David Fournier, senior information security analyst for a large New England grocery chain, is charged with securing a wireless network utilized by several thousand devices.When those clients range from wireless PCs to handheld scanning devices and transmit everything from mission-critical inventory data to day-to-day Web traffic, keeping business needs aligned with the wireless security policy isn't easy.
"It's a constant battle between availability and secu-rity," Fournier says."It's about providing the availability and convenience of a wireless network, but in a secure manner."
Fournier says that in addition to an authentication system based on Cisco Systems' proprietary LEAP protocol, his company has a policy that relies on virtual LANs and SSIDs to segment guest wireless users.
