Abstract

Internet is composed of a set of autonomous systems (AS) managed by an administrative authority The Border Gateway Protocol (BGP) is the exterior routing protocol used to exchange network reachability between the border routers of each autonomous network BGP allows the ASes to apply policies when they select the routes that their traffic will take Policies are based on business relationships and traffic engineering constraints It is currently assumed that the exchanged reachability information is correct In other words, the ASes that originate a network prefix are supposed to be authorized to advertise it It also means that the announced routing information is conformant with the routing policies of the ASes This assumption is not true anymore We review existing proposals aiming to solve internet routing security issues and present our contributions First, we propose a system able to detect and to react to illegitimate advertisements Then, we describe our current work that focuses on the specification of a collaborative framework between ASes aiming at cautiously select routes.
