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 | http.log, conn.log | DC0085 Network Traffic Content |
| auditd:SYSCALL | outbound connections | DC0082 Network Connection Creation |
| auditd:SYSCALL | execve | DC0032 Process 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 |
|---|---|
HeaderSignatureMatch | Specific HTTP header anomalies or patterns (e.g., spoofed User-Agent). |
UserAgentFingerprint | Flag browser-based sessions |
