+###### Warning
+
+The AWS account root user of the account that owns the cluster always retains full access to its own resources, regardless of resource-based policy conditions, including VPC source restrictions. Resource-based policies don't restrict access for the root user. To limit root user access to your clusters, use IAM identity-based policies or avoid using root credentials for database connections. For more information, see [Root user best practices for your AWS account](https://docs.aws.amazon.com/IAM/latest/UserGuide/root-user-best-practices.html).
