 == Setting the minimum and maximum protocol versions
 
-If your environment has specific requirements for encrypted traffic in your service mesh, you can control the cryptographic functions that are allowed by setting the `spec.istio.global.tls.minProtocolVersion` or `spec.istio.global.tls.maxProtocolVersion` in your `ServiceMeshControlPlane` resource. Those values, configured in your control plane resource, define the minimum and maximum TLS version used by mesh components when communicating securely over TLS.
