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=1 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Security | EventCode=4663, 4670, 4656 | DC0055 File Access |
| WinEventLog:System | EventCode=1006, 10001 | DC0042 Drive 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 |
|---|---|
DriveTypeFilter | Filter on removable (e.g., USB) drives only. |
ProcessNameExclusionList | Exclude known, approved backup or sync utilities. |
TimeWindow | Limit correlation of file access and device mount to a defined window (e.g., <5 minutes). |
