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=9 | DC0054 Drive Access |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File 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 |
|---|---|
KnownGoodMBRHashes | Baseline hashes of clean MBR/VBR sectors for comparison |
ESPFileWhitelist | Approved EFI executables within ESP directories |
TimeWindow | Correlation window between privileged access, raw disk modification, and EFI file creation |
