Fix Recommendation

Configure the macOS system to apply gatekeeper settings to block applications from unidentified developers by installing the "com.apple.systempolicy.control" configuration profile.

Check Contents

Verify the macOS system is configured to apply gatekeeper settings to block applications from unidentified developers with the following commands:

/usr/bin/osascript -l JavaScript << EOS
function run() {
let pref1 = ObjC.unwrap($.NSUserDefaults.alloc.initWithSuiteName('com.apple.systempolicy.control')\
.objectForKey('AllowIdentifiedDevelopers'))
let pref2 = ObjC.unwrap($.NSUserDefaults.alloc.initWithSuiteName('com.apple.systempolicy.control')\
.objectForKey('EnableAssessment'))
if ( pref1 == true && pref2 == true ) {
return("true")
} else {
return("false")
}
}
EOS

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