In general, make sure that the PDNS process is unable to execute commands on your backend database.
Most database backends will only need SELECT privilege. Take care to not connect to your database as the 'root'
or 'sa' user, and configure the chosen user to have very slight privileges.
</p><p>
Databases empathically do not need to run on the same machine that runs PDNS! In fact, in benchmarks
it has been discovered that having a separate database machine actually improves performance.
</p><p>
Separation will enhance your database security highly. Recommended.
