Research on Computer Applications Based on Management of Network Information Security Technology

+ 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.

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.

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.

In the information environment, people's daily life and production methods have also changed accordingly. The application of information technology in people's daily life further enriches people's lifestyle and promotes the rapid development of social economy. While the Internet provides convenience for users, it also brings certain information security risks to users. Therefore, in the application process of computer network information technology, it is necessary to increase information security precautions. Only in-depth implementation of computer network information security protection work, can effectively avoid the occurrence of information security problems.

Today, with the continuous development of globalization, Internet technology has achieved unprecedented leap-forward development. On the one hand, data in all fields of society is growing at an explosive rate, and the development of the Internet has brought about profound changes in the way of data transmission, storage and processing. The development of big data and related technologies enables the transmission and exchange of massive data and information to cross the limitations of time and space, and people's dependence on databases and information systems is also increasing. However, on the other hand, the development of the Internet is also a double-edged sword. For network users, once the data information on the network is leaked in large quantities, there will be unpredictable information security risks. In this context, the problem of network information security has become particularly serious, and the impact and harm to the entire society are very huge. It is necessary to strengthen the response, processing and management to fully guarantee the security of the Internet. In the existing legal governance system for network information security, our country’s network security legislation has made rapid progress in recent years. In comparison, there is still a big gap. There are still many problems in China’s network legislation, law enforcement entities, administrative supervision, governance strategies, and social law-abiding awareness, and it is impossible to effectively prevent various security problems that may occur in a comprehensive manner. This article will find out the problems we have in the legal governance of network information security from the actual situation in China. And by comparing and referring to the latest foreign research progress, it puts forward feasible suggestions and measures for the current China’s network information security governance.KeywordsGlobalizationInternet developmentNetwork information securityRule of law governance

The modern world technology is civilized, globalized and modernized. The technological development of social networks and e-commerce applications produce larger data. This data communication is major task, because device to device communication need network terminal. This data transmission is not safe because of different types of tools and software available to destroy the existing network. In the field of network security during data transfer from one particular node to other node some security vulnerability is happened this is the one of the critical issue in this sector. The reason for this network security is different types of data attacks are happen in day to day life. It is easy to establish a new network but protecting the entire network is a big issue. This network security is generally two parameter first one is communication and second one is data automation. The network security field is directly or indirectly linked with the concept of data encryption. The development in this network security has taken us to a level that from signature again we came back to thumb print. For example maintain the data secure we use the lock system which is a finger print type. This technology helps us to protect the physical data theft, but logical data theft is still problem for data transmission.
