Abstract

With the rapid development of information technology, computer networks play an increasingly critical role in modern society, yet they are simultaneously confronted with ever more severe security threats. To thoroughly investigate the security challenges and corresponding strategies in computer networks, this study aims to comprehensively analyze the primary security issues currently faced by computer networks and propose systematic solutions. By reviewing a substantial body of literature both domestically and internationally, as well as analyzing practical cases, and employing both qualitative and quantitative research methods, this study focuses on typical security problems such as viruses and trojans, hacker attacks, and data breaches. The findings indicate that traditional security measures are no longer sufficient to meet the complex and dynamic demands of network security, necessitating the establishment of a multi-layered and comprehensive defense system. This study innovatively proposes an intelligent monitoring and early warning mechanism based on artificial intelligence technology, which can perceive changes in the network environment in real-time and automatically adjust protection strategies; it also introduces blockchain technology to ensure the integrity and non-repudiation of data transmission. The results demonstrate that integrated protective measures incorporating emerging technologies can significantly enhance the level of network security, providing theoretical foundations and technical support for building a safer and more reliable computer network environment, and offering important references for the advancement of the cybersecurity field.
