The paper analyzes modern methods of modeling impacts on information systems, which made it possible to determine the most effective approaches and use them to optimize the parameters of security systems. And also as a method to optimize data security, taking in the security settings account (number of security measures, the type of security subsystems, safety resources and total cost information) allows to determine the optimal behavior in the “impact-security”. Also developed special software that allowed to verify the proposed method.

In this paper the method of network-centric monitoring of cyberincidents was developed, which is based on network-centric concept and implements in 8 stages. This method allows to determine the most important objects for protection, and predict the category of cyberincidents, which will arise as a result of cyberattack, and their level of criticality.
