Only DOD-approved external PKIs have been evaluated to ensure that they have security controls and identity vetting procedures in place that are sufficient for DOD systems to rely on the identity asserted in the certificate. PKIs lacking sufficient security controls and identity vetting procedures risk being compromised and risk issuing certificates that enable adversaries to impersonate legitimate users. The authoritative list of DOD-approved PKIs is published at https://www.cyber.mil/pki-pke. This requirement focuses on communications protection for the DBMS session rather than for the network packet.
If the DBMS will accept non-DOD approved PKI end-entity certificates, this is a finding.
Revoke trust in any certificates not issued by a DOD-approved certificate authority. Configure the DBMS to accept only DOD and DOD-approved PKI end-entity certificates.
