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 | ftp.log, conn.log, smb_files.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 |
|---|---|
AppLayerProtocolMatch | e.g., FTP/SMB observed over uncommon ports |
OutboundDataRateThreshold | Bytes transferred outside trusted subnets >100MB |
