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.

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 

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

# SYSTEMD SERVER ONLY 
$ sudo systemctl reload postgresql-${PGVER?}

# INITD SERVER ONLY 
$ sudo service postgresql-${PGVER?} reload 

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

Deploy NSA-approved encrypting devices to protect the server on the network.

Check Contents

If PostgreSQL is deployed in an unclassified environment, this is not applicable (NA).

If PostgreSQL is not using NSA-approved cryptography to protect classified information in accordance with applicable federal laws, Executive Orders, directives, policies, regulations, and standards, this is a finding.

To check if PostgreSQL is configured to use SSL, as the database administrator (shown here as "postgres"), run the following SQL:

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

If SSL is off, this is a finding.

Consult network administration staff to determine whether the server is protected by NSA-approved encrypting devices. If not, this a finding.
