[Abstract]:The prediction of network attack risk can ensure the safe and stable operation of computer network. To predict the network attack risk, it is necessary to calculate the influence degree of the network security element set on the opportunity index of the node, obtain the weighting function of each layer of the network, and complete the attack risk prediction. The traditional method gives the fusion rules of network security, determines the fusion priority of network attack risk data source, but neglects to obtain the weighting function of each layer of the network, which results in low prediction accuracy. A network information security attack risk prediction based on capability opportunity intention is proposed. In this method, the weighted fusion function of network security is defined from the basic operation of the network, the threat of the network and the vulnerability of the network, and the network security factor observations are given. The influence degree of the network security element set on the opportunity index of the node is calculated, the observation value of the network security factor is obtained, the weighting function of each layer of the network is obtained, and the risk prediction of network information security attack is established. Experimental results show that the proposed method has high modeling accuracy and can lay a foundation for improving the security level of computer network information.
