Minor correction (I did say I wasn't sure it was SOX) ... It is PCI that
requires RFC1918 and translation.
For SOX, what is your assessment of (IPv6) internal controls and risk based
on? Has anyone (with the authority to do so) developed and released
guidance? Do we have a repository of "current best practices" to rely on
Interestingly, with SOX, I am curious if lack of IPv6 preparation will play
into the risk assessment as well :).
Current versions of the rest (HIPAA, GLBA, SOX, FIPS, etc.) simply tend to
omit IPv6 completely, and generally require everything not explicitly called
out to be disabled ... thus, no IPv6 on any network that falls under any of
these regulations. We are just starting to see finalized product profiles
and STIGs for IPv6 configuration - without that guidance Defense networks
really couldn't <wink> run IPv6 either.
(In other words (again, generally speaking) - if you run IPv6, your current
C&A (or perhaps your CTO (Certificate To Operate)) is invalid).
