Security continues to emerge as a key focus in manufacturing. Open standards bring plenty of benefits, but opening anything up always brings a few threats. A growing number of tools make it simpler to set up good firewalls, accounting for the differences between factories and front offices.

It only takes one mishap to wreak havoc and convert the victims to true believers.
