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 |
|---|---|---|
| macos:unifiedlog | outbound TCP/UDP traffic over unexpected port | DC0078 Network Traffic Flow |
| macos:unifiedlog | launchd services binding to non-standard ports | DC0032 Process Creation |
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 |
|---|---|
BaselinePortProfiles | Define expected macOS service port usage (e.g., AirDrop, Bonjour). |
