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 |
|---|---|---|
| macos:unifiedlog | Rapid domain-to-IP resolution changes for same domain | DC0078 Network Traffic Flow |
| macos:unifiedlog | Unexpected apps generating frequent DNS queries | 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 |
|---|---|
DNSRotationRate | Rate of IP churn per domain to trigger detection |
NewDomainThreshold | Flag if domain was registered recently (e.g., < 30 days) |
