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 |
|---|---|---|
| auditd:SYSCALL | execve calls with high-frequency or known bandwidth-intensive tools | DC0032 Process Creation |
| NSM:Flow | large outbound data flows or long-duration connections | DC0078 Network Traffic Flow |
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 |
|---|---|
ToolPattern | Can be tuned for specific bandwidth abuse tools (e.g., proxychains, 3proxy). |
TrafficRateThreshold | Baseline deviation thresholds must be environment-specific. |
