Understanding the Layers of Wireless LAN Security

While a wireless LAN can be installed by simply plugging an access point into an Ethernet port, an enterprise wireless LAN deployment requires a more thought-out plan that incorporates advanced security and management technologies.

Security-conscious enterprises are fortifying their wireless LANs with a layered approach to security that mirrors the security of wired networks. This layered approach to security addresses all network components by locking down the wireless LAN’s perimeter, controlling access to the wireless LAN, protecting the data, and monitoring network traffic.

Wi-Fi Developers Pursue Plans for More Services
(eWeek - March 24, 2003)
Major carriers disagree on the commercial viability of public WLAN hot spots and, as such, are
taking very different approaches to the market. While companies such as Nextel Communications Inc.
and Sprint PCS Group are taking a wait-and-see approach to 802.11b, or Wi-Fi, others such as Verizon Wireless Inc., AT&T Wireless Services Inc. and Cingular Wireless are moving ahead with new
services. The latter moves are not surprising, considering the rapid rollouts of wireless LAN hot spots. ... read more

Wireless Wise: Staff needs new skills to work with wireless signals & plug security holes
(Network World- March 24, 2003) 
Rolling out wireless LANs requires a new set of operational and network management skills that are in short supply. You'd be wise to familiarize your staff with the technology now so they're ready for future deployments. "It's not a matter of just going out to find thousands of people who have all this wireless experience. They're not there," says Charlie Wehner, a senior analyst at Cerner, a healthcare software vendor in Kansas City, Mo. "You almost have to bring your network administrators up to speed on this."  ... read more

WPA Security Enhancements
(802.11 Planet - March 20, 2003)
Wired Equivalent Privacy (WEP) doesn't provide enough security for most enterprise wireless LAN applications. Because of static key usage, it's fairly easy to crack WEP with off-the-shelf tools. This motivates IT managers to use stronger dynamic forms of WEP. The problem to date, however, is that these enhanced security mechanisms are proprietary, making it difficult to support multi-vendor client devices. The 802.11i standard will eventually solve the issues, but it's not clear when the 802.11 Working Group will ratify the 802.11i standard. As a result, the Wi-Fi Alliance has taken a bold step forward to expedite the availability of effective standardized wireless LAN security by defining Wi-Fi Protected Access (WPA) while promoting interoperability.  ... read more
