Recent years have seen large-scale (though generally single-network) outages caused by misconfiguration, such as route redistribution, and/or software bugs. There is also concern that "properly" architected worm/virus attacks could create networks of hundreds of thousands or millions of devices that could be turned against the router infrastructure.

We will review some vulnerabilties that have been exposed in recent years, primarily relating to router CPU protection; route redistribution; router control/logging systems; the DNS infrastrucutre; and the robustness of interconnection between networks.

The presentation will review some common-knowledge fixes, and will discuss some interesting applications of network architecture and design that can help to mitigate serious vulnerabilities.
