Cisco IT and World IPv6 Launch – All Systems Go!

For instance, one extension header that you should definitely deny is the Routing Header (RH) Type 0, since this is essentially the same as source routing in IPv4. Fortunately, the RH Type 0 extension header was deprecated by RFC 5095 so it should not be allowed by default on many devices (this has been the default for I…

Cisco Live London 2013: IPv6 Security Lab Recap

Last week my colleagues and I were excited to deliver a 4-hour lab on IPv6 Security at Cisco Live London 2013. The training enabled students to correctly identify, classify, and deter or prevent the nefarious IPv6-specific behaviors. They did so by configuring network threat defense, countermeasures, and controls that were implemented and deployed on infrastructure devices as well as validate their effectiveness. Some of the nefarious behaviors…
