ICS-security-zones

The authors discuss security protection for ICS networks, especially for physical devices using software defined security. This paper offers an SDSec-based approach to provide additional protection based on software defined zones. Different approaches are also discuss and presented. Understanding the nature of ICS/SCADA networks the authors present an approach to limit attacks and attack propagation on physical devices. Do you believe that a software defined approach works for ICS/SCADA systems/networks? Write a 4-5 page paper with supporting research (peer reviewed journals are required) that either supports an SDSec-based approach or dismisses this ICS/SCADA networks.
