[c-nsp] Monitor Web Traffic

[Mackinnon, Ian]

Without more info about your network and requirements this is a bit of a
"how long is a piece of string"

Off the top of my head :-
Span your WAN link and analyse the traffic.
Use a web proxy server (eg IIS).
Use netflow to see where your traffic is destined.
Check the dns logs.
Install some monitoring software on the users pc's.
Use NBAR.

All of course subject to your local laws, this may or may not be legal
in your jurisdiction.
