The OS X system must allow only applications downloaded from the App Store to run.


Overview

Finding ID Version Rule ID IA Controls Severity

Description
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 the OS X to verify that the application has not been modified by a malicious third party.
