I really wasn't planning on posting anything until the new year, but this story in the SANS NewsBites prompted me to post this up. NIST has posted a final version of its "Guidelines for the Secure Deployment of IPv6."
This has ramifications in a bunch of checklists that DoD auditors will be looking at. From experience though, I know of many checks in the Application Security and Development checklist where this will have impact. Specifically, you can look at: V-16781, V-6164, V-6165, V-19706, V-19707, V-19708, V-19709, V-16829, and mentioned in V-16822 and V-16836.
