Efficient collection method for industrial control system network security data based on big data

Abstract

The invention discloses an efficient collection method for industrial control system network security data based on big data, and the method comprises the steps: collecting data through a data collection module, carrying out the security encryption of the collected data, judging the identity of a user of the collected data, and verifying the integrity and continuity of the collected data, thereby guaranteeing the security of the data, and improving the safety of the data; establishing a simulation model for part quality inspection equipment through a data accuracy verification model, comparing data collected from the simulation model with actual data, judging whether the data is modified or not, ensuring the accuracy of the data, and through the data problem tracing module, the reason for generating the deviation value between the data acquired from the simulation model and the actual data is called, so that the reason for generating the deviation of the data is corrected in time and the quality of the part is strictly controlled.

Description

technical field [0001] The invention relates to the technical field of big data industrial control systems, in particular to a method for efficiently collecting network security data of industrial control systems based on big data. Background technique [0002] The industrial control system is controlled through industrial automation, mainly through the integration of electronic, electrical, mechanical and other technical means. The three major control systems of the industrial control system are PLC, DCS and FCS, all of which are electronic systems operated by digital operations. When the industrial control system and the host computer perform data transmission, the security of the data is often poor, resulting in frequent data theft, and the speed of data upload is slow, and it is impossible to obtain the data of multiple interfaces at one time. The security of has been compromised, and it is impossible to know the authenticity of the uploaded data. [0003] In rail trans...
