Learn about monitoring critical Internet infrastructure through a conference talk that examines BGP origin hijack detection for root DNS prefixes. Discover how researchers began using Code BGP in January 2023 to monitor root DNS servers, which serve as authoritative name servers for the DNS root zone and represent critical Internet infrastructure at the top of the global DNS hierarchy. Explore the reasoning behind monitoring these heavily anycasted prefixes, where BGP anomalies might go unnoticed due to anycast's minimal impact on the data plane. Gain insights into BGP's inherent vulnerabilities and understand the methodology for detecting potential security threats to essential Internet infrastructure. Review detailed findings from 2.5 years of monitoring, including specific BGP anomaly events detected involving root DNS prefixes and estimations of their impact on the data plane. Understand the technical challenges of protecting critical Internet infrastructure and learn about practical approaches to network security monitoring from Lefteris Manassakis, a Technical Leader at Cisco ThousandEyes and co-founder of Code BGP.
