A Security Architecture Model of Oil and Gas SCADA Network Based on Multi-Agent

Modern industrial automation control network SCADA system is facing more and more serious security threat. In order to meet the demand for oil and gas SCADA system security defense, by analyzing the security risk in oil and gas SCADA system and advantage of multiagent technology, formalization description security defense architecture based on multiagent is presented and the roles and tasks in the architecture are described and SCADA security defense framework based on multi-agent is designed, finally, simulation model based on agent security attack and defense is given. With the experimental simulation using neural network recognition algorithm, the reliability and validity of the model are verified by comparing detection rate and false rate. Compared with the traditional security and defense, this system makes full use of many advantages of the multi-Agent architecture, and has the advantages of accurate detection, high detection efficiency and timely response.
