A Research on Problems and Countermeasures of Computer Network Security in the Era of Big Data

Abstract

In the era of big data, the speed of information dissemination is accelerating and the amount of data is increasing. People in all corners of the world can quickly share information through the network, and the computer network has become an information superhighway for various applications. However, science and technology is a double-edged sword. Computer networks are facing security problems such as hacker attacks, virus intrusion and information leakage. In order to provide users with a safe network environment, this paper analyzes the security problems and security protection strategies of computer networks, and takes the network construction of colleges and universities as an example, puts forward the design of the network security system of colleges and universities.
