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 ensure that logging is enabled, review supplementary content APPENDIX-C for instructions on enabling logging. 

Using pgaudit PostgreSQL can be configured to audit these requests. See supplementary content APPENDIX-B for documentation on installing pgaudit. 

With pgaudit installed the following configurations should be made: 

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

Add the following parameters (or edit existing parameters): 

pgaudit.log='ddl, role, read, write' 
log_connections='on' 
log_disconnections='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

Check Contents

As the database administrator, verify pgaudit is enabled by running the following SQL:

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

If the output does not contain "pgaudit", this is a finding.

Verify that connections and disconnections are being logged by running the following SQL:

$ sudo su - postgres
$ psql -c "SHOW log_connections"
$ psql -c "SHOW log_disconnections"

If the output does not contain "on", this is a finding.
