Important Palo Alto Networks URL Filtering Service AnnouncementOctober 11, 2017The Palo Alto Networks Support Team circulated the update below last night relating to the Palo Alto Networks URL Filtering service:A new category has been created for your Palo Alto Networks URL Filtering service.  This newly established category, "command-and-control," previously fell within the malware category in the service.  We created this standalone command-and-control category to provide you with more targeted visibility into threats.Required ActionAs a best practice, we strongly urge you to take action as soon as possible by setting the policy action for this new command-and-control category to BLOCK for each security profile.Background: On September 12, 2017, the command-and-control category was released to your Palo Alto Networks Firewall.  This meant that you could visibly see and update profiles for the new command-and-control category on your firewall.  However, the firewall has not yet categorized any URLs as command-and-control.  This delay is to allow you time to properly update profiles for this new category. It is important to note that if you do not set the new command-and-control category to BLOCK prior to URLs and domains being categorized as command-and-control by the firewall, any endpoints attempting to connect to command-and-control categorized URLs will be allowed by default.An exact date for enabling the categorization functionality has not yet been determined, but will be very soon.  The rollout is likely to be phased across our geographically dispersed clouds delivering the service.  We will provide updates on the exact timeline for the launch of the category functionality in the following FAQ on our Live Community.  In the meantime, please take immediate action to set the policy to block for each security profile.For more information and background on this URL Filtering update, please contact a Herjavec Group Security Specialist or visit the Palo Alto Networks  FAQ in their  Live Community.Herjavec Group circulates Palo Alto Networks Security Advisories as this notification warrants attention and may have significance to your Enterprise network environment.
