| Log source | Channel | Data component |
|---|---|---|
| azure:signinlogs | Failure Reason + UserPrincipalName | DC0002 User Account Authentication |

| Field | Description |
|---|---|
GeoIPAnomalyCheck | Use geolocation mismatches to strengthen signal |
FailedUserRatio | Proportion of total user base affected to filter noise |
