The general use of firewalling that I think has some sensibility is
when you have a network administrator who is administratively separate
from the people in the network, and in which the network administrator
trusts the people in his network not to be malicious, but he doesn't
trust them to be good security administrators.

In that case, he can block ports which are commonly used to violate
badly configured machines behind his network.  This doesn't help at
all against the person behind the firewall who just runs services on a
different port, or sets up firewalls, and the like; hence the
qualification that he must still trust them not to be malicious.

"Firewalling" on a single host is mostly a way to cheaply fix a bunch
of problems rather than fixing them one at a time.  It's not
inherently necessary if the other things don't already have gobs of

In any case, none of this is anywhere near the most important
obstacles keeping the Hurd from Prime Time.  Way, way, way down on the

I think that depends on who the "you" is that you are talking to, and
it's misguided to think the answer must be the same for everyone.
