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:cli | CLI command logs | DC0064 Command Execution |
| networkdevice:syslog | flow records | DC0078 Network Traffic Flow |
| NSM:Flow | PCAP inspection | 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 |
|---|---|
ProtocolCommandWatchlist | Flag commands like `copy`, `archive tar`, or `upload` directed at external hosts. |
DestinationIPBlocklist | Define external IP ranges unauthorized to receive router/switch configs. |
