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=3, 22 | DC0082 Network Connection Creation |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| etw:Microsoft-Windows-WinINet | HTTPS Inspection | 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 |
|---|---|
TimeWindow | Timeframe for evaluating multiple network connections tied to the same process |
DomainPattern | Regex or string patterns used to identify common Web service infrastructure (e.g., *.googleapis.com) |
PayloadSizeThreshold | Minimum data upload size before flagging anomaly |
ProcessNameExclusionList | Known benign updaters or service processes to reduce false positives |
