英文摘要The invention discloses a Modbus communication access control method based on rule self-learning. The method is characterized in that the method is based on the Netfilter/iptables technical architecture, deep analyzing of the Modbus communication protocols in an industrial control system is achieved by the data packet deep analyzing technology, and access control of data communication between a Modbus master station and a Modbus slave station; the method works in a Modbus TCP/IP network and supports the TCP transmission protocol and the UDP transmission protocol; the method has a rule self-learning function, and automatic generation of Modbus access control rules can be achieved by setting self-learning time and self-learning thresholds. By the method, abnormal behaviors in Modbus communication can be detected and prevented, and reliability and safety of the industrial control system are guaranteed.
