Cisco and Rockwell strengthen OT/ICS security with visibility for converged plantwide ethernet (CPwE)

The turtle, protected by its hard shell, is a good metaphor for the security model used in most industrial networks. The industrial DMZ (iDMZ) is the shell that protects the soft, vulnerable center—the industrial control systems (ICS) the business depends on.
