Security situation prediction method and system based on mes identification data interoperability system

Abstract

The invention relates to a safety situation prediction method and system based on an MES identification data intercommunication system. The method includes obtaining a security situation assessment model of the MES identification data intercommunication system; extracting network security situation elements of each enterprise node in the enterprise node layer according to the security situation assessment model; determining the situation threat value of each enterprise node according to the network security situation elements; According to the security situation assessment model, the strategy of bottom-up and layer-by-layer integration is adopted to integrate the situation threat value of each enterprise node to obtain the overall situation threat value of the MES identification data intercommunication system; The overall situational threat value and the autoregressive moving average model are used to determine the overall situational threat prediction value. The invention can accurately locate the safety loopholes in the MES identification data intercommunication system, and realize the evaluation of the safety situation in the system, thereby helping safety management personnel to formulate effective protection schemes.

Description

technical field [0001] The invention relates to the technical field of network security situation awareness, in particular to a security situation prediction method and system based on an MES identification data intercommunication system. Background technique [0002] Manufacturing Execution System (MES) is a workshop-oriented management information system located between the upper planning management system and the lower industrial control. And with the rapid development of industrial Internet technology, the MES-oriented identification data interoperability system was also proposed immediately. The application of this system can realize the interconnection and intercommunication of different MES systems of multiple enterprises, form a unified specification standard, and provide a more universal data interaction solution for MES systems. [0003] At present, the network security technologies applied in the MES system are generally security technologies such as firewall tec...
