Vulnerability discussion

Backups to remote systems (including cloud backup) can leave data vulnerable to breach on the external systems, which often offer less protection than the Samsung Android 8 with Knox. Where the remote backup involves a cloud-based solution, the backup capability is often used to synchronize data across multiple devices. In this case, DoD devices may synchronize DoD sensitive information to a user's personal device or other unauthorized computers that are vulnerable to breach. Disallowing remote backup mitigates this risk. Google Backup is a device-wide control and, if enabled, will back up both personal and Knox data to personal Google cloud storage accounts.SFR ID: FMT_SMF_EXT.1.1 #40

On the Samsung Android 8 with Knox device, do the following: 1. Open the device settings. 2. Select "Accounts". 3. Select "Backup and restore". 4. Verify "Back up my data" is disabled and cannot be enabled.
