Title

The EDB Postgres Advanced Server must uniquely identify and authenticate nonorganizational users (or processes acting on behalf of nonorganizational users). (Cat II impact)

Discussion

Nonorganizational users include all information system users other than organizational users, which include organizational employees or individuals the organization deems to have equivalent status of employees (e.g., contractors, guest researchers, individuals from allied nations). Nonorganizational users must be uniquely identified and authenticated for all accesses other than those accesses explicitly identified and documented by the organization when related to the use of anonymous access, such as accessing a web server. Accordingly, a risk assessment is used in determining the authentication needs of the organization. Scalability, practicality, and security are simultaneously considered in balancing the need to ensure ease of use for access to federal information and information systems with the need to protect and adequately mitigate risk to organizational operations, organizational assets, individuals, other organizations, and the nation.

Check Content

Open the "pg_hba.conf" file in a viewer or editor. The default path for the pg_hba.conf file is /var/lib/edb/as<version>/data (PGDATA), but this will vary according to local circumstances. If any rows have "trust" specified for the "METHOD" column, this is a finding.

Fix Text

Open the "pg_hba.conf" file in an editor. The default path for the pg_hba.conf file is /var/lib/edb/as<version>/data (PGDATA), but this will vary according to local circumstances. If any rows have "trust" specified for the "METHOD" column, delete the rows or change them to other authentication methods. Permitted methods in preferred order are: peer (local only), cert, ldap, sspi, pam, and scram-sha-256.
