for me, I use IPCOP as proxy server. I'm too I think I'm over control, but it's is far better than having to fix 100s of computers for virus/spyware/popup problem. I limit the ability to download (doc, exe, zip), do web filter, blacklist. and also let them know that all internet vist will be log, what happen under their login will be their responsibility. There is also a statement to obtain the username request form that they have to sign said those log can be use as part of employee review. Too much abuse/non work related can be use for termination. x-rate stuff is a NO NO. if found, usually will be ground for termination. So, am I over control??? I will do what ever it take to protect my network and prevent bad thing from happening. it's far better than the alternative.
