Youtube
The Bandwidth Killer
to be honest i learn a lot from youtube whether cisco configuration or paloalto or even other things
but during work hour many user using youtube to hear songs, watch a movie trailer which kill the internet bandwidth so i explain earlier how to block facebook using APP-ID
but Youtube APP-ID is little diffrent cause it depend in google-base which will forbid google website too
so URL Category may save the Day
this remind me of Microsoft TMG

So first let create a URL Category
Go to Objects – Custom objects – URL Category – add new
(Youtube)
Add URL (www.youtube.com) Also you can add more (*.youtube.com)

now we create a security policy
Go to Policies – Security – add new (Stop Youtube)

Select the Source Zone (inside) and the Source Address (My Laptop IP  Address)

Select the user aysar.mohamed (Me)
Select the Destination as my Outside Interface
Select any in Application tab
well here we go
in Service/URL Category we select the (Youtube) Category that we create earlier
put the Action to deny
now when i try to open Youtube i got the deny messgae ;D
As you can see from the log i got the (Reset-both ) Action in rule of Stop youtube

;D
