Policy Management - Unknown Traffic Operational Guide


Security rules should always enforce the security policy by matching on the application traversing the firewall instead of just destination TCP/UDP ports. Palo Alto Networks next-generation firewalls have a database of more than 2000 applications used to classify traffic. However, it may happen that specific traffic is not identified and will be classified as unknown.


This process defines sound practices, technical guidelines, and generic processes and procedures that should fit any organization to safely handle the traffic whose underlying application could not be identified by the firewall.
