I'll give you a very indirect answer. We have difficulty with that even domestically. There is no mechanism that compels, for example, banks to share information among themselves of threats they may share in common. There's no thing to compel telecommunication carriers, for example, to inform downstream organizations, whether those are banks or governments, of things that may be actually affecting them on an intelligence “sharing” level vis-à-vis cyber. This is a cascading problem that scales up to NATO.
I think the honest answer is no, there isn't a mechanism. There are mechanisms that we are trying to adopt, but there isn't a solution to this problem. That's one of the challenges.
