ASP.NET SECURITY

1. Windows Authentication

2.Anonymous Authentication

3.Passport Authentication

4.Forms Authentication

Windows Authentication:-

In this mode of authentication we authenticate user at IIS level which means user must provide credentials to IIS . Windows Authentication process will be involved with following steps:

1>Client makes a request for secured web page.

2>IIS will stop the user and check for user credentials. When not found it displays a "login window" to client.

3>User enters the credentials which is provided by admin of server and submits the login window to IIS.

4>IIS takes user name,password from login window and checks the same in configured windows accounts. After checking it creates and provide identity to client along with this identity to user is sent to ASP.Net secured page and then ASP.Net redirects the secured page to user like this we can restrict our pages to only windows authenticated users hence windows authentication.
