PUBLIC MARKS with tag "cross-site scripting"

Instead of blindly trusting everything that a server delivers, CSP defines the Content-Security-Policy HTTP header that allows you to create a whitelist of sources of trusted content, and instructs the browser to only execute or render resources from those sources. Even if an attacker can find a hole through which to inject script, the script won’t match the whitelist, and therefore won’t be executed.

This class adds CSRF protection to existing PHP applications that make use of PHP's session support for authentication. If you are writing an application from scratch you shouldn't use this; it's designed to protect legacy apps that were not built with CSRF in mind.

The sfCSRFPlugin plugin provides protection against Cross Site Request Forgeries.
