The new security components in .NET 2.0 can help you greatly reduce the amount of code you need to write in order to make your applications secure. Security is difficult to get right, and it is a good strategy to leverage the code provided by Microsoft and other security vendors. To that end, .NET 2.0 provides numerous additional types that encapsulate functionality already provided in the base Windows OS., as well a new functionality only available in .NET 2.0. The improvements affect public key cryptography, Windows security, remoting, ASP.NET and Code Access Security.
