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 | 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 |
|---|---|
CommandLinePatternMatch | curl or wget in scripts with suspicious domains or silent flags |
BeaconIntervalWindow | Fixed-timed HTTP callbacks with 60±5s jitter |
