Fix Recommendation

Remove and/or replace certificates with a status of TRUST whose issuer's distinguished name does not lead to a DOD PKI Root Certification Authority, External Root Certification Authority (ECA), or an approved External Partner PKI's Root Certification Authority.

Reference the DOD Cyber Exchange website for complete information as to which certificates may be acceptable (https://public.cyber.mil/pki-pke/interoperability/ or https://cyber.mil/pki-pke/interoperability/).

Check Contents

From the ISPF Command Shell enter:
RACDCERT CERT AUTH

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.

If the digital certificate information indicates that the issuer's distinguished name leads to one of the following, this is not a finding:
a) A DOD PKI Root Certification Authority
b) An External Root Certification Authority (ECA)
c) An approved External Partner PKI's Root Certification Authority

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/).
