Operational Solutions

Since Bluetooth devices do not register when they join a network, they are invisible to network administrators. Consequently, it is difficult for administrators to apply traditional physical security measures. However, there are some security approaches that can be applied, including establishing spatial distance and securing the gateway Bluetooth devices that connect remote Bluetooth networks or devices. Establishing spatial distance requires setting the power requirements low enough to prevent a device operating on the organizations premises from having sufficient power to be detected outside physical boundaries. This spatial distance in effect creates a more secure boundary. Currently, Bluetooth devices have a useful range of approximately 30 feet. Organizations that require both high levels of security and low levels of security should maintain a secure perimeter so that on site network users can maintain secure connections in their office premises. Agencies with requirements for high levels of security should also restrict unauthorized personnel from using PDAs, laptops, and other electronic devices within the secure perimeter.
