Defeating NIDS evasion in Mobile IPv6 networks

The diffusion of mobile devices and technologies supporting transparent network mobility can have detrimental effects on network security. We describe how an attacker can lever-age mobility in IPv6 networks to perpetrate known attacks while evading detection by state-of-the-art Network Intrusion Detection Systems (NIDSs). We then propose a new defense strategy based on the exchange of state information among distributed NIDSs. We demonstrate the effectiveness of the proposed solution through a prototype implementation, evaluated experimentally in a Mobile IPv6 network.
