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=11 | DC0039 File Creation |
| WinEventLog:Security | EventCode=5145 | DC0102 Network Share Access |
| 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 |
|---|---|
FilePathRegex | Regex for matching key file extensions (.pem, .pfx, .ppk, etc.) or known certificate directories like C:\Users\*\.ssh\ |
ParentProcessName | Set of known benign certificate management tools to exclude (e.g., certutil.exe, ssh.exe) |
