Log sources and channels
Exactly as MITRE states them in x_mitre_log_source_references. Where a channel is vague, it is vague in the source; kevmap does not tidy it.
| Log source | Channel | Data component |
|---|---|---|
| NSM:Flow | http.log, ssl.log, websocket.log | DC0085 Network Traffic Content |
Mutable elements
Parameters MITRE marks as environment-specific. These are the knobs you are expected to tune; they are why an analytic is not a rule.
| Field | Description |
|---|---|
HeaderEncodingPattern | Base64, hex, or UTF-16 encoding in URI, cookie, or host |
TLSFingerprintMismatch | JA3 hash deviation from known clients |
