Abstract
With the advancement of Industry 4.0 and the widespread application of Internet of Things (IoT) technologies, industrial control systems (ICS) are progressively evolving towards networking and intelligence; however, this transformation has also led to increasingly severe cybersecurity risks. This study focuses on ICS, conducting an in-depth analysis of the existing cybersecurity threats within current systems and their underlying causes, while exploring the evolution trends of attack methods through practical case studies. By integrating literature reviews with empirical analyses, the research identifies the inadequacies of existing protective technologies and proposes a comprehensive protection strategy based on a multi-layered defense system. This strategy incorporates key technologies such as behavior analysis, anomaly detection, and encrypted communication, aiming to enhance the system's active defense capabilities and dynamic response levels. The results indicate that the proposed protective measures effectively reduce the success rates of common attacks while significantly improving the security and stability of the system. Furthermore, this study innovatively introduces artificial intelligence algorithms for real-time monitoring and prediction of potential security threats, thereby achieving a transition from passive defense to proactive early warning. This approach not only addresses the deficiencies of traditional protective methods in terms of flexibility and adaptability but also provides new insights into the secure design of future industrial control systems. Overall, this research clarifies the core issues of cybersecurity in industrial control systems, proposes targeted solutions, and verifies their feasibility and effectiveness, making significant contributions to theoretical research and technical practices in related fields.
