In order to enhance the network security protection level of intelligent substation, this paper puts forward a model of intelligent substation network security defense system through the analysis of intelligent substation network security risk and protection demand, and using example proved the feasibility and effectiveness of the defense system. It is intelligent substation network security protection provides a new solution.

In order to improve the information security level of intelligent substation, this paper proposes an intelligent substation information security assessment tool through the research and analysis of intelligent substation information security risk and information security assessment method, and proves that the tool can effectively detect it. It is of great significance to carry out research on industrial control systems, especially intelligent substation information security.

A system implementing real-time situational awareness through discovery, prevention, detection, response, audit, and management capabilities is seen as central to facilitating the protection of critical infrastructure systems. The effectiveness of providing such awareness technologies for electrical distribution companies is being evaluated in a series of field trials: (i) Substation Intrusion Detection / Prevention System (IDPS) and (ii) Security Information and Event Management (SIEM) System. These trials will help create a realistic case study on the effectiveness of such technologies with the view of forming a framework for critical infrastructure cyber security defense systems of the future.
