Description
Gatekeeper must be enabled. Gatekeeper is a security feature that ensures applications are digitally signed by an Apple-issued certificate before they are permitted to run. Digital signatures allow the macOS host to verify that 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.
ℹ️ Check
Verify the macOS system is configured to enable gatekeeper with the following command: /usr/sbin/spctl --status | /usr/bin/grep -c "assessments enabled" If the result is not "1", this is a finding.
✔️ Fix
Configure the macOS system to enable gatekeeper with the following command: /usr/sbin/spctl --global-enable
