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:Security | EventCode=4723, 4724, 4740 | DC0010 User Account Modification |
| WinEventLog:Sysmon | EventCode=1 | 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 |
|---|---|
UserContext | Account performing the operation (e.g., Domain Admins vs. local users) |
TimeWindow | Alert only on actions outside of maintenance windows |
ParentProcessName | Detect suspicious process lineage (e.g., powershell.exe launching net.exe) |
