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=4663, 4670, 4656 | DC0061 File Modification |
| WinEventLog:Sysmon | EventCode=13, 14 | DC0063 Windows Registry Key Modification |
| etw:Microsoft-Windows-Kernel-Storage | Raw disk I/O operations bypassing NTFS APIs | DC0004 Firmware Modification |
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 |
|---|---|
MonitoredRegistryKeys | Specify registry paths for mount points and hidden partition configs. |
DiskIOThreshold | Tune thresholds for raw disk access outside expected drivers. |
TimeWindow | Correlate boot-time anomalies with hidden file system mounting activity. |
