Security threats in Bluetooth technology

Bluetooth allows connecting mobile devices in short range in order to transfer files/videos. It is now a popular means of short range wireless communication. Although Bluetooth is acceptably reliable, there are still some weaknesses in this protocol. Bluetooth is vulnerable to several threats. Since these threats are seldom reported, people are not much aware of them. Existing surveys on Bluetooth security outline only a few threats without much illustration and categorization. In this paper, we have performed a comprehensive survey to identify major security threats in Bluetooth communication and presented them with illustrations. Although Bluetooth device manufacturers are doing their part to keep the technology secure, the users should also be aware of these security threats and take a minimum level of precaution. The objective of this paper is to provide a comprehensive survey of existing threats in Bluetooth technology and suggest probable solutions.
