What does MIC stand for?

| Type | Initialism |
The initialism MIC stands for Message Integrity Check in the cited Cisco management-frame protection documentation. The term concerns integrity information associated with a frame in that technical context.
Keep the protocol and vendor context when expanding MIC. Cisco’s2008 infrastructure MFP document describes a Message Integrity Check added before the Frame Check Sequence, or FCS; those named fields should not be merged. The document also distinguishes adding integrity information from validating a received frame and reporting a discrepancy. That sequence helps read a diagnostic note without overstating it. A fictional trace containing a field labelled MIC has supplied field presence, not necessarily a recorded successful validation. If another line explicitly reports invalid MIC, retain that outcome and its frame context. The abbreviation alone does not identify the reason for an error or prove which device or person caused it. This guide uses the dated document to explain naming and recorded states, not to recommend current network configuration. Other specifications use Message Integrity Code for MIC, so expand the term according to the actual reference rather than rewriting every occurrence to one universal phrase.
Meaning in context
- Message Integrity Check
- The MIC wording used by the cited Cisco MFP document.
- FCS distinction
- The document names Frame Check Sequence separately from the MIC.
Practical examples
Do not turn presence into success
- Before
Invented trace: MIC field present; validation outcome not recorded. Draft: Integrity validation passed.
- After
The fictional trace contains a MIC field; no validation outcome is supplied.
The field’s presence and the result of a validation operation are separate evidence.
Keep the supplied error
- Before
Invented trace: frame Cedar, invalid MIC reported; cause not determined. Draft: A named attacker definitely modified the frame.
- After
The fictional trace reports invalid MIC for frame Cedar; no cause or actor is identified.
The rewrite retains the error while leaving the missing attribution open.
Original illustrative examples, not quotations or reports of actual events.
Read the frame-validation evidence
Does a frame note show integrity-field presence, validation or only a different frame-check field?

Message Integrity Check in this Cisco MFP context.
Read a trace
Separate field presence from validation outcome.
MIC is present; the result is not recorded.
Report an error
Retain the frame and actual outcome without inventing an actor.
Invalid MIC was reported for the supplied frame.
Preserve the protocol’s exact expansion and distinguish a present MIC field, a reported validation outcome and the separate FCS field.
