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:System | EventCode=5005 (WLAN), EventCode=302 (Bluetooth) | DC0085 Network Traffic Content |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File 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 |
|---|---|
InterfaceType | Filter for specific interface categories (e.g., WiFi, Bluetooth, 4G). |
FileSizeThreshold | Tunable for environment-specific large file access events pre-transfer. |
TimeWindow | Temporal correlation window for file read followed by network activity. |
