Fix Recommendation

Configure OL 9 to disable the Bluetooth adapter when not in use.

Create or modify the "/etc/modprobe.d/bluetooth.conf" file with the following line:

install bluetooth /bin/false
blacklist bluetooth

Reboot the system for the settings to take effect.

Check Contents

Verify that OL 9 disables the ability to load the Bluetooth kernel module with the following command:

$ grep -r bluetooth /etc/modprobe.conf /etc/modprobe.d/*
install bluetooth /bin/false
blacklist bluetooth

If the command does not return any output, or the line is commented out, and use of Bluetooth is not documented with the information system security officer (ISSO) as an operational requirement, this is a finding.
