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 | shutdown -h now or reboot | DC0032 Process Creation |
| macos:unifiedlog | System shutdown or reboot requested | DC0018 Host Status |
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 |
|---|---|
LaunchMechanism | Scripted vs interactive shutdowns. |
LogGranularity | May vary depending on macOS version and unified log verbosity. |
