Cisco: Taking a LeapBy Baselinemag | Posted 2003-11-01 Email Print

The networking giant has come up with its own version of a wireless security standard. It works well for some. Others see limitations.
Market leader Cisco Systems says it has an answer for network managers trying to sort out Wi-Fi security. Known as the Lightweight Extensible Authentication Protocol (LEAP), it's Cisco's implementation of an emerging wireless-network security standard that plugs holes in the authentication and encryption standard built into most existing corporate facilities.
There's just one problem: Even though they agree it is a big improvement, many users of Cisco's wireless-network access points are avoiding LEAP. Some Cisco customers, such as Carolyn Coulter, systems officer at the Boston Public Library, see LEAP as a proprietary system that doesn't fit on a network open to a variety of devices, from standard PC laptops to Macs and handheld devices.
In Boston's 27 librarieswhere 100 Cisco wireless access points have been deployed over the last year for patron useCoulter can't be sure that all visitors will have Cisco-compatible gear. So she plans to use a gatewayBluesocket's WG-2100to authenticate users on the library's network and possibly to encrypt wireless traffic.
Other Cisco customers are bypassing both LEAP and other gateways altogether. The Hotel Valencia in San Jose, Calif., for example, provides unlimited access to its wireless network but restricts what guests can do. The upscale, 213-room hotel, which has deployed four Cisco wireless access points covering the property's public areas, doesn't authenticate users, nor does it encrypt wireless traffic. But it limits users to Internet access, and walls off its wireless network from its wired one, according to Information Technology Director David Besser.
At CareGroup Healthcare Systems' six hospitals, where doctors can't afford to have the network fail, laptops and a Cisco wireless network are used to access patient records. Cisco LEAP security works in the hospital environment, says CIO John Halamka, because the type of clients accessing the network there can be strictly limited to those with LEAP-compliant cards and software. "The hospital is a more-controlled environment versus academia," says Halamka, who is also CIO at the Harvard Medical School. "Here we can really clamp down and be rigorous about what kinds of wireless devices we allow and what we don't allow."
