Discussion

Gatekeeper must be enabled. Gatekeeper is a security feature that ensures that applications are digitally signed by an Apple-issued certificate before they are permitted to run. Digital signatures allow the macOS host to verify the application has not been modified by a malicious third party. Administrator users will still have the option to override these settings on a case-by-case basis.

Check Content

Verify the macOS system is configured to enable gatekeeper with the following command:

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

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

Fix Text

Configure the macOS system to enable gatekeeper by installing the "com.apple.systempolicy.control" configuration profile.
