Glenn Fleishman’s short ars technica article on wireless security will help the growing number of businesses that offer free WIFI. These networks can be easily secured from common attacks without administrative headaches.
Public WiFi is insecure. But it doesn’t have to be. If you own or manage a venue, like a coffeeshop or restaurant, and provide free and open WiFi, you can help protect your customers without having to provide technical support or waste money. The new reality is that you can offer “open” access without having an open network.
Set you network to WPA with an easy to remember/type password (like wireless). That will stop the Firesheep hacks and make your customers like you even more.
