Hi, I build a system ‘Argus’ to real-timely alert prefix hijackings. Argus monitors the Internet and discovers anomaly BGP updates which caused by prefix hijacking. When Argus discovers a potential prefix hijacking, it will advertise it in a very short time, both in our website (http://argus.csnet1.cs.tsinghua.edu.cn) and the mailing list (argus@csnet1.cs.tsinghua.edu.cn). Argus has been running in the Internet for more than eight months, it usually can discover potential prefix hijackings in ten seconds after the first anomaly BGP update announced. Several hijacking alarms have been confirmed by network operators. For example: http://argus.csnet1.cs.tsinghua.edu.cn/fingerprints/61544/ has been confirmed by the network operators of AS23910 and AS4538, it was a prefix hijacking caused by a mis-configuration of route filter. If you are interest in BGP security, welcome to visit our website and subscribe the mailing list. If you are interest in the system itself, you can find our paper which published in ICNP 2011 (FIST workshop) http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=6089080. Hope Argus will be useful for you. _________________________________ Yang Xiang . about.me/xiangyang Ph.D candidate. Tsinghua University Argus: argus.csnet1.cs.tsinghua.edu.cn
