Wireless Security - The Security Plan for Your Wireless LAN
Torrance Memorial Medical Center has 211 APs throughout its five-building campus that provide 100 percent wireless coverage, Tomcsanyi says. He is able to offer public Wi-Fi because he has the ability to segregate traffic within the network architecture. There’s an open network just for patients and guests, and a secure corporate network that provides the encrypted connections for employees. The two networks stay separate, he says.
According to Cisco, a wireless guest network is an easy way to allow access while eliminating the need for IT personnel to authorize each user. Guest networks use an open security method segregated on a specific SSID (a unique name for each WLAN) that routes traffic to a network that accesses the public Internet only. Tomcsanyi cites increased patient satisfaction levels because of the WLAN access.
While wireless networking has come far in a short time, CIOs now need to realize that the security mechanisms have finally caught up with much of wireless’s blistering hype. "It used to be that you’re going to have to sacrifice some security policies and procedures because you want to have that wireless connectivity," Fessler says. "Now I’m not having to sacrifice that."
