The concepts related to SSL, CAs, and so on, covered in the previous section help us to add a new block to our road map. This new block is labeled Traffic encryption (SSL). In this section, we will be able to finalize the diagram started at the beginning of the chapter; filling in the details for the dotted rectangle in the diagram.
In this final subsection, a mini-project will be used to secure the front-end communication from the HTTP server down to the Application Server. A the end, you should have an IHS listening on a non-conventional port using HTTPS to communicate with browsers; and through the WebSphere Plug-in, use SSL to talk to the Application Server.
