Imagine a completely wireless school, an open network in which all students and staff can roam around using laptops or handheld computers to browse the Internet, access files and applications on the school server, and communicate with each other and the world via e-mail. It's a great picture--and at some schools the future is already here. But while wireless provides flexible, portable connectivity, with prices dropping rapidly as the technology becomes a commodity, it also brings attendant security challenges for which there are currently no easy answers. For starters, most traditional network security methods schools are used to employing are incompatible with wireless technology unlike wired networks, signals travel through the air like radio waves with no dearly defined boundaries. Complicating this is the fact that Wired Equivalent Privacy, the original industry standard protocol for securing wireless networks, can be easily cracked by malicious users unless additional safeguards are in place. This article outlines some best practice steps for maintaining wireless network security in schools, protecting administrative data, and dealing with other network security concerns.
