While IPv6 security is relatively well known in European Universities, most enterprises and service providers had little exposure to it. This is becoming really worrying because Microsoft Vista, 2008 includes IPv6 and IPv6 is even the preferred communication protocol. While this is probably a good thing, the transition mechanisms (notably the tunneling) can lead to risk exposure... The IPv4-address exhaustion is for 2010, this means that the migration to IPv6 is happening and that it is urgent to expose the security community to IPv6 with the latest news (like secure neighbor discovery which has been designed to secure the ARP-like function with cryptographically generated addresses). The session also cover the threats linked to the dual-stack approach and the use of carrrier grade NAT.
