My family has been on the Internet since 1998 or so, but I didn't really think much about Internet security at first. Oh sure, I made sure our eMachines desktop (and its 433Mhz Celeron CPU) was always running the latest Internet Explorer version and I tried not to use the same password for everything. But I didn't give much thought to where my Web traffic was going or what path it took from our computer to the Web server and back. I was dimly aware that e-mail, as one of my teachers put it, was in those days "about as private as sticking your head out the window and yelling." And I didn't do much with that knowledge.
That sort of attitude was dangerous then, and the increasing sophistication of readily available hacking tools makes it even more dangerous now. Luckily, the state of Internet security has also gotten better—in this article, the first in a five-part series covering online security, we're going to talk a bit about keeping yourself (and your business) safe on the Web. Even if you know what lurks in the dark corners of the Internet, chances are you someone you know doesn't. So consider this guide and its follow-ups as a handy crash course for those unschooled in the nuances of online security. Security aficionados should check out later entries in the series for more advanced information
