Bluetooth is a widely used technology that allows devices such as wireless phones, cars and trucks, computers, storage devices, wireless keyboards, and other interactive devices to communicate with each other without cables or wires. It is an electronics "standard," which means that manufacturers that want to include this feature have to incorporate specific requirements into their electronic devices to ensure that the devices can recognize and interact with other devices that use Bluetooth technology.
It is possible to configure Bluetooth technology to be reasonably secure, but if someone can "discover" your Bluetooth device, he or she may be able to send you unsolicited messages or use your Bluetooth service. Worse, an attacker may be able to find a way to access or corrupt your data. Luckily, there are a few steps you can take to prevent this from happening:
Change Bluetooth settings to “Not Discoverable” when not actively pairing. Most hackers will target devices that are within range and discoverable.
Be careful who you pair with and don’t accept any unexpected pairing requests. If you’re trying to pair with your friend’s or your own device, be sure to double check the device’s pairing name.
Avoid pairing devices in public or in crowded locations. In order to pair, you’ll need to make your device discoverable to all potential pairing devices, meaning your device is vulnerable. Make sure to pair devices at home or another secure location.
Disable Bluetooth when you are not using it.
Take advantage of security options. Learn what security options your Bluetooth device offers and take advantage of features like authentication and encryption.
