Securing Wireless Data Transmission

You can connect a handheld device to the corporate network using wired or wireless connections. For a few applications, you can equip your device with an Ethernet card and use a permanent connection to a LAN, but in the majority of cases, your device connects to the network wirelessly.

Many devices connect to the LAN using 802.11b protocols. Researchers at the University of California, Berkeley have demonstrated that the static shared-key Wired Equivalent Privacy (WEP) algorithm used to secure wireless LAN connectivity is easily defeated. Researchers are working on WEP2, which will plug the gaps in 802.11 security, and commercial companies have released interim solutions, such as RSA Security (http://www.rsasecurity.com ...
