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

6Guard supported by The Honeynet Project organization is founded by Weilin Xu in Google Summer of Code 2012 and improved by Jianjun Chen in Google Summer of Code 2013.

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