In order to improve the accuracy and stability of hospital information network security defense,a hospital information network security defense system based on data security gateway is proposed.Through the data security gateway to intercept the attack information of the hospital information network construction,an information transmission channel model of the hospital information network is constructed.The feedback equalization modulation method is used to balance the transmission channel of the hospital information network.The virus interception and control of the information security defense of the hospital information network are carried out with the association feature mining method According to the results of energy spectrum clustering analysis and filtering detection,the network security defense and virus attack detection of hospital information network are realized.The simulation results show that the intrusion detection ability of this method is strong,and the reliability and stability of security defense detection are good.
