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.

There are governments who are regulating things in different ways and those forms of regulation often don't square up. So you have a real legislative mess, in the meanwhile various bad people are developing all sorts of tools to exploit the Internet for their own gain and the militaries are beginning to develop some extremely frightening offensive capabilities in cyber. Yet all of this is taking place outside of any international agreement or even framework.

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.

It's great that the Internet can enhance and speed up our communications and that computers can do all the things they do. It's fabulous. At the same time, it changes our priorities. For example, before I would always remember people's telephone numbers and now I don't know anyone's number. So what happens if computer systems go down but you still have landlines? Well, I couldn't call anyone because I don't know anyone's number.

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.

The attack on the law firms and attacks like that are industrial espionage, searching for copyrighted materials to lift and so on; it's not quite the same as cyber-warfare. They are regarded as related. The Chinese are trying to steal an economic march on the West, which is a consequence of the fact that we outsourced all of our manufacturing to China in the 1990s.

The criminal justice system - although this applies less to the U.S., where rehabilitation is not seen as a valuable contribution to criminal justice - in Europe where rehab is supposed to be integral, we have no way of rehabilitating skilled hackers. On the contrary what we do is we demonize them and continue to do so after they come out of jail because we restrict their access to computers by law. Crazy world, crazy people.
