I have been trying to secure through CDRW devices code.

I have tried setting the dacl on the file \\.\E:, so only a certain group of users can access. While this works fine and access is correctly blocked via explorer.exe and the imapi service is correctly blocked from writing to the device (System is only given read access), I have found that 3rd party applications such as Roxio and Nero can still burn correctly.

I have also tried setting the security at the device level using SetupDiSetDeviceRegistryProperty and SPDRP_SECURITY_SDS. Again access is correctly granted for explore.exe and imapi.exe but Roxio and Nero still have access.

Anyone have any ideas how this is possible and two if there is some other way I can secure a cdrw against unauthorized access.

Thanks
