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 |
| NSM:Flow | SSL/TLS Inspection or PCAP | 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 |
|---|---|
ProcessName | To tune for unexpected or uncommon executables initiating network connections |
DataTransferThreshold | Volume of outbound data in short time window (e.g., >1MB in <5 min) |
TimeWindow | Look for connections persisting outside of normal business hours |
