Review documentation on Samsung Android 8 with Knox and inspect the configuration on Samsung Android 8 with Knox to disable all Bluetooth profiles except for HSP, HFP, and SPP. This validation procedure is performed on both the MDM Administration Console and the Samsung Android 8 with Knox device. On the MDM console, do the following: 1. Ask the MDM Administrator to display the "Allowed Bluetooth Profiles" settings in the "Android Bluetooth" rule. 2. Verify the only profiles selected are HSP, HFP, and SPP. On the Samsung Android 8 with Knox device, do the following: 1. Attempt to pair a Bluetooth peripheral that uses profiles other than HSP, HFP, and SPP (e.g., a Bluetooth keyboard). 2. Verify the Bluetooth peripheral does not pair with the Samsung Knox for Android device. If the MDM console "Allowed Bluetooth Profiles" is set to profiles other than HSP, HFP, and SPP or the Samsung Android 8 with Knox device is able to pair with a Bluetooth keyboard, this is a finding. Note: Disabling the Bluetooth radio will satisfy this requirement.
