The conventional network security solutions for manufacturing or factory automation devices are concentrated on protecting the internal networks from the attacks of external networks. Recently, however, so called Day-zero attacks are increased; the threat from internal devices such as notebooks, USB devices are as critical as attacks from external networks. Thus a new security solution is needed to protect manufacturing devices from both external and internal threat. To this purpose, we propose an edge-security system to provide cost effective, integrated, and simple end-point security solution specialized for automated manufacturing devices, which may avoid the shortcomings of NAC.
