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 |
|---|---|---|
| saas:googleworkspace | access_token issued | DC0007 Web Credential Usage |
| saas:googleworkspace | API access without user login | DC0002 User Account Authentication |
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 |

GeoIPDistanceThreshold | Minimum distance between token reuse events to trigger detection |
