Jones Seminar: Analyzing the Global Internet

Doug Madory, Director of Internet Analysis, Dyn Research

Friday, September 18, 2015, 3:30–4:30pm

Spanos Auditorium, Cummings Hall

Border Gateway Protocol (BGP) governs how packets are directed across the global Internet. However despite its paramount importance to Internet communications, the protocol suffers from inherent security weaknesses that aren’t simply theoretical. Despite efforts to develop security fixes to BGP, adoption of these mechanisms remains limited and the problems continue unabated. This talk includes real-world examples of routing-based Internet infrastructure attacks and manipulations. Separately, the same data and analytics used to understand these Internet routing issues have also yielded insights into major geopolitical developments in recent years in places such as Iraq, North Korea, and Cuba. The Internet doesn’t exist in a vacuum and its environs shape its development. As a result, real-time measurement of the Internet itself can be often used as a source of understanding geopolitical events.
