The macOS system must enforce On Device Dictation.

Dictation must be restricted to On Device Only to prevent potential data exfiltration.

The information system must be configured to provide only essential capabilities.

For Intel-based systems, this is not applicable.

Verify the macOS system is configured to enforce On Device Only Dictation with the following command:

/usr/bin/osascript -l JavaScript << EOS $.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\ .objectForKey('forceOnDeviceOnlyDictation').js EOS

If the result is not "true", this is a finding.

Configure the macOS system to enforce On Device Only Dictation by installing the "com.apple.applicationaccess" configuration profile.
