Description
Data on mobile devices is protected by numerous mechanisms, including user authentication, access control, and cryptography. When the data is backed up to an external system (either locally connected or cloud based), many if not all of these mechanisms are no longer present. This leaves the backed-up data vulnerable to attack. Disabling backup to external systems mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #40

Review managed Google Android 12 device configuration settings to determine if the capability to back up to a locally connected system has been disabled. This validation procedure is performed on both the EMM Administration Console and the managed Google Android 12 device. On the EMM console: COBO and COPE: 1. Open "Device owner management". 2. Verify that "Enable backup service" is toggled to OFF. On the managed Google Android 12 device: COBO: 1. Go to Settings >> System >> Backup. 2. Verify that Backup settings is "Not available". COPE: 1. Go to Settings >> System >> Backup. 2. Select "Work". 3. Verify that Backup settings is "Not available". If the EMM console device policy is not set to disable the capability to back up to a locally connected system or on the managed Google Android 12 device, the device policy is not set to disable the capability to back up to a locally connected system, this is a finding.

Review managed Google Android 12 device configuration settings to determine if the capability to back up to a locally connected system has been disabled.

This validation procedure is performed on both the EMM Administration Console and the managed Google Android 12 device.

On the EMM console:

COBO and COPE:

1. Open "Device owner management".
2. Verify that "Enable backup service" is toggled to OFF.

On the managed Google Android 12 device:

COBO:

1. Go to Settings >> System >> Backup.
2. Verify that Backup settings is "Not available".

COPE:

1. Go to Settings >> System >> Backup.
2. Select "Work".
3. Verify that Backup settings is "Not available".

If the EMM console device policy is not set to disable the capability to back up to a locally connected system or on the managed Google Android 12 device, the device policy is not set to disable the capability to back up to a locally connected system, this is a finding.
