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:System | EventCode=8001 | DC0082 Network Connection Creation |
| WinEventLog:Sysmon | EventCode=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=1 | 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 |
|---|---|
TimeWindow | Defines how quickly a file access and Bluetooth activity must occur to be correlated. |
InterfaceType | May focus on Bluetooth-specific interfaces or drivers like 'bthport.sys'. |
FileSizeThreshold | Tune to trigger only on significant exfiltratable file reads. |
