# Configure the TLS version
Elastic Cloud Enterprise 2.4.0 and later defaults to minimum TLS version 1.2 with a modern set of cipher suites.

| Elastic Cloud Enterprise version | Default minimum TLS version | Default allowed cipher suites                                                                                                                                                                                                                                                                                                                                                                                                        |

You can bring back the legacy behavior by running the following script. Note that this requires a proxy restart.
1. On a host that holds the director role:
   ```sh
   docker run \
   -v ~/.found-shell:/elastic_cloud_apps/shell/.found-shell \
   --env SHELL_ZK_AUTH=$(docker exec -it frc-directors-director bash -c 'echo -n $FOUND_ZK_READWRITE') $(docker inspect -f '{{ range .HostConfig.ExtraHosts }} --add-host {{.}} {{ end }}' frc-directors-director)  \
   --env FOUND_SCRIPT=setIntermediateTls.sc \
   --rm -it \
   $(docker inspect -f '{{ .Config.Image }}' frc-directors-director) \
   /elastic_cloud_apps/shell/run-shell.sh
   ```
2. On all of the proxy hosts:
   ```sh
   docker rm -f frc-proxies-proxyv2
   ```

To reset back to the default behavior of using TLSv1.2 and a modern cipher suite, you can run the following code.
1. On a host that holds the director role:
   ```sh
   docker run \
   -v ~/.found-shell:/elastic_cloud_apps/shell/.found-shell \
   --env SHELL_ZK_AUTH=$(docker exec -it frc-directors-director bash -c 'echo -n $FOUND_ZK_READWRITE') $(docker inspect -f '{{ range .HostConfig.ExtraHosts }} --add-host {{.}} {{ end }}' frc-directors-director)  \
   --env FOUND_SCRIPT=resetToDefaultTls.sc \
   --rm -it \
   $(docker inspect -f '{{ .Config.Image }}' frc-directors-director) \
   /elastic_cloud_apps/shell/run-shell.sh
   ```
2. On all of the proxy hosts:
   ```sh
   docker rm -f frc-proxies-proxyv2
   ```
