CSRF Protection

A cross-site request forgery (CSRF) is an attack that exploits the trust that a site has in a user's browser to transmit unauthorized commands. FortiAppSec Cloud uses a dedicated, per user token to track access to protected pages. To protect back-end servers from CSRF attacks, you create two lists of items, a list of web pages to protect against CSRF attacks, and a corresponding list of the URLs found in the requests that the pages generate.

To configure CSRF Protection, you must have already enabled this module in Add Modules. See Add and Remove Modules.

1. Click +Create Page List Table.
2. Configure these settings.
