Title

The macOS system must disable iCloud Keychain Sync. (Cat II impact)

Discussion

The macOS system's ability to automatically synchronize a user's passwords to their iCloud account must be disabled. Apple's iCloud service does not provide an organization with enough control over the storage and access of data and, therefore, password management and synchronization must be controlled by an organization-approved service.

Check Content

Verify the macOS system is configured to disable iCloud Keychain Sync with the following command: /usr/bin/osascript -l JavaScript << EOS $.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\ .objectForKey('allowCloudKeychainSync').js EOS If the result is not "false", this is a finding.

Fix Text

Configure the macOS system to disable iCloud Keychain Sync by installing the "com.apple.applicationaccess" configuration profile.
