Abstract
Border Gateway Protocol (BGP) is the defacto inter-domain routing protocol in the Internet. It was designed without an inherent security mechanism and hence is prone to a number of vulnerabilities which can cause large scale disruption in the Internet. Route leak is one such inter-domain routing security problem which has the potential to cause wide-scale Internet service failure. Route leaks occur when Autonomous systems violate export policies while exporting routes. As BGP security has been an active research area for over a decade now, several security strategies were proposed, some of which either advocated complete replacement of the BGP or addition of new features in BGP, but they failed to achieve global acceptance. Even the most recent effort in this regard, lead by the Secure Inter-Domain Routing (SIDR) working group (WG) of IETF fails to counter all the BGP anomalies, especially route leaks. In this paper we look at the efforts in countering the policy related BGP problems and provide an analytical insights into why they are ineffective. We contend a new direction for future research in managing the broader security issues in the inter-domain routing. In that light, we propose a naive approach for countering the route leak problem by analyzing the information available at hand, such as the RIB of the router. The main purpose of this paper was to position and highlight the autonomous smart analytical approach for tackling policy related BGP security issues.
