The issue of cyber-security, cyber-crime, and cyber-malfeasance has an impact on a whole range of issues, not the least of which is civil liberties, political activity, and so on and so forth.

The anonymity issue is a big question. As long as people can disguise cyber attacks and as long as there is a sort of question mark over who is responsible, then the problem will continue to exist. And of course what happens in response to that is that there is a move to try and refashion the Internet so that anonymity is impossible, which of course leads to fears among all sorts of groups - civil rights groups, NGOs, and political parties - that the Internet is going to be used simply as a method of control. So these are very sensitive issues.

When you're researching things that have happened, the clear narrative arc is not there already. This is the problem of writing nonfiction for me - writing nonfiction which is about serious subjects and has serious political and social points to make, yet which is meant to be popular to a degree - what happens when the facts don't fit a convenient narrative arc? I guess that for a lot of nonfiction writers that is a central challenge.

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.

If there is an event for whatever reason, which interferes with the Internet or network communications, are people able to deal with it? It seems like our dependency on these systems is so great that the room for maneuver as it were is very small. So that is problematic.

In 2010, you have roughly 38 billion dollars spent by government on cyber and telecoms security and another 60 billion or so by private corporations. So approximately 100 billion dollars spent on security, mostly on technological solutions, which the corporates are offering governments in particular; it's a very high growth area. So everyone is climbing over each other to get the contracts for government procurement on this. There is undoubtedly an element of this and that's what encourages, in part, the whole idea of locking down the Internet.

The U.S. has the most advanced cyber-weaponry on the planet, and t if you look at the U.S. from the perspective of the Chinese People's Liberation Army, which runs most of its cyber activities, they look at you and they see Google and Facebook - the two largest depositories of personal data in the world - and they see the reach of the National Security Agency, which has huge digital capacity to know what is going on around the world. So the Chinese would see cyber as an un-level playing field, because the U.S. holds all sorts of advantages.
