So what is the solution for a public network operator. I attended a presentation last week where a Checkpoint reseller suggested the client needed to buy eight Checkpoint firewalls to protect a single web server. I was impressed, what about the undercoating and scotchguard fabric protector. Is it time to fall back in punt? How would you architect a backbone if you could do it over? Enable BGP authentication Enable NTP authentication (use more than GPS as a source) Enable OSPF/ISIS authentication Use TL1 on the Aux port for network management Ip route null0 packets from outside containing internal-only backbone addresses. Is the complexity of SSH code worth the protection? Or is it better never to access your routers through VTY ports, and always use an reverse-terminal server to the console from an out-of-band management LAN?
