A bit late but:

Network traffic and any local software like McAfee HBSS installation. That though depends on what is configured. Certain traffic doesn't have to be caught on the network level, it can be caught before it even leaves your client/server. LMAO, if you were trying to run this from a server....wow, you deserve to get fired.

EDIT:

On another note; Ability to use USB on a client is a huge IA risk factor. You must work for a company which doesn't give a crap about IA. USB allowance should be justified on a case by case basis.
