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 | CLI Command Audit | DC0064 Command Execution |
| NSM:Flow | remote access | DC0082 Network Connection Creation |
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 |
|---|---|
Interface | Flags command line access via remote console (telnet/SSH/API) from non-whitelisted source. |
CommandString | Monitors rare/privileged shell commands (e.g., enable, tftp, firmware mod). |
