All Internet services depend on two infrastructure components: the Domain Name System and the routing system. Neither has evolved with much security in mind. Both have depended instead on the friendly cooperation of the people who "run the network." These two essential components are increasingly the target of attacks. Even worse, they are frequently subject to misconfigurations (routing more so than DNS), and also heavily affected by distributed denial of service attacks. This talk gives an overview of the DNS and Internet routing, discusses their security vulnerabilities, and explores where we are and where we should be going to improve the situation.
