Control Mechanism and Evaluation of Network Information Security in the Web-based Big Data Era

With the rapid development of the Internet, our lives have undergone earth-shaking changes. The scale of networks and big data continues to expand, and the network environment is becoming increasingly complex. The problem of network information security (NIS) is becoming more and more serious, and it is of great significance to study the control mechanism and evaluation of NIS. Starting from the background of the era of big data, this paper studies the web's NIS control mechanism and evaluation. This article first analyzes the functional and non-functional requirements for constructing the mechanism and evaluation system, and on this basis, constructs a NIS control mechanism and evaluation plan from physical security, network transmission security and data security. Finally, in order to verify whether the control mechanism and evaluation plan proposed in this paper are user needs, a system protection capability test was carried out. Test data shows that a total of 671 viruses were detected, worms accounted for 2.83%, backdoor viruses accounted for 1.79%, sabotage program viruses accounted for 35.17%, and advertisements accounted for 41.73%. It shows that the network virus warning function can operate normally.
