6Guard (IPv6 attack detector)

Description

6Guard is an IPv6 attack detector aiming at link-local level security threats, including most attacks initiated by the THC-IPv6 suit and the advanced host discovery methods used by Nmap. It can help the network administrators detect the link-local IPv6 attacks in the early stage.

6Guard is sponsored by Google Summer of Code 2012 and supported by The Honeynet Project organization. The project page is at Project 9 - IPv6 attack detector (Xu).

Here is an example of the attacking alert message provided by 6Guard.
