Fix Recommendation

Note: The following instructions use the PGDATA environment variable. See supplementary content APPENDIX-F for instructions on configuring PGDATA.

Integrate PostgreSQL security with an organization-level authentication/access mechanism providing account management for all users, groups, roles, and any other principals.

As the database administrator (shown here as "postgres"), edit pg_hba.conf authentication file:

$ sudo su - postgres
$ vi ${PGDATA?}/pg_hba.conf

For each PostgreSQL-managed account that is not documented and approved, either transfer it to management by the external mechanism, or document the need for it and obtain approval, as appropriate.

Check Contents

Note: The following instructions use the PGDATA environment variable. See supplementary content APPENDIX-F for instructions on configuring PGDATA.

If all accounts are authenticated by the organization-level authentication/access mechanism, such as LDAP or Kerberos and not by PostgreSQL, this is not a finding.

As the database administrator (shown here as "postgres"), review pg_hba.conf authentication file settings:

$ sudo su - postgres
$ cat ${PGDATA?}/pg_hba.conf

All records must use an auth-method of gss, sspi, or ldap. For details on the specifics of these authentication methods see: http://www.postgresql.org/docs/current/static/auth-pg-hba-conf.html.

If there are any records with a different auth-method than gss, sspi, or ldap, review the system documentation for justification and approval of these records.

If there are any records with a different auth-method than gss, sspi, or ldap, that are not documented and approved, this is a finding.
