Ask any experienced network > admin. There will always be users who bring into a firewalled network > a laptop that was, for example, infected at home. Part of the problem here is network design. For example, if when laptops are brought in they were only allowed to connect to a wireless network and that wireless network was on the far side of the firewall (perhaps slightly more access than from the internet but still majorly firewalled) and treated as untrusted systems which they in fact are, then it would not be such an issue. There is no rule that says you can't have internal firewalls to separate untrusted from trusted systems. But you have to design your network around this idea for it to work. Geo.
