Discussion

If no authentication is required to establish personal hotspot connections (Wi-Fi and Bluetooth), an adversary may be able to use that device to perform attacks on other devices or networks without detection. A sophisticated adversary may also be able to exploit unknown system vulnerabilities to access information and computing resources on the device. Requiring authentication to establish personal hotspot connections mitigates this risk. Application note: If hotspot functionality is permitted, it must be authenticated via a preshared key. There is no requirement to enable hotspot functionality, and it is recommended this functionality be disabled by default. SFR ID: FMT_SMF_EXT.1.1 #41

Review the configuration to determine if the Samsung Android devices are enabling authentication of personal hotspot connections to the device using a preshared key. 

This validation procedure is performed on both the management tool and the Samsung Android device.

On the management tool, in the device restrictions, verify "Configure tethering" is set to "Disallow".

On the Samsung Android device: 
1. Open Settings >> Connections.
2. Verify "Mobile Hotspot and Tethering" is grayed out.

If on the management tool "Configure tethering" is not set to "Disallow", or on the Samsung Android device "Mobile Hotspot and Tethering" is not grayed out, this is a finding.
