Folks, It is often argued that IPv4 practices should be forgotten when deploying IPv6, as after all IPv6 is a different protocol! But we think years of IPv4 operational experience should be leveraged as much as possible. So we are publishing IPv6 Security for IPv4 Engineers as a roadmap to IPv6 security that is specifically aimed at IPv4 engineers and operators. Rather than describing IPv6 in an isolated manner, it aims to re-use as much of the existing IPv4 knowledge and experience as possible, by highlighting the security issues that affect both protocols in the same manner, and those that are new or different for the IPv6 protocol suite. Additionally, it discusses the security implications arising from the co-existence of the IPv6 and IPv4 protocols. The document is available at: https://www.internetsociety.org/blog/2019/03/ipv6-security-for-ipv4-engineer... Comments are welcome. And if you think we've missed something or the like, please drop me en email -- the document can always be revised. P.S.: If you haven't taken a look at it (yet), we have also published the "IPv6 Security Frequently Asked Questions (FAQ)" at: https://www.internetsociety.org/blog/2019/02/ipv6-security-faq Thanks!
