So how about High Availability ? I have recently setup two slackware linux based firewalls with some nice iptables setup with lids (linux intrusion detection system) which locks down the kernel and makes the file system not writable :) Each firewall I setup High Availability (www.linux-ha.org) so if one machine is down (non-responsive) the other one will take over. Also to help in the prevention of DOS attacks --- what about syn cookies ? Michael. On Thu, 20 Nov 2003 12:10:27 -0500 Shawn McMahon <smcmahon () eiv com> wrote:

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.The problem with this, as I'm sure you know (but it bears repeating for the peanut gallery) is that it turns any DoS on your firewall into an instant security hole. That escalates the severity of DoS bugs on the firewall, which greatly increases the need to upgrade it when they're found, which can increase your downtime.
