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:endpointsecurity | ES_EVENT_TYPE_NOTIFY_EXEC | DC0032 Process Creation |
| macos:unifiedlog | tcp/udp | DC0078 Network Traffic Flow |
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 |
|---|---|
UserContext | Detect activity outside normal user behavior (e.g., automation or daemon context) |
EntropyScore | Optional for detecting encoded payloads delivered via stage 1 |
