Discussion

Only DoW-approved external PKIs have been evaluated to ensure that they have security controls and identity vetting procedures in place which are sufficient for DoW systems to rely on the identity asserted in the certificate. PKIs lacking sufficient security controls and identity vetting procedures risk being compromised and issuing certificates that enable adversaries to impersonate legitimate users. The authoritative list of DoW-approved PKIs is published at https://cyber.mil/pki-pke/interoperability. This requirement focuses on communications protection for the DBMS session rather than for the network packet.

Check Content

Verify the "root.crt" certificate was issued by a valid DoW entity.

> openssl x509 -in /<PGDATA directory>/root.crt -text | grep -i "issuer". The default path for the PostgreSQL data directory (PGDATA) is /var/lib/edb/as<version>/data, but this will vary according to local circumstances.

Example:
> openssl x509 -in /var/lib/edb/as15/data/root.crt -text | grep -i "issuer"

If any issuers are listed that are not approved DoW certificate authorities, this is a finding.
