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:Microsoft-Windows-Backup | Windows Backup Catalog deletion or catalog corruption | DC0040 File Deletion |
| WinEventLog:System | Service stopped or RecoveryDisabled set via REAgentC | DC0041 Service Metadata |
| 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 |
|---|---|
TimeWindow | Used to track rapid recovery feature changes over short intervals |
CommandLinePattern | Can be tuned to catch variations in destructive flags (/all, /quiet, -delete) |
ParentProcessContext | Tune based on common parent-child chains (e.g., powershell → diskshadow) |
