Useful article on .NET permissions from O'Reilly:

"The .NET security system is a marvelously intricate invention. You can customize the permissions available to an individual assembly or a group of assemblies (such as all code from a particular publisher) on an amazingly granular level. But many developers are a bit hazy on how all of the pieces fit together to generate these permissions. In this article, I'll walk you through the process of calculating permissions by hand. Armed with this knowledge, you can more effectively configure .NET to secure your assemblies."
