Description
Indicates whether your client adapter is using message integrity check
(MIC) to protect packets sent to and received from the access point.
MIC prevents bit-flip attacks on encrypted packets. During a bit-flip
attack, an intruder intercepts an encrypted message, alters it slightly,
and retransmits it, and the receiver accepts the retransmitted message
as legitimate.
