Discussion

Public key infrastructure (PKI) certificates are certificates with visibility external to organizational systems and certificates related to the internal operations of systems, such as application-specific time services. In cryptographic systems with a hierarchical structure, a trust anchor is an authoritative source (i.e., a certificate authority) for which trust is assumed and not derived. A root certificate for a PKI system is an example of a trust anchor. A trust store or certificate store maintains a list of trusted root certificates.

Check Content

Verify TOSS 5 only uses trusted certificates using the following command:

 $ sudo trust list --filter=blocklist

    type: certificate
    label: Explicitly Distrust DigiNotar Root CA
    trust: distrusted
    category: authority

If the "label" field is not configured with "Explicitly Distrust DigiNotar Root CA", if any other labels are present, the line is commented out, or the line is missing, this is a finding.

Fix Text

Configure TOSS 5 to include only approved trust anchors in trust stores or certificate stores by adding certificates using the following command:

$ sudo cp /path/to/new-ca-cert.pem /etc/pki/ca-trust/source/anchors/

$ sudo /bin/update-ca-trust
