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 sensitive DOD information. To mitigate this risk, there are data sharing restrictions. 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; therefore, the administrator must be able to enable/disable the feature. Other exceptions include allowing any data or application sharing between process groups. SFRID: FMT_SMF.1.1 #42, FDP_ACF_EXT.1.2

Who does this work

13 NICE work roles and 8 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-268017r1031197_chk)

Review configuration settings to confirm "Allow documents from managed apps in unmanaged apps" is disabled. This check procedure is performed on both the Apple iOS/iPadOS management tool and the iPhone and iPad. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the iOS management tool, verify "Allow documents from managed apps in unmanaged apps" is unchecked. Alternatively, verify the text "<key>allowOpenFromManagedToUnmanaged</key><false/>" appears in the configuration profile (.mobileconfig file). On the iOS device: 1. Open the Settings app. 2. Tap "General". 3. Tap "VPN & Device Management". 4. Tap the Configuration Profile from the iOS management tool containing the restrictions policy. 5. Tap "Restrictions". 6. Verify "Opening documents from managed to unmanaged apps not allowed" is listed. If "Allow documents from managed apps in unmanaged apps" is checked in the iOS management tool, "<key>allowOpenFromManagedToUnmanaged</key><true/>" appears in the configuration profile, or the restrictions policy on the iPhone and iPad does not list "Opening documents from managed to unmanaged apps not allowed", this is a finding.

Fix Text (F-71844r1030803_fix)

Install a configuration profile to prevent non-DOD applications from accessing DOD data.
