A production line security protection method based on a port mirror image and a block chain is characterized by comprising the steps that production line data communication content is acquired by adopting three port mirror image methods based on a production line security log generation technology of the port mirror image, and real-time viewing and historical security data playback can be carried out; according to production line security log distributed storage and management based on a block chain and a smart contract, an open source hyperledger framework Fabric is adopted to establish a trusted production line block chain platform environment, and the block chain and the smart contract are utilized to realize production line security log distributed storage and management. The method comprises the following steps: copying network flow data flowing through one or more ports of production line equipment to another or more ports for observation based on a port mirroring technology, analyzing and extracting co
