Description
If a user can configure the security setting, the user could inadvertently or maliciously set it to a value that poses unacceptable risk to DOD information systems. An adversary could exploit vulnerabilities created by the weaker configuration to compromise DOD sensitive information. SFR ID: FMT_MOF_EXT.1.2 #40

ℹ️ Check
Review configuration settings to confirm "Allow managed apps to store data in iCloud" is disabled. This check procedure is performed on both the Apple visionOS management tool and the Vision Pro. 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 Apple visionOS management tool, verify "Allow managed apps to store data in iCloud" is unchecked. Alternatively, verify the text "<key>allowManagedAppsCloudSync</key> <false/>" appears in the configuration profile (.mobileconfig file). On the Vision Pro: 1. Open the Settings app. 2. Tap "General". 3. Tap "VPN & Device Management". 4. Tap the configuration profile from the Apple visionOS management tool containing the restrictions policy. 5. Tap "Restrictions". 6. Verify "Managed apps cloud sync not allowed" is listed. If "Allow managed apps to store data in iCloud" is checked in the Apple visionOS management tool, "<key>allowManagedAppsCloudSync</key> <true/>" appears in the configuration profile, or the restrictions policy on the Vision Pro does not list "Managed apps cloud sync not allowed", this is a finding.
