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 |
|---|---|
SuspiciousParentProcesses | Non-standard binaries launching PowerShell or netstat (e.g., winword.exe spawning powershell.exe). |
TimeWindow | Correlates discovery behavior before lateral movement or credential access. |
CommandPatternList | Regex or keyword patterns to match discovery utilities (e.g., `netstat`, `Get-NetTCPConnection`). |
