Samsung Android's Work profile must be configured to disable exceptions to the access control policy that prevent application processes and groups of application processes from accessing all data stored by other application processes and groups of application processes.
An XCCDF Rule
Description
<VulnDiscussion>App data sharing gives apps the ability to access the data of other apps for enhanced user functionality. However, sharing also poses a significant risk that unauthorized users or apps will obtain access to DOD sensitive information. To mitigate this risk, there are data sharing restrictions, primarily from sharing data from personal (unmanaged) apps and work (managed) apps. If a user is allowed to make exceptions to the data sharing restriction policy, the user could enable unauthorized sharing of data, leaving it vulnerable to breach. Limiting the granting of exceptions to either the Administrator or common application developer mitigates this risk. Copy/paste of data between applications in different application processes or groups of application processes is considered an exception to the access control policy and therefore, the Administrator must be able to enable/disable the feature. Other exceptions include allowing any data or application sharing between process groups.
