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:System | EventCode=7035 | DC0041 Service Metadata |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| WinEventLog:Sysmon | EventCode=6 | DC0079 Driver Load |
| WinEventLog:Security | EventCode=4688 | DC0032 Process 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 |
|---|---|
CrashCorrelationWindow | Time between suspicious interaction and security service failure |
ProtectedServiceList | Security agents/services expected to remain stable |
TelemetryGapThreshold | Acceptable heartbeat silence duration |
