  * mTLS communication between Envoy proxies;
  * regular TLS on the downstream and the upstream of Envoy proxies (e.g. gateway);

  * Istiod xDS server;
  * Istiod injection and validation webhook servers.

### Server

#### Server CLI

A CLI client is available using the `server` binary.

Usage examples:

```shell
go install ./pkg/test/echo/cmd/server
# Serve on port 15008 (default) with TLS

issue:
  - 33809
releaseNotes:
  - |
    **Added** Auto mTLS support for workload level peer authentication. You no longer need to configure destination rule when servers are configured with workload level peer authentication policy. This can be disabled by setting ENABLE_AUTO_MTLS_CHECK_POLICIES to "false".
