Converged Plantwide Ethernet or CPwE describes an architecture that enables the implementer to tie together or converge ICS networks with enterprise networks in an efficient, convenient, and secure way. Security is engineered into the architecture with segmentation. By segmenting an ICS into functional zones, security perimeters are established with the ability to control, restrict, and inspect traffic between zones.
To accomplish segmentation, CPwE adopted a framework that was developed by the International Society of Automation ISA-99 Committee for Manufacturing and Control Systems Security:
“CPwE is an ...
