can you maybe link some ressources on how the protocol used can be detected? i did not know about this and would like to read into it some more :)
Look up NBAR for the basic idea. Each vendor has their own 'secret sauce' implementation, Palo Alto only needs 9 bytes of payload for disambiguation, iirc.
thank you! so it is basically looking at identifiable patterns in the packet flow and matching them to protocols. i also found this paper about traffic identification interesting.
Time to up the spoofing game. Maybe some AI-generated traffic to throw off the packet analytics.
