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:PowerShell | EventCode=4103, 4104, 4105, 4106 | DC0064 Command Execution |
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 |
|---|---|
ParentProcessContext | Identify if enumeration originates from non-interactive shell or system service |
TimeWindow | Tune temporal grouping of enumeration + lateral movement attempts |
UserContext | Flag unexpected users issuing enumeration commands (e.g., service accounts) |
