| If all accounts are authenticated by the OS or an enterprise-level authentication/access mechanism and not by Oracle, this is not a finding. |
Review DBMS configuration to verify the certificates being accepted by the DBMS have a valid certification path with status information to an accepted trust anchor.
If certification paths are not being validated back to a trust anchor, this is a finding.

The database supports PKI-based authentication by using digital certificates over TLS in addition to the native encryption and data integrity capabilities of these protocols.
Oracle provides a complete PKI that is based on RSA Security, Inc., Public-Key Cryptography Standards, and which interoperates with Oracle servers and clients. The database uses a wallet that is a container that is used to store authentication and signing credentials, including private keys, certificates, and trusted certificates needed by TLS. In an Oracle environment, every entity that communicates over TLS must have a wallet containing an X.509 version 3 certificate, private key, and list of trusted certificates.
If the $ORACLE_HOME/network/admin/sqlnet.ora contains the following entries, TLS is installed.
WALLET_LOCATION = (SOURCE=
(METHOD = FILE)
SSL_VERSION = 1.2
(Note: This assumes that a single sqlnet.ora file, in the default location, is in use. Please see the supplemental file "Non-default sqlnet.ora configurations.pdf" for how to find multiple and/or differently located sqlnet.ora files.)
