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=11 | DC0039 File Creation |
| WinEventLog:Sysmon | EventCode=1 | DC0032 Process Creation |
| EDR:file | File Metadata Analysis (PE overlays, entropy) | DC0059 File Metadata |
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 |
|---|---|
OverlaySizeThreshold | Threshold in bytes where appended sections to binaries are considered suspicious |
ProcessTreeDepth | Controls how far child process lineage is analyzed for dropped embedded payloads |
TimeWindow | Defines correlation interval between file write and process execution |
