In modern conditions, social networking serviceshave become one of the most popular mass media. Due to a large number ofadditional functions, besides providing social communication, services are usedto influence social and political processes. As a result of the spread ofcontent of destructive matter from anywhere in the world by intruders, threatsto the state's information security are being delivered. Currently there are novalid and effective methods to opposing the information impact on virtualcommunity actors in social networking services. Therefore, the scientific andapplied task of improving and further developing models of destructiveinformational influence in social networking services, which is going to allowto oppose threats to the state's information security timely, is especiallyurgent. In the article the model of destructive informational influence insocial networking services is offered on the basis of the system dynamicsmethod by J. Forrester. The conceptual basis of the system-dynamic model, whichincludes content, traffic content, and dynamics’ index number of content intime, is formulated. The approaches to constructing loops of linear andnonlinear feedback of actors’ interaction in the virtual communities of socialnetworking services are presented. Nonlinear analytical models of systemdynamics of informational influence in social Internet services as partialcases of second-order nonlinear differential equations are developed. Theapproaches to conducting a controlled transition of the information space ofsocial networking services through parametric control using a system-dynamicmodel of destructive informational influence are offered. The considered modelscan be used for constructing complex models of system dynamics of socialcommunication in virtual communities in the conditions of conductinginformation confrontation in order to ensure state’s information security insocial networking services.
