According to Tianrongxin, the Tianrongxin Industrial Internet Security Range System was released. As a comprehensive simulation and exercise platform specially built for industrial Internet security, it has the core ability to build large-scale and complex training environments. It uses cutting-edge virtualization technology to accurately simulate multi-industry devices and business scenarios, and combines physical devices to achieve hybrid network orchestration, thus constructing a comprehensive and cross-industry panoramic simulation range. In this secure firing range environment, verification and penetration testers can simulate various cyber attacks to comprehensively evaluate the security of industrial networks; operators and maintenance personnel can perform defensive operations such as surface convergence and security reinforcement in real time to ensure that they can respond quickly in the face of potential threats.
