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:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=3, 22 | DC0082 Network Connection Creation |
| NSM:Flow | Session Transfer Content | DC0085 Network Traffic Content |
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 |
|---|---|
FileExtensionFilter | Allows tuning of monitored file types (e.g., .jpg, .png, .docx). |
PayloadEntropyThreshold | Threshold for flagging potential hidden data in outbound payloads. |
ExecutionToExfilTimeWindow | Time window between media creation and network transmission. |
