I think I am a security guru, and I agree with you 95%.
The major *security* advantage of IPv6 is that it removes 90% of
complexity of IPv4 networks that results from layers of NAT, and then
series of port-forwards through them.
Do you realize that a 30 year old IT "professional" likely has never
been on the Internet? Seriously. They got a home "router" for their
DSL connection in 1997 when they were 17... they have spent their entire
"adult" life behind some kind of IPv4 NAT.
I once spent some time with a few such young people, and I came to
understand that they were profoundly confused about what home "routers"
do--- they assumed that all *routers* everywhere on the Internet do NAT.
After all, *CISCO* routers run the world, and CISCO owns Linksys...
Therefore a 3% security advantage of IPv6 is that it requires that
know-it-all young people and you-can't-teach-me-anything grey beards
have to learn new things and therefore have a better chance that they
will get correct information.
The other 2% is that when you get what appears to be attack from
2607:f0b0:f:3::178 via some internal network (on the wrong side of your
firewall), you have a way better chance of tracing it than if the attack
comes from 10.10.10.178. That contractor PC with outgoing PPTP tunnel
didn't mean to advertise your 10.10.10.0/24 network to my 10.10.10.0/24
network via OSPF, it just "happened".
The above will, I think, be a daily occurance in the world of SmartGrid
for the first 10 years.
