Title
All digital certificates in use must have a valid path to a trusted Certification authority. (Cat II impact)
Discussion
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. Satisfies: SRG-OS-000066-GPOS-00034, SRG-OS-000403-GPOS-00182
Check Content
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
Fix Text
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/).

| CCI-000185 |
The information system, for PKI-based authentication, validates certifications by constructing and verifying a certification path to an accepted trust anchor including checking certificate status information. |
| CCI-002470 |
The information system only allows the use of organization-defined certificate authorities for verification of the establishment of protected sessions. |
