If no certificate information is found, this is not a finding.

NOTE: Certificates are only valid when their Status is TRUST. Therefore, you may ignore certificates with the NOTRUST status during the following check.

The DoD Cyber Exchange website contains information as to which certificates maybe acceptable (https://public.cyber.mil/pki-pke/interoperability/ or https://cyber.mil/pki-pke/interoperability/).
