Clip 1/5 Speaker: Dan Massey · Colorado State University This talk considers security challenges facing the Internet's Domain Name System (DNS). The DNS is one of the most widely used and least secure Internet systems. Viirtually every Internet application relies on the DNS to convert names into IP addresses and the DNS provides a wide range of other critical mappings such as identifying mail servers and locate services. But despite its importance, the original DNS design gave very little thought to security and a variety of misdirection and denial of service attacks are possible. For example, a web browser relies on the DNS to convert www.purdue.edu into an IP address. The DNS supplies the web browser with an IP address (more precisely an "A" resource record set) such as 129.82.100.64 (is this address correct?). If this address is wrong, the browser will be directed to the wrong site. If the DNS fails to return a response, the browser will not be able to load the desired web page. Currently, both the operational and research communities are making considerable efforts to improve DNS security. After nearly a decade of development, the IETF has standardized DNS Security Extensions that add public key authentication into the DNS. The hierarchical structure of the DNS is leveraged to authenticate public keys, keys can be managed offline, and the signatures allow a resolver to authenticate a response. However several open issues remain, including key revocation, support for ...
