Annotation: The article proposes a model for predicting the dynamics of a generalized indicator of the efficiency of the functioning of a corporate computer network in conditions of harmful information influences. The model is based on the representation of its dynamics in the form of a function of the level of performance of the corporate network at each moment of time from the specified interval. In this case, the level of network operability is determined by the operability of its elements and is described by an appropriate system of differential equations that take into account harmful effects and the process of eliminating their consequences. For these equations, under some simplifying conditions, analytical solutions are constructed, which greatly facilitates the process of forecasting the dynamics of the generalized efficiency indicator under consideration.
Keywords: corporate computer network, functioning, harmful information impacts, generalized efficiency indicator, dynamics, forecast, model.
