We don't normally enable Bluetooth on Linux (CentOS 7) installs for

I would like to be able to configure things so Bluetooth can _only_
be used to pair with Wacom tablets (or just HID devices?)
As I never used Bluetooth in anger before, I'm struggling to find
out where to start looking - does anyone know how to do this - or
any pointers for where I should start looking?
Are you asking this from the system or user perspective, from the
system we don't have a configuration where you can restrict the
types of devices that the user can pair, on the other hand there is
nothing stopping the user interface (gnome, kde, etc) to implement
such policy on their bluetooth settings, though be aware targeting a
subset of HID devices may not be possible.
Ideally I would want to limit this at the system level - although I can
not find anything user interface-wise that mentions limiting access
either (although I might be looking in the wrong places?)
My aim is to prevent Bluetooth being used (in any way) to transfer
files/data on/off the workstation
I've found that if I blacklist the bnep, cmtp and rfcomm kernel modules
(just leaving the bluetooth and hidp kernel modules enabled) then the
Wacom tablet still works over Bluetooth
Would this be sufficient to prevent any kind of file transfer over
Bluetooth ?
Thanks
