Learn about Route Status Transparency (RoST), a novel security solution designed to combat BGP withdrawal suppression attacks and misconfigurations in this 15-minute conference presentation from NSDI '25. Discover how withdrawal suppression has been undermining Internet routing reliability and security for over a decade, creating "BGP zombies" that persist despite being withdrawn. Explore RoST's innovative approach as the first efficient and secure design to verify route withdrawal status while maintaining compatibility with existing BGP infrastructure and security enhancements. Examine simulation results based on the Internet's AS-level topology that demonstrate RoST's effectiveness, and review real-world BGP announcement data analysis showing the solution's practical efficiency in terms of storage, bandwidth, and computational requirements. Gain insights into how this research addresses a critical vulnerability in inter-domain routing that affects global Internet infrastructure stability and security.
