What are the Different Authentication Methods(Using Windows Authentication) which are provided by IIS ?

 Posted by Chvrsri on 7/14/2011 | Category: IIS Interview questions | Views: 4590 | Points: 40

Generally IIS provides four different kinds of Authentication Methods they are :

Anonymous Method

If we select this authentication, IIS doesn't perform any authentication so that any one can access the application.

Basic Method

If we select this method, the user who access the application should provide windows username and password to access the application. Although this is sent through a network by transmitting direct text so it it very insecure.

Digest Method

This method is almost equal to Basic method but the difference is the password is hashed before it is transmitted through out a network.

Windows Integrated Method

In this the application uses the Kerberos protocol to validate(Authenticate) the user. This uses a Secret key cryptography which provides strign authentication for Client/Server applications.
