Title

The DNS server implementation must include only approved trust anchors in trust stores or certificate stores managed by the organization. (Cat II impact)

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 the DNS server implementation is configured to include only approved trust anchors in trust stores or certificate stores managed by the organization. If the DNS server implementation is not configured to include only approved trust anchors in trust stores or certificate stores managed by the organization, this is a finding.

Fix Text
