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.

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?}

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 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.
