Vulnerability Discussion

The organization must issue or obtain public key certificates from an
organization-approved service provider and ensure only approved trust anchors are in the System
Keychain.

Check

Verify the macOS system is configured to issue or obtain public key certificates from an
approved service provider with the following command:

/usr/bin/security dump-keychain /Library/Keychains/System.keychain | /usr/bin/awk -F'"' '/labl/
{print $4}'

If the result does not contain a list of approved certificate authorities, this is a finding.

Fix

Configure the macOS system to issue or obtain public key certificates
from an approved service provider by obtaining the approved certificates from the appropriate authority
and install them to the System Keychain.
