Apple visionOS 26 must not allow backup to remote systems (iCloud).

If a user is able to 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

Note: This requirement is not applicable if the authorizing official (AO) has approved users' full access to the Apple App Store for downloading unmanaged (personal) apps and syncing personal data on the device with personal cloud data storage accounts. The site must have an AO-signed document showing the AO has assumed the risk for users' full access to the Apple App Store.

Review configuration settings to confirm iCloud Backup 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 iCloud backup" is unchecked.

Alternatively, verify the text "<key>allowCloudBackup</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 visionOS management tool containing the policy. 5. Tap "Restrictions". 6. Verify "iCloud backup not allowed".

If "Allow iCloud backup" is checked in the Apple visionOS management tool, "<key>allowCloudBackup</key><true/>" appears in the configuration profile, or the restrictions policy on the Vision Pro does not list "iCloud backup not allowed", this is a finding.

Install a configuration profile to disable iCloud backup.
