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 |
|---|---|---|
| auditd:SYSCALL | ioctl/write: Direct firmware update or device memory manipulation syscalls | DC0004 Firmware Modification |
| linux:syslog | Driver load events or firmware load failures for hardware devices | DC0079 Driver Load |
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 |
|---|---|
FirmwareImageBaseline | Baseline firmware checksums for comparison |
AlertThresholds | Tolerance levels for SMART errors before triggering alerts |
