During the past few weeks I gave several talks about IPv6 security, at different venues. The first venue was LACNIC XV, held in Cancun (Mexico), where I gave a tutorial about IPv6 security, and a presentation about Neighbor Discovery vulnerabilities (the latter in the context of LACSEC 2011).
They were followed by two presentations in Arequipa (Peru): one about IPv6 security during CONATEL 2011, and one about Neighbor Discovery vulnerabilities during the Cisco Academy Conference 2011.
Finally, I travelled to London (UK), for a workshop about IPv6 transition organized by CPNI.
The slides used for these presentations can be found here.
