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:spawn | DC0032 Process Creation |
| fs:fsusage | file write | DC0039 File 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 |
|---|---|
FileSizeThresholdMB | Padded binary threshold for file size |
TimeWindow | Detection correlation window for execution after file creation |
UserContext | Filters for specific users or groups such as admin or service accounts |
