The Edge is an interesting site with in depth interviews with smart folks. There’s a long interview with Ross Anderson published recently.
It’s a big retrospective on the changes over thirty years, and there’s enough interesting bits that I’ll only quote one:
The next thing that’s happened is that over the past ten years or so, we’ve begun to realize that as systems became tougher and more difficult to penetrate technically, the bad guys have been turning to the users. The people who use systems tend to have relatively little say in them because they are a dispersed interest. And in the case of modern systems funded by advertising, they’re not even the customer, they’re the product.
Take the time to listen. Ross’s emphasis is a bit lost in the text.
