Block facebook by URL instead of category. Not doing SSL Decryption

L3 Networker

Hey everyone!  I have a request from one of my other offices to block access to facebook.  The users there are already covered by a policy using a URL Profile that blocks the social networking category.  I also added facebook.com/ and *.facebook.com/ to the block list for that URL profile.  Users are blocked when going to http://www.facebook.com but if they go to https://www.facebook.com they are allowed access and eventually the facebook app takes over.

 

How can I block access to facebook by using URL profiles vs. blocking the application?

 

Thanks!

URL filtering profile should work. Try adding www.facebook.com in block list. Don't calll anything under Service/ Url Categgory tab in the security policy.

 

Hope this helps.

Hi

 

Since SSL encrypts all the http communication, the host header information is invisible to the firewall unless you enable decryption. An alternative method to determin e the URL of a website is to look in the ssl certificate used by the server, and determine the URL from there

 

since facebook uses *.facebook.com , you should be able to add that  (sans the / ) to your URL filtering profile and be able to block the website

 

regards

Tom
