Block Facebook App

We are using a Palo Alto Firewall and have facebook blocked on the browser, but the mobile app still works on Android and iPhone. What is the catch all way to block the facebook app?

@newfrenchbakery my guess would be that you are not decrypting traffic coming from mobile devices, which means that application identification is going to be poor. A quick search shows the addresses listed below.

Please keep in mind that while block all the IP ranges that facebook owns would limit the ability to access facebook, it may also have unintended consequences. If you were to implement anything I would first build out a test rule that targets your computers IP or user-id to verify that this is actually going to function as you expect.

Facebook owns:

66.220.144.0-66.220.159.225

69.63.176.0-69.63.191.255

204.15.20.0-04.15.23.255
