Research on network information security model and system construction

Abstract

It briefly describes the impact of large data era on China’s network policy, but also brings more opportunities and challenges to the network information security. This paper reviews for the internationally accepted basic model and characteristics of network information security, and analyses the characteristics of network information security and their relationship. On the basis of the NIST security model, this paper describes three security control schemes in safety management model and the relationship between the security service and security mechanism in the network information security architecture. On this basis, a network information security system model is proposed, which is composed of three parts, namely, the core layer, the logic layer and the implementation layer. Finally, this paper points out that the network information security protection technology is important, but it is still indispensable that management is in place.
