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 | exec rm -rf|dd if=/dev|srm|file unlink | DC0040 File Deletion |
| macos:unifiedlog | process.*exit.*code | DC0033 Process Termination |
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 |
|---|---|
CommandPattern | Focus on high-risk patterns in temporary directories or key system paths. |
EntropyChangeRate | Optional anomaly detection on overwritten files with high-entropy payloads. |
