Research on AS path betweenness based filtering policy against BGP prefix hijacking

BGP prefix hijacking is a sort of security threaten of the Internet. The current effort on hijacking defense is to deploy filters for hijacking route on the edge of the Internet. In order to reduce the deployment cost of defense filter, we proposed an AS path betweenness based filter policy. By simulating a large amount of prefix hijacking experiments, we found that deploying defense filters on the core of the Internet is an effective and efficient way to gain high resilience of the network.
