The aim of the work is statistical analysis of the results of simulation modeling of the information security incident response team (ISIRT) depending on the parameter of increasing the intensity of the flow of information security incidents. ISIRT is considered as a queuing system in conditions of increasing load intensity. As input parameters for simulation the intensity of receipt of applications, characteristics of increase of intensity, characteristics of service of applications of ISIRT are used. The developed computer program sets random values of these parameters, distributed according to the indicator law. For each set of values, a set of stationary values is calculated, which characterizes the efficiency of ISIRT, as selected probabilities of operating modes and expectations. The program performs statistical analysis of the obtained values. As a result of the simulation, quantitative values were obtained both for the average values ​​and for the indicators of variability of characteristics that describe the effectiveness of ISIRT. The simulation showed the ability to predict the statistical patterns of cyber-attacks on the effectiveness of ISIRT. Tracking the statistical characteristics of incidents in the process of deploying the current cyber-attack, it is possible in the process of cyber defense to replace one ISIRT with another, the statistical characteristics of which will provide the required level of protection. To implement this approach, the developed software can be used.
