The EDB Postgres Advanced Server must only accept end entity certificates issued by DoD PKI or DoD-approved PKI Certification Authorities (CAs) for the establishment of all encrypted sessions.


Finding ID Version Rule ID IA Controls Severity
V-213630 PPS9-00-009100 SV-213630r508024_rule Medium
Only DoD-approved external PKIs have been evaluated to ensure that they have security controls and identity vetting procedures in place which are sufficient for DoD 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 DoD-approved PKIs is published at http://iase.disa.mil/pki-pke/interoperability. This requirement focuses on communications protection for the DBMS session rather than for the network packet.

Check Text ( C-14852r290202_chk )
Verify that the root.crt certificate was issued by a valid DoD entity.

> openssl x509 -in /root.crt –text | grep –i “issuer”. (The default path for the postgresql data directory is /var/lib/ppas/9.5/data, but this will vary according to local circumstances.)

If any issuers are listed that are not valid DoD certificate authorities, this is a finding.
Fix Text (F-14850r290203_fix)
Remove any certificate that was not issued by a valid DoD certificate authority.

Contact the organization's certificate issuer and request a new certificate that is issued by a valid DoD certificate authorities.
