Enabling TLS/SSL for Cloudera Data Science Workbench

Cloudera Data Science Workbench uses HTTP and WebSockets (WS) to support interactive connections to the Cloudera Data Science Workbench web application. However, these connections are not secure by default. This topic describes how you can use TLS/SSL to enforce secure encrypted connections, using HTTPS and WSS (WebSockets over TLS), to the Cloudera Data Science Workbench web application.

Starting with version 1.6, Cloudera Data Science Workbench defaults to using TLS 1.2. The default cipher suites have also been upgraded to Mozilla's Modern cipher suites.

Cloudera Data Science Workbench can be configured to use a TLS termination proxy to handle incoming connection requests. The termination proxy server will decrypt incoming connection requests and forward them to the Cloudera Data Science Workbench web application. A TLS termination proxy can be internal or external.
