Research on Network Security Dynamic Defense Technology for Power Iot Terminals

This project intends to establish an active security defense system that combines risk analysis, security evaluation and security defense technologies to realize dynamic monitoring and defense of power grid. The access situation of power grid users is analyzed in detail. Because the password system is not complete, the protection measures are insufficient, which increases the risk of the user's network information being stolen. The new energy access server is used for platform verification, and all the collected component data is transmitted to the corresponding verification component. The data from the interaction with the client is transferred to the validation server. The access gateway executes the command to complete the secure access to the terminal. The information controller passes the request to the policy enforcement node and transmits its authenticated identity to the IoT server. Data is collected according to the network access node protocol, and an encrypted transmission path is constructed to achieve remote monitoring and access. The simulation results show that this method can ensure the user access and remote monitoring, thus ensuring the stable operation of the whole system.
