Ning Jiang, Lin Hu, Zhenyu Yin, Liaomo Zheng · 2018
According to the basic principle of defense in depth, the corresponding protection is carried out at different security zones. AS the key technology of perimeter defense, industrial firewall is used between enterprise zone and manufacturing zone. By utilizing an industrial demilitarized zone in industrial firewall, resources are shared between enterprise zone and manufacturing zone without direct traffic. To enhance the cyber security of industrial demilitarized zone, paired firewalls are applied. This paper will investigate the performance of industrial demilitarized zone based on main factors, such as response time, link utilization, throughput and FTP server load using the Riverbed Modeler (academic edition) simulation program.
