LG Android 6.x must not allow backup to locally connected systems.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-66831	LGA6-20-101701	SV-81321r2_rule		Medium

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

This validation procedure is performed on both the MDM Administration Console and the LG Android device. On the MDM console, do the following: 1. Ask the MDM administrator to display the "Allow LG Backup" settings in the MDM console. 2. Verify the setting is disabled. 3. Verify the policy has been assigned to all groups. On the LG Android device: 1. Unlock the device. 2. Navigate to Settings >> General >> Backup & reset. 3. Select "LG Backup" and verify it is unavailable by server policy. If on the MDM console the "Allow LG Backup" setting is enabled and on the LG Android device the setting "LG Backup" is available, this is a finding.
