To ensure the safety and reliability of the industrial control system,this paper designs a malicious node attack detec-tion system in industrial control network based on improved FastICA algorithm.In the industrial control network server clus-ter,the hardware module of malicious node attack detection system in industrial control network is designed from four parts,network server,attack behavior de-duplication module,malicious node identification module and Fabric attack behavior detec-tion component.On this basis,this paper calculates the initial value of Fast,tallies the uncertainty of ICA units,and improves the FastICA algorithm.Therefore,combining relevant attack behavior information,the attack separation conditions for mali-cious node are derived.The experimental results show that by distributing the test data according to a 1∶1 load standard,the designed system can effectively detect malicious node attack behavior,and the obtained real-time detection quantity value of ma-licious node has a fitting degree close to 100％with the rated value,which can better maintain the operational stability of the network system.
