Explanation

App-ID, a patented traffic classification system only available in Palo Alto Networks firewalls, determines what an application is irrespective of port, protocol, encryption (SSH or SSL) or any other evasive tactic used by the application. It applies multiple classification mechanisms-- application signatures, application protocol decoding, and heuristics--to your network traffic stream to accurately identify applications. https://docs.paloaltonetworks.com/pan-os/10-2/pan-os-admin/app-id/app-id-overview
