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 | process, network | DC0085 Network Traffic Content |
| macos:endpointsecurity | exec events | DC0032 Process Creation |

| Field | Description |
|---|---|
UserContext | Flag unexpected outbound activity from non-admin or system users |
