Discussion

The DOD standard for authentication is DOD-approved PKI certificates. Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate, and requires Authorizing Official ( AO) approval. In such cases, database passwords stored in clear text, using reversible encryption, or using unsalted hashes would be vulnerable to unauthorized disclosure. Database passwords must always be in the form of one-way, salted hashes when stored internally or externally to the DBMS.

Check Content

Execute the following SQL as the "enterprisedb" user:

SHOW password_encryption;

If the value is not "scram-sha-256", this is a finding.

Fix Text

Execute the following SQL as the "enterprisedb" user:

ALTER SYSTEM SET password_encryption = 'scram-sha-256';
SELECT pg_reload_conf();
