Absolutely. This is not something we can do on our own, given the private investments in cybersecurity.
One point I noted when I was in England speaking to the police there about some of the cooperation going on now between financial institutions, for example, is that there has always been a reluctance for financial institutions to cooperate fully. But I think everyone is coming on board in understanding that the simple fact that one institution has been the victim doesn't mean that the hackers haven't utilized a trail through other financial institutions.
The importance of integrating our response to any of these attacks is very great. The Internet or cyberspace really doesn't make a distinction; whether you're privately owned or publicly owned, if there's a path, it will find a way.
