In the first part of this series we tried to identify which risks related to network-related threats actually change when IPv6 gets deployed and hence which ones to take care of in a prioritized manner (as opposed to those which one might be tempted to [initially] disregard with a “has been there in IPv4 already and we did not address it then, why now?” stance). Let’s assume we went through this step and, for those most relevant risks we identified, we want to come up with infrastructure level controls first, before tackling controls to be deployed on the host level (as in many organizations the sysowners of “hosts” like servers in datacenters tend to expect “the network/infrastructure guys to provide the 1st layer of defense against threats”, in particular once those originate from an apparent network layer protocol, that is IPv6).

We’ve been involved in some activities in this space recently and I thought it could be a good idea to share a couple of things we’ve discussed & displayed. Furthermore some time ago – in the Is IPv6 more Secure than IPv4? Or Less? post – I announced to come up with (something like) an “IPv6 threats & controls catalogue” at some point… so here we go: in an upcoming series of a few blogposts I will lay out some typical elements of an “Enterprise IPv6 Security Strategy” incl. several technical pieces (and I plan to give a talk on the exact topic at next year’s IPv6 Security Summit).
