Abstract

The construction of network information security is not only the development security of network information technology in the era of big data, but also an important guarantee to ensure the safety and order of network environment. Based on this, this paper studies the network information security protection technology based on big data technology. In this paper, we first understand and analyze the current situation of network information security, and summarize the hidden dangers of network information security under the background of data. Secondly, on the basis of data mining in big data technology, this paper proposes a network information security protection technology based on big data technology. In order to study the network information security protection technology based on big data proposed in this paper, the simulation experiment is carried out on the simulation platform, and the method is compared with the traditional network protection technology and the big data based NAT network security protection technology, and the network defense ability and attack index are studied. The results show that the network defense capability of traditional network protection technology is 72%, and the attack index is 32%. The network defense ability of firewall network security protection technology based on big data is 89%, and the attack index is 13%. The network defense ability of NAT network security protection technology based on big data is 91% and the attack index is 17%. From the simulation results, we can see that the performance of network information security protection technology based on big data is better, and can play a better role in network information security protection.
