Bluetooth Security

Bluetooth Security
The structure of a Bluetooth network provides plenty of common sense security measures. Authorization has to be approved by all parties before any connection can be made between Bluetooth devices. When not in use, Bluetooth feature on cell phones and most devices can be turned off which protects that equipment entirely.

There are a few potential attack scenarios that befall Bluetooth-enabled devices; they can, however, be prevented by careful use of the Bluetooth device. For example, it's not wise to accept a transfer from an unknown Bluetooth devices. Bluejacking is a common prank played when you receive an empty business card with a fake message in the "name" like "I have broken into your phone memory." The aim is to make your cell phone or device appear as though it is malfunctioning.

Another potential security risk is known as Bluesnarling, or Bluebugging, which can cause a bit more damage. Implementation bugs in some Bluetooth devices allow hackers to remotely access your phone without approval and use the cell phone or devices features. It even allows calls to be made and user information to be changed. .

According to Howstuffworks.com, a third security risk for Bluetooth devices is called Car Whisperer. This software allows hackers to send and receive audio to and from a Bluetooth enabled car stereo, making it possible to eavesdrop on conversations within your car. The best way to combat this - a fairly rare occurrence to begin with - is to make sure you turn off the Bluetooth car kit when not in use.

Cell phone viruses that cripple or affect cell phones in different ways can also be spread through a Bluetooth network. These viruses detect vulnerable devices in a network and perform unauthorized installations in order to keep spreading. This is usually referred to as a Bluetooth Virus.
