Not long ago, when wireless networking was new and rare, security was an afterthought. The reason? The scarcity of 802.11b cards acted as a form of back-handed security. If no one had an 802.11b card, outsiders couldn’t very well scan your setup, right? Now, however, that’s changed. Wireless gear is readily available–and cheap–so that almost anyone with a PC can afford a Wi-Fi network card, making security more vital.
