Practices that can prevent this type of threat include turning off Bluetooth when
your device is not in use and hiding your device from unknown Bluetooth users
by switching off the discovery mode. Firewalls and anti-virus software can also be
installed for enhanced safety. Despite these security challenges, Bluetooth continues
to reign as the industry standard for wireless technology, making it easier than ever to
bring together all our portable electronic devices.
