Is it possible to only access encrypted removable storage?

I just tried to configure device control with the following:

Removable storage: Blocked
Encrypted storage: Allowed

However this will block all removable storage devices including (bitlocker) encrypted devices.

Is it in any way possible to use device control to only allow encrypted removable storage devices and block all non-encrypted ones?

  • Arno, I think the Blocks are applied first, and then the Allows, and that there's no logic operation possible.  You can allow Exceptions though, and that might solve your problem.

  • The exception is does indeed seem to work but is not the right solution. This exception is placed on the device and says that device X can connect regardless of the policy.
    Problem with that is, that device X can still be used after first formatting it and using it unencrypted after that.
