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:Security | EventCode=4688 | DC0032 Process Creation |
| WinEventLog:Security | EventCode=4663, 4670, 4656 | DC0055 File Access |
| 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 |
|---|---|
FileSizeThresholdMB | Threshold size in MB to determine suspicious padding |
TimeWindow | Correlation time window between file creation and execution |
UserContext | Scope the detection to suspicious or non-standard user accounts |
