We will start with a brief overview of known vulnerabilities in the Border Gateway Protocol (BGP). These vulnerabilities, when exploited by malicious attackers, can severely disrupt the Internet routing functions. We will focus specifically on the impact of BGP peering session attacks. These attacks are known to drive routes into route flap damping (RFD) suppression states and thus cause prolonged isolations between autonomous systems and destinations. We present a detailed study of the impact of BGP peering session attacks and the resulting exploitation of RFD that cause network-wide routing disruptions. Analytical results provide insights into the nature of the problem and impact of the attacks. Detailed packet level simulation results complement the analytical results and provide many additional insights. If time permits, we will also discuss a modeling approach for evaluating the cost vs. benefit tradeoffs associated with implementing countermeasures.
