Mathematical model of web server protection is being proposed based on filtering HTTP (Hypertext Transfer Protocol) packets that do not match the semantic parameters of the request standards of this protocol. The model is defined as a graph, and the relationship between the parameters - the sets of vulnerabilities of the corporate network, the methods of attacks and their consequences-is described by the Cartesian product, which provides the correct interpretation of a corporate network cyber attack. To represent the individual stages of simulated attacks, it is possible to separate graph models in order to model more complex attacks based on the existing simplest ones. The unity of the model proposed representation of cyber attack in three variants is shown, namely: graphic, text and formula.
