Chapter 8. ASP.NET Security

This chapter presents guidance and recommendations that will help you build secure ASP.NET Web applications. Much of the guidance and many of the recommendations presented in this chapter also apply to the development of ASP.NET Web services and .NET Remoting objects hosted by ASP.NET.

ASP.NET Security Architecture

ASP.NET works in conjunction with IIS, the .NET Framework, and the underlying security services provided by the operating system, to provide a range of authentication and authorization mechanisms. These are summarized in Figure 8.1 on the next page.
