Grade protection evaluation system of DCS (Distributed Control System)

The invention relates to the field of network security, in particular to a grade protection evaluation system of a DCS (Distributed Control System), which establishes a network protection grade table, connects an evaluation network, carries out network data transmission, and carries out network data acquisition on a to-be-evaluated system through a network information collection module. The method comprises the following steps: acquiring network information including attacked times, broken times, virus quantity, virus types and virus searching and killing speed of an evaluated network in a preset duration, analyzing and processing acquired network data, processing the network data into a security level, performing further level evaluation on the security level, and determining the security level of the evaluated network. According to the method, the defects and problems of the security system are obtained, a solution is provided, network data collection is adopted, the number of attacks, the number of broken-
