Control modeling and optimization of network information security system based on deep learning data interaction

It is a multiple criteria problem to evaluate the security of information networks. However, one key issue which is not fully considered in extant studies is how to obtain the values of these multiple evaluation criteria, and in most evaluation models some redundant criteria values are calculated. Motivated by this, in the work we first use the pairwise comparison method to attain the values of each evaluation aspect of the security of information networks, and then develop a novel similarity-based M(1, 2, 3) approach to rate the security of alternative networks. Application study shows that the proposed approach could rate the overall security of alternative information networks and recognize the most vulnerable aspects of each information network, which provides good supports for making policies to enhance the security of alternative information networks.

+ Linear and dynamic models of the system of information security in social networks, taking into consideration the relationships between users, were studied and the resistance of the security system was analyzed. There is a practical interest in studying dependence of the behavior of the system of social network security on the parameters of users’ interaction. Dynamic systems of information security in social networks in the mathematical sense of this term were considered. A dynamic system refers to any object or process, for which the concept of state as a totality of certain magnitudes at a given time is unambiguously defined and the law that describes a change (evolution) of the initial state over time was assigned. The network of social interactions consists of a totality of social users and a totality of the relations between them. Individuals, social groups, organizations, cities, countries can act as users. Relations imply not only communication interactions between users but also relations of the exchange of various resources and activities, including conflict relations. As a result of research, it was found that the security systems of a social network are nonlinear. Theoretical study of the dynamic behavior of an actual object requires the creation of its mathematical model. The procedure for developing a model is to compile mathematical equations based on physical laws. These laws are stated in the language of differential equations. Phase portraits of the data security system in the MATLAB/Multisim program, which indicate the stability of a security system in the working range of parameters even at the maximum value of the impacts, were determined. Thus, the influence of users’ interaction parameters on the parameters of the system of social network security was explored. Such study is useful and important in terms of information security in the network, since the parameters of users’ interaction significantly affect, up to 100 %, the security indicator.

The presented article introduces the obtained solutions to the problems of information security in information networks at high-voltage electrical substations. The topic is driven by the ever-increasing apply of digital instrument transformers to measure electrical values on substations. These intelligent devices allow you to measure the currents and voltages in real time. The measured electrical instant values contained inside the data stream from digital instrument transformers must be delivered to the substation dispatching system in a strictly limited time. Exceeding the time delays of information transmission in the information network of a substation can lead to an accident at a critical infrastructure facility, which is an electrical substation. An increase in time delays during data transmission to the substation control system may be the results of information storms, which for various reasons may occur in the substation information network. This is one of the reasons for holding back the transition of the electric power sector of economy to the digital substations application. The presented software and hardware for digital instrumental transformers make it possible to ensure data transmission with an acceptable time delay in the event of an increase in the information load on the network. Laboratory studies and mathematical modeling confirm the results of the development.
