There is the running joke that I've heard at a few conferences. It basically outlines that the only way to completely secure a computer is to turn it off. Unfortunately, that is basically true. However, a lot of time and effort goes into making systems as secure as possible. Security isn't about keeping things from happening, but it is about reducing the probability that something happens. This week, we started to touch on items relating to security. Any time you make data available over the web, there are security concerns to contend with. This goes even further as you make more and more information available, especially items like credit cards and social security numbers.
Lucky for me, I've been shopping and sharing information on-line for over 10 years. I haven't gotten busted by any identity seeking thieves yet. At least now, more people are aware of it. A couple of years ago my dad's bank called him because his credit card was compromised. They were very proactive about the whole thing, which is reassuring from a consumer standpoint. We still have to be careful going forward, as more and more of our lives get onto the Internet. It isn't just about credit card numbers and social security numbers any more.
People have to be careful what they post about themselves on-line. This is part of being "secure". At my work, we had our Internet do a quick scan on facebook/myspace/etc. for anyone coming in for interviews. This was mostly for laughs, but it could cause havoc for some people.

Another way of securing your computer is to make it a standalone without connections to the web. I remember one office I worked, they used diskless workstations. All interesting ideas, but I don't think we can do our work with either turned off or standalone computer without disk drives.
