For a number of years, we’ve certainly been aware of the security vulnerabilities of using 802.11 WEP (wired equivalent privacy) as a method of encrypting data frames traversing 802.11 networks. WPA (Wi-Fi Protected Access) is a much better alternative, but the problem is that WPA is not available in all devices. In addition, it’s sometimes difficult to get WPA working well across client radios and access points made by different manufacturers. As a result, WEP is sometimes our only option for securing wireless LAN connections for the next few years. The common thought is that “at least WEP is better than nothing.” Airtight, however, has recently announced a new tool that helps guard WEP mechanisms against hackers. You might consider this for implementations where only WEP is available, and you need some added protection. Refer to the AirTight press release for more details.
