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. Online certificate status protocol (OCSP) is preferred over certificate revocation lists (CRLs). If OCSP is used this requirement is not applicable.

CRL must only be used as a fallback if an OSCP function is not available.

Review the application documentation and deployed configuration to determine whether the application includes only approved trust anchors in trust stores or certificate stores managed by the organization.

If the application does not include only approved trust anchors in trust stores or certificate stores managed by the organization, this is a finding.
