Argus: An accurate and agile system to detecting IP prefix hijacking

The de facto inter-domain routing protocol, Border Gateway Protocol (BGP), plays a critical role in the Internet routing reliability. Invalid routes generated by mis-configurations or malicious attacks will devastate the Internet routing system. In the near future, deploying a secure BGP in the Internet to completely prevent hijacking is impossible. As a result, lots of hijacking detection systems have emerged. However, they have more or less weaknesses such as long detection delay, high false alarm rate or deploy hardness. This paper proposes Argus, an agile system to fast and accurate detect prefix hijacking. Argus already keeps on running in the Internet for two months and identified several possible hijackings. Initial results show that it usually discovers a hijacking in less than ten seconds, and can significantly decrease the false alarm rate.
