Overview

Description
By default the enterprise administrator will install and enroll MDM on the device's owner user space. Since some policies configured by the MDM will only apply to the owner space, the user can bypass some of these policies by creating and switching to a guest user space. This can potentially result in compromise of the device and DoD data via installation of malicious applications. Disabling this feature will mitigate this risk. SFR ID: FMT_SMF_EXT.1.1 #45
