Review the configuration to determine if the Samsung Android devices are either enabling data at rest protection for removable media, or are disabling their use. This requirement is not applicable for devices that do not support removable storage media. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the device restrictions, verify that "Mount physical media" is set to "Disallow". On the Samsung Android device, verify that a microSD card cannot be mounted. The device should ignore the inserted SD card and no notifications for the transfer of media files should appear, nor should any files be listed using a file browser, such as Samsung My Files. If on the management tool "Mount physical media" is not set to "Disallow", or on the Samsung Android device a microSD card can be mounted, this is a finding. If the deployment requires the use of micro SD cards, follow this alternative procedure: On the management tool, in the device restrictions, verify "Enforce external storage encryption" is set to "Enable". On the Samsung Android device, do the following: 1. Insert a freshly formatted microSD card. 2. Verify that a prompt appears to encrypt the microSD card. 3. Perform the encryption. 4. Remove and reinsert the microSD card and verify that a notification appears stating that the mounted microSD card is encrypted. If on the management tool "External storage encryption" is not set to "Enable", or on the Samsung Android device a microSD card can be used without first being encrypted, this is a finding
