Prevent Cross-Site Request Forgery (CSRF) using ASP.NET MVC’s AntiForgeryToken() helper

http://blog.stevensanderson.com/2008/09/01/prevent-cross-site-request-forgery-csrf-using-aspnet-mvcs-antiforgerytoken-helper/

Ways to stop CSRF

There are two main ways to block CSRF:

• Check that incoming requests have a Referer header referencing your domain. This will stop requests unwittingly submitted from a third-party domain. However, some people disable their browser’s Refererheader for privacy reasons, and attackers can sometimes spoof that header if the victim has certain versions of Adobe Flash installed. This is a weak solution.
• Put a user-specific token as a hidden field in legitimate forms, and check that the right value was submitted. If, for example, this token is the user’s password, then a third-party can’t forge a valid form post, because they don’t know each user’s password. However, don’t expose the user’s password this way: Instead, it’s better to use some random value (such as a GUID) which you’ve stored in the visitor’s Session collection or into a Cookie
