"Unveiling the Risks of Routing Protocols"

Routing protocols are essential to the functioning of the Internet and the services that rely on them. However, many of these protocols were created without security in mind. Initially, the Border Gateway Protocol (BGP) did not account for the possibility of peer-to-peer attacks. Origin and path validation in BGP has been the subject of considerable effort over the past decades, but disregarding the security of BGP implementations, especially message parsing, has led to multiple vulnerabilities that could be exploited for Denial-of-Service (DoS) attacks. There is a tendency to disregard security auditing due to the misconception that these types of vulnerabilities are less severe than origin and path validation issues. This article continues to discuss the creation of vulnerabilities by the neglect of routing protocol security.
