Maybe your network policy states that, but I would prefer for single
point of failure devices to fail open, rather than closed. For us,
network availability is a higher priority than protection is. If the
firewall fails, I don't want the entire network down while we're waiting
for a vendor to fix it. I'd be surprised if most networks aren't that
way.
Now, if it's something really critical *inside* the network that is
protected by a firewall, then you might want it to fail closed, but at
the edge?
