Description
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. Data sharing restrictions mitigate this risk. 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. SFR ID: FMT_SMF_EXT.1.1 #42, FDP_ACF_EXT.1.2

Check Text ( C-33924r592474_chk )
Review Samsung Android Work Environment configuration settings to determine if the access control policy prevents groups of application processes from accessing all data stored by other groups of application processes.

This procedure is for verifying that Calendar events created in the Work Environment are disallowed from being displayed in the Personal Environment Calendar and is applicable to COPE only.

This procedure is performed on the management tool Administration console only.

On the management tool, in the Work Environment RCP section, verify that "Sync calendar to personal" is set to "Disallow".

On the COPE Samsung Android device:
1. Open Settings >> Work profile >> Notifications and data.
2. Verify that "Export to personal calendar" is disabled and cannot be enabled.

If on the management tool the "Sync calendar to personal" is not set to "Disallow", or on the Samsung Android device "Export to personal calendar" is enabled or can be enabled, this is a finding.
