Which of the following wireless security tools is used to protect the integrity of data in a wireless frame?

(A) MIC
(B) WIPS
(C) WEP
(D) EAP

MIC is the correct answer.

A message integrity check (MIC) is a security tool that can protect against data tampering. You can think of a MIC as a way for the sender to add a secret stamp inside the encrypted data frame. The stamp is based on the contents of the data bits to be transmitted. Once the recipient decrypts the frame, it can compare the secret stamp to its own idea of what the stamp should be, based on the data bits that were received. If the two stamps are identical, the recipient can safely assume that the data has not been tampered with.
