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 | High entropy domain queries with multiple NXDOMAINs | DC0078 Network Traffic Flow |
| macos:unifiedlog | Unexpected apps performing repeated DNS lookups | 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 |
|---|---|
ReputationFeedWhitelist | Exclude trusted CDN and cloud provider domains |
LexicalScoreThreshold | Adjust score for word-based vs. letter-based DGAs |
