The above policies reject unauthenticated traffic at the ztunnel unless its destination is port 9090. For more complete examples, read through the [test cases](../../pilot/pkg/serviceregistry/kube/controller/ambientindex_test.go) in the `TestRBACConvert` function.

#### Select a specific configuration profile

The simplest customization is to select a profile different to `default` e.g. `minimal`. See [manifests/profiles/minimal.yaml](../manifests/profiles/minimal.yaml):

```yaml
# minimal-install.yaml
apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
