Methodology for Calculating Information Protection from Parameters of its Distribution in Social Networks

The article investigated dynamic models of the information security system in social networks, taking into account indicators of information dissemination in the social network, as well as analyzed the stability of the protection system.There is a practical interest in researching the behavior of the social network protection system against the value of indicators of information dissemination. The study is based on the nonlineability of the social network protection system. Theoretical study of the dynamic behavior of a real object requires the creation of its mathematical model. The procedure for developing a model consists in drawing up mathematical equations based on physical laws. These laws are formulated in the language of differential equations. As a result, the coordinates of the system state and its parameters were interconnected, which allows you to start solving differential equations under different initial conditions and parameters.To solve the system of nonlinear equations used: method of exceptions, joint solution of the corresponding homogeneous characteristic equation.Phase portraits of the data protection system in MatLab/Multisim are defined, which indicate the stability of the protection system in the working range of parameters even at the maximum impact value.
