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 |
|---|---|---|
| Firewall Audit Logs | Config Change | DC0051 Firewall Rule Modification |
| NSM:Flow | Inter-segment traffic | DC0078 Network Traffic Flow |
| networkdevice:cli | Policy Update | DC0064 Command Execution |
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 |
|---|---|
ProxyTarget | Internal subnets or endpoint roles allowed for port forwarding. |
ConfigChangeUser | Detect changes made outside scheduled or authorized windows. |
FlowThreshold | Volume of data relayed through proxy exceeds historical norms. |
