What an amazing world we live in! Almost anything you can imaginecan be researched, compared, admired, studied, and in many cases,bought, with the click of a mouse. The Internet has changed ourlives, putting a world of opportunity before us. Unfortunately, ithas also put a world of opportunity into the hands of those whosemotives are less than honorable. A firewall, a piece of software orhardware that erects a barrier between your computer and those whomight like to invade it, is one solution.
