AirMagnet today introduced its BlueSweep software, designed to identify nearby devices with Bluetooth wireless technology and alert users to potential Bluetooth security risks. The AirMagnet software identifies and tracks devices up to 300 feet away and lets users know what their own Bluetooth devices are doing.

"While a number of security vulnerabilities in Bluetooth have been identified, Bluetooth security can be managed if one just has the right information," said Craig Mathias, a principal with the wireless and mobile advisory firm Farpoint Group in Ashland, Mass. "AirMagnet has generously developed a free software tool that Bluetooth users should find helpful in determining how secure their devices really are."

BlueSweep gives users a complete picture of nearby Bluetooth activity, including interconnections between Bluetooth devices and all services on those devices. The AirMagnet software also identifies the make and manufacturer of Bluetooth devices within range. This lets users perform real-time audits of Bluetooth activity and potential vulnerabilities. The software also stores activity history for offline analysis.

Bluetooth applications typically require a security code to authenticate communications among devices, similar to the WEP encryption key used by Wi-Fi users. If the code is not used or is compromised, unauthorized access to Bluetooth devices like cell phones, laptops or even onboard automobile computers is possible.
