Abstract：With the rapid development of information technology, the problem of computer network security in colleges and universities is becoming increasingly prominent. As an important base for cultivating high-quality talents and scientific research and innovation, the network of universities carries a huge amount of data, including academic research, teaching management, student information and other important resources. However, in recent years, malware, virus attacks, phishing, hackers and other security threats occur frequently, bringing great challenges to the computer network security in universities. This not only affects the normal order of teaching and research, but also may cause the disclosure of sensitive information and even threaten national security. Therefore, this paper aims to analyze the main threats of computer network security in universities, and put forward the corresponding preventive measures. Through the thorough study of malware, virus attacks, phishing and hackers, this paper reveals the causes, characteristics and hazards of these threats. At the same time, combined with the actual situation of colleges and universities, this paper puts forward a variety of preventive measures, including preventing malicious software and virus attacks, preventing phishing and social engineering risks, preventing hacker intrusion and data theft, and strengthening internal threat management. These measures aim to build a three-dimensional and comprehensive computer network security protection system to ensure the network stability and information security.
