Because security is one of the most fundamental aspects in the development and deployment of a Web service, there are a myriad of articles, documentation, and samples of how to make it secure.

Here, I'll share some practical examples on Web service security in .NET, not just abstract theories. These examples provide an easy and fast way to accomplish a rather complex task.
