Secure the Bluetooth Protocol Handler on your virtual appliance host machines to prevent potential attackers from exploiting it.

Binding the Bluetooth protocol to the network stack is unnecessary and can increase the attack surface of the host.


  1. Open the /etc/modprobe.conf.local file in a text editor.
  2. Ensure that the following line appears in this file.

    install bluetooth /bin/true

  3. Save the file and close it.
