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 |
|---|---|---|
| WinEventLog:Sysmon | EventCode=23 | DC0040 File Deletion |
| WinEventLog:Security | EventCode=1102 | DC0038 Application Log Content |
| WinEventLog:Sysmon | EventCode=13, 14 | DC0063 Windows Registry Key Modification |
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 |
|---|---|
TimeWindow | Correlate indicator removal within X mins after persistence/setup activities |
TargetFilePathPattern | Customize detection to log file paths or common registry hives |
