Bluetooth can bite
With an estimated 250 million Bluetooth-enabled devices currently in use, the fact that Bluetooth is about as secure as the proverbial wide-open barn door should be of concern to everyone responsible for the safekeeping of corporate data.
Yes, there is a Bluetooth security spec, but it's an option most manufacturers choose not to enable. Unless the manufacturer states somewhere on the box that security is enabled in its product, you have no way of knowing. It would require much more work on both the manufacturer's and user's part to ensure that the Bluetooth device can share data only with your PC. Indeed, manufacturers often open everything up so it is discoverable by any device, a condition known as "promiscuous mode."
