the user has access






37. CISSPs subscribe to a code of ethics for building up the security profession






38. In computer networking - this is the method for finding a host's hardware address when only its IP address is known. Due to the overwhelming prevalence of IPv4 and ethernet - ARP is primarily used to translate ethernet MAC addresses from IP addresses






39. An attempt to trick the system into believing that something false is real






40. The key that is used to encrypt a file or message is the same key that is used to decrypt the file or message






41. When one key of a two-key pair has more encryption pattern than the other






42. In cryptanalysis - a brute force attack is a method of defeating a cryptographic scheme by trying a large number of possibilities. In most schemes - the theoretical possibility of a brute force attack is recognised - but it is set up in such a way th






43. Ethernet - Cat5 - Twisted to allow for longer runs.






44. This is an open international standard for applications that use wireless communications.






45. When a security event occurs - this is the order in which people will be contacted. This is a predefined list.






46. Confidentiality - Integrity - and Availability






47. In computer security - this type of attack is a situation in which one person or program successfully masquerades as another by falsifying data and thereby gains an illegitimate advantage.






48. Continuation of Operations Plan






49. RFC 1918 defined the following addresses as the private addressing ranges: 192.168.x.x - 10.x.x.x - 172.16.x.x - 172.31.x.x






50. An arrangement in which the keys needed to decrypt encrypted data are held in escrow by a third party - so that someone else (typically government agencies) can obtain them to decrypt messages which they suspect to be relevant to national security.
