Handy, PDA, Bluetooth
The days when cellular telephones were used only for making calls are long gone. Comprehensive functions such as integrated camera, appointments calendar, games, text messaging and MMS functions, infrared and Bluetooth support and the possibility of surfing the web turn mobile phones into tiny multi-functional devices. Most Personal Digital Assistants (PDAs) also have a Bluetooth function. However, the greater the number of functions on the device, the greater the likelihood of weaknesses. Some implementations of the Bluetooth technology on mobile phones has led to weaknesses in the devices of various manufacturers.
What needs to be done when using Bluetooth
- Bluetooth should only be activated when needed
Activate Bluetooth only when it is needed. Deactivate Bluetooth after use.
- Bluetooth only in secure environment
Use Bluetooth only in secure environments (not in public surrounding) and only if absolutely necessary.
- Enable Bluetooth device visibility only when necessary
- Using the security options
Find out (e.g. from the operating manual or your local dealer) about the security options of your Bluetooth appliance and if possible activate authentication and encryption.
