A Process Control Network (PCN) is a communications network layer that is a part of the Industrial Automation networks in Process Industries. This network is used to transmit instructions and data between control and measurement units and Supervisory Control and Data Acquisition ( SCADA ) equipment.

Need for PCN Hardening In a typical manufacturing plant, control system networks are crucial asset. PCN hardening is a method of improving security on network devices and reducing vulnerabilities through configuration changes applied directly to the network device e.g., a switch or router). It employs a standardized approach to implementing
