Tim - 
Thanks for putting your concern out on the list.
If after reviewing http://tools.ietf.org/html/draft-ietf-6man-node-req-bis-08
you are not happy with the security references, then as I said at the mic, this
is something better addressed in either v6ops or 6man, since they own the
implementation/maintenance of the protocol. This draft is not the correct
location to fix any perceived lack of clarity around IPv6 security
considerations, because it is not implementing anything new.
That said, the draft is certainly open to other suggested references to address
your concern, including additional text within the security considerations
section that reference useful info in other drafts/standards. If there are
additional informative references beyond what is currently found in the draft (
http://tools.ietf.org/html/draft-george-ipv6-required-01#page-6 ) I'm glad to
have them.

Thanks, 
Wes George

Subject: [Int-area] draft-george-ipv6-required-01.txt --- what about IPsec ?



The Security Considerations section in draft-george-ipv6-required-01
says:

  5.  Security Considerations
  
     There are no direct security considerations generated by this
     document, but existing documented security considerations for
     implementing IPv6 will apply.


At a minimum, your Security Considerations should contain a pointer to where
those existing security considerations for implementing IPv6 are fully
documented.


Reading the above Security Considerations section reminded me that I once heard
a rumor that IPsec is required in IPv6.

It would be nice to know if that rumor is (still) true.  

I spent about 10 minutes before the int-area meeting started trying to figure
out what I should read to know if IPsec is required in IPv6.  I didn't find
anything that was completely clear about that.

The Security Considerations section of RFC 2460 says just this one
sentence: "The security features of IPv6 are described in the Security
Architecture for the Internet Protocol [RFC-2401]."  That seems to be less than
the full story.

RFC 2401 is obsoleted by RFC 4301. RFC 2401 and RFC 4301 both contain this
identical sentence: "This section defines Security Association management
requirements for all IPv6 implementations and for those
IPv4 implementations that implement AH, ESP, or both AH and ESP."
This seems to imply IPsec is required in all implementations of IPv6.

But I observe there is almost no use of IPsec today, on IPv4 or IPv6,
other than for VPN tunnels.   I've seen plenty of use of IPv6, but
don't believe I've ever seen IPsec over IPv6.

I fear "IPsec required for IPv6" would slow deployment of IPv6.  More widespread
implementation of IPv6 even if IPsec is not included would be a good thing.
