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 |
|---|---|---|
| NSM:Flow | Unexpected route changes or duplicate gateway advertisements | DC0078 Network Traffic Flow |
| networkdevice:config | Configuration file modified or replaced on network device | DC0061 File 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 |
|---|---|
RoutingPolicyBaseline | Expected routing and BGP/OSPF paths for validation. |
FirmwareChecksum | Baseline image checksum per device type used to detect tampering. |
