The Samsung Knox for Android platform must be configured to implement the user-based enforcement setting: disable screen mirroring.
Overview

| Description |
|---|
| 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 |
