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=11 | DC0039 File Creation |
| WinEventLog:Security | EventCode=4688 | 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 |
|---|---|
DataVolumeThresholdMB | Set threshold for outbound volume (e.g., >50MB in a single connection). |
ProtocolAllowList | Allow-listed protocols in use for specific machines or users (e.g., FTP allowed for backups). |
TimeWindow | Define allowed time-of-day windows (e.g., flag after-hours file transfer). |
ParentProcessAnomaly | Identify anomalous parent-child process relationships (e.g., `winword.exe` spawning `ftp.exe`). |
