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 | mqtt.log, xmpp.log, amqp.log | DC0085 Network Traffic Content |
Mutable elements

| Field | Description |
|---|---|
BrokerReputationList | Dynamic blocklist or threat intel feed for C2 brokers |
PayloadLengthThreshold | Exfil-style long topic messages vs telemetry-style short messages |
