Windows can be protected by any firewall, pix, ipf, ip, iptables, fw-1,
and running on fairly cheap hardware.  And there are a number of free and
cheap personal firewall products out there, of varying degrees of ease of
use and effectiveness.  W2k boasts firewalling with the OS

Yes, the heavier the load<s> the costlier the HW at least to privide the
perimiter defenses, but, there are pretty high bandwidth capable firewall
choices available.

I'm not trying to insult you here, I'm merely trying to understand why
utdallas would pay for security folks if they don't have a decent policy
and the power to enforce it, especially in light of the fact that IT and
security always have been and most likely will continue to be underfunded,
perhaps especially in the .edu environments.  I work in an environment
that deals with a large number of .edu systems, in the k-12 realm as well
as the university level, and I've yet to run into the smallest rural grade
school that is not at least running a pix doing NAT or PAT.  How
effectively is another question all together.

OK, so you're a Ph.D.  Just don't touch anything.
