EP11-00-004200 - The EDB Postgres Advanced Server must uniquely identify and authenticate organizational users (or processes acting on behalf of organizational users).

Information

To assure accountability and prevent unauthenticated access, organizational users must be identified and authenticated to prevent potential misuse and compromise of the system.

Organizational users include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors). Organizational users (and any processes acting on behalf of users) must be uniquely identified and authenticated for all accesses, except the following:

(i) Accesses explicitly identified and documented by the organization. Organizations document specific user actions that can be performed on the information system without identification or authentication; and
(ii) Accesses that occur through authorized use of group authenticators without individual authentication. Organizations may require unique identification of individuals in group accounts (e.g., shared privilege accounts) or for detailed accountability of individual activity.

Solution

Open '<postgresql data directory>\pg_hba.conf' in an editor.

Note that the default location for the pg_hba.conf file is in the postgresql data directory. The location of the pg_hba.conf file for a running postgres instance can be found using the following command run from a Windows command prompt:

psql -d <database name> -U <database superuser name> -c 'SHOW hba_file'

where, <database name> is any database in the EDB postgres instance and <database superuser name> is a database superuser. By default, a database named 'edb' and a superuser named 'enterprisedb' are installed with EDB Postgres Advanced Server (EPAS).

If any rows have 'trust' specified for the 'METHOD' column that are not documented and approved, delete the rows or change them to other authentication methods.

Permitted methods in preferred order are: peer (local only), cert, ldap, sspi, pam, sha-256-scram, md5
