SC-17 Public Key Infrastructure Certificates
All changes in this version
Title
Public Key Infrastructure Certificates
Control
a. Issue public key certificates under an [Assignment: certificate policy] or obtain public key certificates from an approved service provider; and
b. Include only approved trust anchors in trust stores or certificate stores managed by the organization.
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.
