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=10 | DC0035 Process Access |
| WinEventLog:Security | EventCode=4663, 4670, 4656 | DC0055 File Access |
| WinEventLog:System | EventCode=7045 | DC0060 Service Creation |
| 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 |
|---|---|
TargetImage | Scope to sensitive GUI/session processes like winlogon.exe or osk.exe |
AccessMask | Can be tuned to 0x1fffff for full-access injection detection |
TimeWindow | Tunable for sustained polling or multiple registry edits in short succession |
