Hi All,

I'm trying to monitor user/program accessing certain website on port 80 or different port. Would below rule work? Tried them but without any success. Perhaps i missed something.

Alert tcp any any -> any 80 (MSG: "user/program accessing Facebook"; content: "www.facebook.com")

Or based on DNS query.

Alert udp any any -> any 53 (MSG: "user/program accessing Facebook"; content: "www.facebook.com")
