NSA offers security guidelines for IPv6 migration:

The US National Security Agency (NSA) has published a guidance document for system administrators to help them mitigate potential security issues as their organizations transition to Internet Protocol version 6 (IPv6).

The prosaically named "IPv6 Security Guidance" [PDF] was compiled for admins inside the Department of Defense (DoD), but is likely to prove useful as a quick reference for anyone managing the transition from IPv4 to IPv6, which could turn out to be a more drawn-out experience than was originally anticipated.

"The Department of Defense will incrementally transition from IPv4 to IPv6 over the next few years and many DoD networks will be dual-stacked," NSA Cybersecurity Technical Director Neal Ziring said in a statement accompanying the publication of the document.

"It's important that DoD system admins use this guidance to identify and mitigate potential security issues as they roll out IPv6 support in their networks."

One of the recommendations is pretty basic: education. Successfully securing an IPv6 network requires, at a minimum, a fundamental knowledge of the differences between the IPv4 and IPv6 protocols and how they operate, the NSA says, so all network administrators should receive proper training.

It advises that security methods used in IPv4 networks will largely also be used with IPv6, but with adaptations to address where there are differences.
