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 | Application errors or resource contention from excessive frontend or script invocation | DC0038 Application Log Content |
| macos:osquery | Rapid spawning of resource-heavy applications (e.g., Preview, Safari, Office) | 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 |
|---|---|
SpinReportCount | Threshold for number of system spin/crash reports in a defined window. |
HeavyAppReopenRate | Frequency of user or script reopening GUI-heavy apps. |
