Rule n° 209 - Integrity control of third party resources is present and valid.

It is possible to verify that the third-party resources (files scripts, style sheets ...) have not been modified to insert malicious code. For this, the server will continuously check the sent files are the correct files. This rule encourages the implementation of this security measure.
