What's the biggest threat to information security at the moment?
Schneier: Crime. Criminals have discovered IT in a big way. We're seeing a huge increase in identity theft and associated financial theft. We're seeing a rise in credit card fraud. We're seeing a rise in blackmail. Years ago, the people breaking into computers were mostly kids participating in the information-age equivalent of spray painting. Today there's a profit motive, as those same hacked computers become launching pads for spam, phishing attacks and Trojans that steal passwords. Right now we're seeing a crime wave against Internet consumers that has the potential to radically change the way people use their computers. When enough average users complain about having money stolen, the government is going to step in and do something. The results are unlikely to be pretty.

Which threats are overly hyped?
Schneier: Cyberterrorism. It's not much of a threat. These attacks are very difficult to execute. The software systems controlling our nation's infrastructure are filled with vulnerabilities, but they're generally not the kinds of vulnerabilities that cause catastrophic disruptions. The systems are designed to limit the damage that occurs from errors and accidents. They have manual overrides. These systems have been proven to work; they've experienced disruptions caused by accident and natural disaster. We've been through blackouts, telephone switch failures and disruptions of air traffic control computers. The results might be annoying, and engineers might spend days or weeks scrambling, but it doesn't spread terror. The effect on the general population has been minimal.
Microsoft has made much of the added security muscle in SP2. Has it measured up to the hype?
Schneier: SP2 is much more hype than substance. It's got some cool things, but I was unimpressed overall. It's a pity, though. They had an opportunity to do more, and I think they could have done more. But even so, this stuff is hard. I think the fact that SP2 was largely superficial speaks to how the poor security choices Microsoft made years ago are deeply embedded inside the operating system.
Is Microsoft taking security more seriously?
Schneier: Microsoft is certainly taking it more seriously than three years ago, when they ignored it completely. But they're still not taking security seriously enough for me. They've made some superficial changes in the way they approach security, but they still treat it more like a PR problem than a technical problem. To me, the problem is economic. Microsoft -- or any other software company -- is not a charity, and we should not expect them to do something that hurts their bottom line. As long as we all are willing to buy insecure software, software companies don't have much incentive to make their products secure. For years I have been advocating software liability as a way of changing that balance. If software companies could get sued for defective products, just as automobile manufacturers are, then they would spend much more money making their products secure.
After the Download.ject attack in June, voices advocating alternatives to Internet Explorer grew louder. Which browser do you use?
Schneier: I think it's foolish to use Internet Explorer. It's filled with security holes, and it's too hard to configure it to have decent security. Basically, it seems to be written in the best interests of Microsoft and not in the best interests of the customer. I have used the Opera browser for years, and I am very happy with it. It's much better designed, and I never have to worry about Explorer-based attacks.
