Fix Recommendation

Note: The following instructions use the PGDATA and PGVER environment variables. See supplementary content APPENDIX-F for instructions on configuring PGDATA and APPENDIX-H for PGVER.

Implement protective measures against unauthorized disclosure and modification during preparation for transmission.

To configure PostgreSQL to use SSL, as a database administrator (shown here as "postgres"), edit postgresql.conf:

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

Add the following parameter:

ssl = on

Next, as the system administrator, reload the server with the new configuration:

$ sudo systemctl reload postgresql-${PGVER?}

For more information on configuring PostgreSQL to use SSL, see supplementary content APPENDIX-G.

Check Contents

If the data owner does not have a strict requirement for ensuring data integrity and confidentiality is maintained at every step of the data transfer and handling process, this is not a finding.

As the database administrator (shown here as "postgres"), verify SSL is enabled by running the following SQL:

$ sudo su - postgres
$ psql -c "SHOW ssl"

If SSL is not enabled, this is a finding.

If PostgreSQL does not employ protective measures against unauthorized disclosure and modification during preparation for transmission, this is a finding.
