Assessing Bluetooth Security Issues

Note

Files are sent back and forth with your Treo using the Bluetooth General Object Exchange Profile, which is based on the Object Exchange (OBEX) communications protocol. OBEX is designed to allow the exchange of binary objects between devices and is supported in Palm devices as far back as the Palm III for sharing PIM data. OBEX is typically associated with infrared communication but is also used regularly now for transferring files and data via Bluetooth.


There have been some concerns in the mobile community about Bluetooth security as more devices ship with support for Bluetooth. The concerns primarily have to do with Bluetooth being capable of opening a notebook PC, handheld, or mobile phone to wireless attacks. Part of the problem is that some users don't realize that, by enabling Bluetooth on their devices, they might be opening a gateway for unwanted communications, much like accessing the Internet without a firewall. Another part of the problem concerns a few faulty Bluetooth implementations that exposed several models of mobile phones to attack.
