Computer Network Security and Preventive Measures Based on Big Data Technology

Computer network security (NS) is the most concerned problem of society and people. With the increasing amount of network information, the computer NS management in the era of Big Data (BD) is very important, and has become the primary topic of NS management. This paper studies the computer NS and preventive measures based on BD technology. In this paper, through the method of literature analysis and questionnaire survey, 150 teachers and students majoring in Computer Science in our school were investigated to understand the current situation of computer NS in China and the solutions. The research results show that the computer NS problems in the era of BD are mainly divided into three aspects: the security problems caused by human factors account for about 30%, the security problems in data transmission account for about 45%, and the security problems of computers themselves account for about 25%. In view of these NS problems, this paper details the NS problems, and proposes corresponding solutions to these problems, so as to effectively improve the level of NS management and promote the efficient development of computer network technology(NT).
