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 | socket/connect | DC0078 Network Traffic Flow |
| linux:syslog | Multiple NXDOMAIN responses and high entropy domains | DC0085 Network Traffic Content |
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 |
|---|---|
NXDOMAINThreshold | Ratio of failed queries triggering alert (e.g., >40%) |
DomainAge | Flag queries to domains registered in last 7–30 days |
