Description

 Modern models for assessing the state of cyber security of information systems do not take into account the possibility of their recovery after cyber attacks with the aim of further effective use of funds to ensure the appropriate level of cyber security of the organization. Therefore, the need to solve the actual problem, its theoretical justification and practical implementation, related to ensuring the effectiveness of the functioning of information protection systems, built on the basis of appropriate models for assessing the state of cyber security of resources of information systems to determine the possibility of their recovery after the effects of cyber threats, taking into account the residual risk, is ripe intensity of cyber attacks. On the basis of theoretical and practical research carried out in the work, the following new results were obtained: models of the process of interaction between the means of implementing cyber attacks and means of cyber protection were developed to ensure the basic characteristics of the security of information system resources, in which due to the amount of residual risk and variation in the modes of operation or unauthorized use of means storage of information carriers and thus violation of its integrity, availability and confidentiality, allows to provide a quantitative and qualitative assessment of the state of cyber security; the model of the process of the interaction of protection means received further development, in which, due to the use of the model of the process of the interaction of the means of implementing cyberattacks with the means of cyber protection and the decomposition of the basic security characteristics of information system resources and taking into account the relevant indicators of the basic security characteristics in the process of cyber protection of information system resources, it is possible to increase the accuracy of dynamic assessment of dependence efficiency from the intensity of the eff
