Vulnerability discussion

Screen mirroring allows the user to display device content to a compatible device (e.g., TV) over a Wi-Fi connection. Although this feature uses HDCP 2.x protocol and encryption of visual data to transmit data, vulnerabilities in the 2.0 and 2.1 protocol implementation can result in compromise of sensitive DoD data. Disabling this feature will mitigate this risk.SFR ID: FMT_SMF.1.1 #42

Check content

This validation procedure is performed on both the MDM Administration Console and the LG Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Allow Miracast" setting in the MDM console. 2. Verify the setting for the Miracast. On the LG Android device: 1. Unlock the device 2. Open the device settings. 3. Navigate to the Miracast setting: Settings >> Share & Connect >> Miracast 4. Verify the Miracast menu is disabled and the following message is displayed: Miracast is disabled by server policy. If the "Allow Miracast" setting is enabled, or if the user is able to enable the setting on the device, this is a finding.

Fix text

Configure the mobile device to disable Miracast. On the MDM Administration Console, disable the "Allow Miracast" setting.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
