Block Facebook Posting

Hi everyone:


PA Firewall seems to be unable to Block New Facebook posting.
Does anyone have a way to block it?

Hi @RichardChou 

Do have configured SSL decryption, right? And what PAN-OS version do you have installed?

I have configured SSL decryption and I am sure the settings are OK.
Use PA-220 version 9.0 or VM-100 version 10 are not block it.

How does your security policy to block this look like? Did you take the application dependencies into account when you created the block policy?

The pne log entry where facebook-chat is allowed looks special as you configured it to action deny.

Unfortunately it looks like the app facebook-posting needs an update/improvement to cover evrything. I would recommend to open a support case.

Until there will be an improvement, you could also create a custom signature to block these postings.
