ASP.NET Web Application Security

ASP.NET, in conjunction with Microsoft Internet Information Services (IIS), can authenticate user credentials such as names and passwords using any of the following authentication methods:

• Windows: Basic, digest, or Integrated Windows Authentication (NTLM or Kerberos).

• Forms authentication, in which you create a login page and manage authentication in your application.

• Client Certificate authentication

ASP.NET controls access to site information by comparing authenticated credentials, or representations of them, to NTFS file system permissions or to an XML file that lists authorized users, authorized roles (groups), or authorized HTTP verbs.
