Security Issue of BGP in complex Peering and Transit Networks

Abstract: Border Gateway Protocol (BGP) is a critical routing protocol of the internet, used to exchange routing information between autonomous systems (ASes). BGP is highly vulnerable to many attacks that can cause routing disturbance on the internet. This paper describes BGP attacks, misconfigurations, causes of misconfigurations, impact of these attacks and misconfigurations in BGP and counter measures. Also we analyze new security architectures for BGP, comparison of these security protocols and their deployment issues. At the end we propose new security solution that is Defensive Routing Policy (DRP) to prevent BGP from malicious attacks and misconfigurations. DRP is operationally deployable and very effective to solve BGP problems.
