Ouch. Yeah, there's that part of it too. Policies are probably in place for
that. Being that I'm one of the firewall administrators, tools like firewalk and
nessus help find the holes for me and I don't think twice about using them on my
own network or when testing my network from home. But I wouldn't be doing that
to someone elses network without prior WRITTEN consent and the full knowledge of
higher ups. You would do well to heed Bruce's warning.
