Fix Recommendation

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

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

PostgreSQL can be configured to audit these requests using pgaudit. Refer to 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'

As the system administrator, reload the server with the new configuration:

$ sudo systemctl reload postgresql-${PGVER?}

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.
