Removable Media Encryption - Not Working.

David Chatterton

We have just installed Sophos SafeGuard Version 8 - We have the Data Exchange module.

Upon testing a couple of Windows 10 x64 machines, I have found I cannot encrypt removable media (testing with a 32GB USB stick).

Sophos Client is installed and is synchronising with the server - the laptop responded fine to internal storage encryption and BitLocker was set up as expected.

I have a policy set and applied for Removable Media Encryption, however when I plug in USB memory, nothing happens. The USB memory is being assigned drive letter D:, but this does not show on the drives tab in SafeGuard.

Windows 7 machines seem to be able to list removable drives under SafeGuard.

Am I doing something wrong?

Thanks.

    Hi David,

    In safeguard we just log fixed drives, removable drives are not reported.

    Have you setup your removable media policy with file encryption and to prompt for encryption when the drive is connected?

    Does the drive show as removable media when plugged in to the PC, if it just shows as an internal drive (which I find sometimes happens with my 32gb stick) then that won't be covered under the removable media policy (it would require a non-boot volume encryption policy).

    Try using a smaller pen drive and if you can post a screenshot of your policies for removable media that would be great.

    Thanks for your reply Toby.

    I have tried smaller USB drives, they behave the same - windows 10 reports them as "USB drives".

    I cannot see the option to prompt for encryption on the policy - I have added a screenshot below;

    Thanks,

    Hi David - When you installed Sophos on the client if you didn't use the switches or did a "Typical" install it may not have installed the extra functions needed for data exchange?

     

    If you choose "custom" then you can modify the following settings....

    Michael,

    This solved my problem. I had to set "synchronised encryption" as not available and all the location based file encryption to install.

    Everything appears to work as it did, along with the addition of the USB encryption now, many thanks.
