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 |
|---|---|---|
| networkdevice:syslog | Image Upgrade / Configuration Change | DC0004 Firmware Modification |
| NSM:Flow | packet capture or DPI logs | DC0085 Network Traffic Content |
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 |
|---|---|
FirmwareVersion | Baseline hash or expected version for config/image integrity |
Protocol | Scope to plaintext channels or low-assurance SSH versions |
