The conventional method can make a reasonable analysis of common network attacks, but the reliability of the analysis is low under the virus propagation model. This paper proposes a new research method of computer network attack analysis based on the virus propagation model. Based on the relationship between the framework and daemon, the framework of the model for computer network attack analysis is set up, the attack analysis technology of computer network is determined, and the construction of the model for computer network attack analysis is completed. Computer attack objects and computer attack process are analyzed, and computer network attack analysis is carried out. Using the coverage test and the uncertainty test, the parameters of the reliability calculation variables are measured and the reliability calculation formula is replaced. It is concluded that the designed method of computer network attack analysis is 47.15% more reliable than the conventional analysis method, and is suitable for the network attack analysis under the virus propagation model.
