Demilitarized Zones Join Defense-in-Depth in Plant Cyber Security MeasuresDemilitarized Zones Join Defense-in-Depth in Plant Cyber Security Measures

With Converged Plantwide Ethernet (CPwE) networks taking center stage and Internet of Things (IoT) initiatives potentially exposing even greater access to networks, securing plant and enterprise networks has become an enduring focus for which there are no absolute solutions.

Given the reality of successful and constant cyberattacks in the news, the best response is still combining layers of security using holistic, defense-in-depth measures that harden both the network configuration and architecture. But there is almost equal attention on the human equation and developing both technology solutions and procedures for properly authenticating and authorizing all types of user access at the network edge.
