Vulnerability Discussion

The prompt for Siri during Setup Assistant must be disabled.

Organizations must apply organizationwide configuration settings. The macOS Siri Assistant Setup prompt guides new users through enabling their own specific Siri settings; this is not essential and, therefore, must be disabled to prevent against the risk of individuals electing Siri settings with the potential to override organizationwide settings.

Check

Verify the macOS system is configured to disable Siri Setup during Setup Assistant with the following command:

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

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

Fix

Configure the macOS system to disable Siri Setup during Setup Assistant by installing the "com.apple.SetupAssistant.managed" configuration profile.
