Description
The origin of a certificate, the Certificate Authority (i.e., CA), is crucial in determining if the certificate should be trusted. An approved CA establishes grounds for confidence at both ends of communications sessions in ongoing identities of other parties and in the validity of information transmitted.

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/). Examples of an acceptable DoD CA are: DoD PKI Class 3 Root CA DoD PKI Med Root CA
