Definition Edit

An Internet border router is a router that is usually deployed in front of the organization's main firewalls and performs some basic checks on network activity, such as ingress and egress filtering, that may be helpful in stopping some Internet-based worms from reaching the organization's firewall.

Overview Edit

Although the firewall should also block such worms, having the Internet border routers do so can take some load off the firewall. During a major worm incident, organizations might need to reconfigure some of their Internet border routers to block incoming worm activity so that the firewalls do not become overloaded.
