- Abstract
- A connection between an industrial control network and IT network can expose measurement equipment, control systems and important infrastructure components to various cyber-attacks. Many technologies have been proposed to protect industrial control networks against cyber-attacks and to provide confidentiality, integrity, and availability. Among the technologies, a physical unidirectional security gateway provides protection of critical systems by forcing unidirectional communication between the two networks. The unidirectional security gateway needs to provide safety and reliability, and to guarantee, the common criteria for information technology security evaluation is operated. In this paper, we propose a unidirectional security gateway satisfying security functional requirements derived from CC v3.1.
