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.

25. In cryptanalysis - this attack is a method of defeating a cryptographic scheme by trying a large number of possibilities; for example - exhaustively working through all possible keys in order to decrypt a message. In most schemes - the theoretical po






26. 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






27. A collection of updates - fixes and/or enhancements to a software program delivered in the form of a single installable package.






28. In cryptography - a substitution cipher is a method of encryption by which units of plaintext are substituted with ciphertext according to a regular system; the 'units' may be single letters (the most common) - pairs of letters - triplets of letters






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






30. Threat to physical security.






31. Network Address Translation






32. In cryptography - it is one of the simplest and most widely-known encryption techniques. It is a type of substitution cipher in which each letter in the plaintext is replaced by a letter some fixed number of positions further down the alphabet.






33. An attacker spoofs the source IP in a packet header - to make a ping request appear to have originated from the future victim's network - then the responding network responds in full force to these requests and brings down the victim's network.
