Device Control permissions for storage devices are used when you:

  • Allow access to USB storage devices, CD/DVD, SD cards, network drives, and Thunderbolt SATA storage devices. You can grant full access to these devices or limit the level of access.

  • Configure the list of approved USB storage devices. Device Control allows you to block access to all USB storage devices, except those that have been added to the list of approved devices. You can grant full access to the approved devices or limit the level of access.

The following table lists the permissions for storage devices.
