In order to secure web traffic, SSL (Secure Socket Layer) is generally used as a first line encryption defense (you know, it makes the little padlock icon on your browser). SSL is also known as TLS (Transport Layer Security) which is kind of its newer name. Normally you access a site by navigating your browser to some place like: http://www.devtoolshed.com

By default, application pools (including the default app pool) in Internet Information Services (IIS) 7 use the "Network Service" account as their security identity. For most cases, this default identity should work well for most ASP.NET applications. But in some cases, you may need to configure custom security rules or you may want to isolate your process under its own lower privileged account. In addition, there may be cases where you need to find out what account your ASP.NET process is currently running under in IIS.
