All deficiencies(described in previuos post ) leave a Bluetooth device vulnerable to security threats. Even though security gaps are being filled every day by the manufacturer and technologist, Following are some of the tips that a normal user can keep in mind and protect himself from an amateur BlueTooth security breacher.
- Keep BlueTooth in the disabled state, enable it only when needed and disable immediately after the intended task is completed.[sintuhack]
- Keep the device in non-discoverable (hidden) mode,
- DO NOT accept any unknown and unexpected request for pairing your device.
- Use non regular patterns as PIN keys while pairing a device. Use those key combinations which are non sequential, non obvious on the keypad.
- Keep a check of all paired devices in the past from time to time and delete any paired device which you are not sure about.
- Register your device at the Manufacturer site and insure that security updates are installed regularly to protect from previously know threat which had been rectified in new models.
- Always enable encryption when establishing Bluetooth connection to your PC.
