UDP 443 becoming more prevelant

L2 Linker

Today I have discovered that the latest Facebook App for Apple IOS is using udp/443 for communication. This behavior seems similar to the Google Quic protocol. I also caught a glimpse of an article referencing the move to a http2/api WWW.


If this is going to be the direction the industry goes, does anyone know how long it takes Palo Alto to signature these applications?


What is the best way your organization has handled these new applications that traditionally are "sanctioned"? Right now on the current APP\Thread DB it is classified as unknown-udp


Just going to throw in with the last few comments; I have udp/443 blocked across every network I manage and nobody has ever noticed it wasn't working, let alone brought up any user experiance issues. 

Same here ... 443/udp blocked outgoing ... 0 problems and 0 users complaining about a bad user experiance
