Vulnerability discussion

Gatekeeper settings must be configured correctly to only allow the system to run applications downloaded from the Mac App Store or applications signed with a valid Apple Developer ID code. Administrator users will still have the option to override these settings on a per app basis. Gatekeeper is a security feature that ensures that applications must be digitally signed by an Apple issued certificate in order to run. Digital signatures allow Mac OS X to verify that the application has not been modified by a malicious third party.

Check content

To check to make sure only applications downloaded from the App Store are allowed to run, type the following code: system_profiler SPConfigurationProfileDataType | grep AllowIdentifiedDevelopers If 'AllowIdentifiedDevelopers' is not set to '1', this is a finding.

Fix text

This setting is enforced using the "Security Privacy Policy" configuration profile.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
