7. Questions?

Can a CSRF attack be prevented by SSL?

Moreover, using SSL does not prevent a CSRF attack, because the malicious site can send an “https://” request. Typically, CSRF attacks are possible against web sites that use cookies for authentication, because browsers send all relevant cookies to the destination web site. However, CSRF attacks are not limited to exploiting cookies.

Which is an example of a CSRF attack?

Cross-Site Request Forgery (CSRF) is an attack where a malicious site sends a request to a vulnerable site where the user is currently logged in. Here is an example of a CSRF attack: A user logs into www.example.com using forms authentication. The server authenticates the user. The response from the server includes an authentication cookie.

How to prevent CSRF attacks in ASP.NET MVC?

To help prevent CSRF attacks, ASP.NET MVC uses anti-forgery tokens, also called request verification tokens. The client requests an HTML page that contains a form. The server includes two tokens in the response. When the client submits the form, it must send both tokens back to the server.

How does cross-site request forgery ( CSRF ) attack work?

A CSRF attack works because browser requests automatically include all cookies including session cookies.
