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.

Using pgaudit the DBMS (PostgreSQL) can be configured to audit these requests. See 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, write, role'

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 (shown here as "postgres"), run the following SQL:

$ sudo su - postgres
$ psql -c "SHOW pgaudit.log"

If pgaudit.log does not contain, "ddl, write, role", this is a finding.
