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 role, read, write, and ddl auditing are enabled: $ psql -c "SHOW pgaudit.log" If the output does not contain role, read, write, and ddl, this is a finding.
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.
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 can be made:
$ sudo su - postgres
$ vi ${PGDATA?}/postgresql.conf
Add the following parameters (or edit existing parameters):
pgaudit.log='ddl, role, read, write'
As the system administrator, reload the server with the new configuration:
$ sudo systemctl reload postgresql-${PGVER?}
