Overview

Finding ID	Version	Rule ID	IA Controls	Severity

Description
The Nearby devices feature allows the user to share files with other devices that are connected on the same Wi-Fi access point using the DLNA technology. Even though the user must allow requests from other devices, this feature can potentially result in unauthorized access to and compromise of sensitive DoD files. Disabling this feature will mitigate this risk. SFR ID: FMT_SMF_EXT.1.1 #45

This validation procedure is performed both on the MDM console and the LG Android device. On the MDM console, do the following: 1. Ask the MDM administrator to display the "Allow DLNA" settings. 2. Verify the value is disabled. 3. Verify the policy has been assigned to all groups. On the LG Android device: 1. Select Settings >> Networks >> Share & connect 2. Try to launch "Media server". 3. Verify "Media server" is disabled and the following message is displayed: "DLNA discovery is unavailable by server policy." If on the MDM console "Allow DLNA" configuration is enabled or the LG Android device the "Media server" is not disabled, this is a finding.

Fix Text (F-72979r2_fix)
Configure the mobile operating system to disable DLNA. On the MDM Administration Console, disable "Allow DLNA".
