Research on Ontological Information Modeling for the Integration of Cyber and Physical Security in Power Systems

With the increasing complexity of power systems and the evolving nature of cyber threats, traditional security management methods are facing growing challenges. The effective integration of cyber security and physical security is key to enhancing overall safety. This study proposes an innovative ontological design approach aimed at constructing a comprehensive semantic network suitable for the integration of these two safety aspects within power systems. Initially, ontologies for cyber security and physical security were designed separately, defining the key entities and their attributes for each. Subsequently, these two ontologies were effectively combined to form a comprehensive ontology model that fully reflects the integration needs of cyber and physical security. This model not only reveals the intrinsic connections between cyber and physical security but also provides new strategies and methods for identifying and preventing cross-domain security threats. Through empirical analysis and case studies, this study validates the effectiveness of the proposed method in enhancing the security of power systems, especially in facilitating early detection and response to security incidents. The findings of this research offer a new perspective and tool for power system security management, holding significant theoretical and practical implications for the deep integration of cyber and physical security.
