Using ML to Block BGP Hijacking

Border Gateway Protocol (BGP) has proven to be resilient in the face of failures, attacks, and general maliciousness and incompetence. While there are no deployed mechanisms for automatically remediating BGP announcements that may be malicious, there have been many attempts at fixing this sorry state of affairs. In this article, I will describe some troublesome BGP events and how our tool, Bongo, uses machine learning (ML) and Layer 8 in the IP stack to detect malicious announcements and block traffic that would be diverted.
