MySQL servers should have private endpoints enabled
Private endpoint connections enforce secure communication by enabling private connectivity to Azure Database for MySQL. Configure a private endpoint connection to enable access to traffic coming only from known networks.
Private endpoint connections enforce secure communication by enabling private connectivity to Azure Database for MySQL. Configure a private endpoint connection to enable access to traffic coming only from known networks and prevent access from all other IP addresses, including within Azure.
What this control checks
MySQL servers should have private endpoints enabled
Common pitfalls
Policy effect defaults to AuditIfNotExists
The policy effect defaults to AuditIfNotExists. The allowed values are AuditIfNotExists and Disabled.
Connection must be Approved
The policy looks for Microsoft.DBforMySQL/servers/privateEndpointConnections where privateLinkServiceConnectionState.status equals Approved.
Audit evidence
Evidence that deployed resources meet this control: Azure Policy compliance results for the built-in policy definition "Private endpoint should be enabled for MySQL servers" (7595c971-233d-4bcf-bd18-596129188c49); PowerPipe control azure_compliance.control.mysql_server_private_link_used.
Scans of the Terraform code that flag the same setting before deployment: Checkov check CKV2_AZURE_44.
