Clearly there are some things about WikiLeaks... the material is in part very interesting although none of it is a real game-changer. I think if I was an American I'd be rather proud that American diplomats are quite assiduous in the way that they chronicle issues. Of course the impact has been that the whole culture of sharing is going down the tube.

The sort of sweeping parochial espionage and attempts to extract information from all sorts of institutions are well documented, but I think in this context there's a danger of oversimplifying and seeing that sector of cyber as a one-way street.

One of the problem with cyber is that it lends itself to preemptive action. Your assets in cyber-warfare are your opponents' vulnerabilities, therefore in order to quantify your assets you have to be able to ascertain how vulnerable your opponents are and that involves pre-emptive exploration of your opponents' networks. So in that sense it lends itself to some pretty nasty stuff.

There are two types of companies in the world: those that know they've been hacked, and those that don't.

The internet is fracturing into a series of huge country-based intranets, in which governments define, in the name of security, what is legitimate personal and intellectual communication, and what is not.

I think that we're now deep into a struggle for control over the Internet and there are various actors - state, corporate, civic, criminal and military. The great genius of the Internet is its interconnectedness, but this is also what makes it an incredibly difficult problem when things start to go wrong with it and when people exploit for their own purposes.

The Internet has fashioned a new and complicated environment for an age-old dilemma that pits the demands of security against the desire for freedom.
