Challenges and Solutions for Network Security in the Information Age

In recent years, with the rapid development of big data, the Internet of Things, artificial intelligence, 5G technology and new next-generation network technologies, network information technology is profoundly changing people's way of production and life. While internet technology brings convenience to our life and work, the ensuing network security issues such as data security, application security and system security are also becoming increasingly prominent. Therefore, network security technology, as the main means to maintain network information security, has begun to receive attention from the network security departments of various countries. From the perspective of network security governance and defense, this paper summarises the current status of network security construction and governance regulations in various countries, outlines the key technical features of firewalls, intrusion detection, data encryption and virtual private networks currently used in network security, and lays the foundation for mastering network security management technologies. Through the analysis of the current situation of network security, the challenges faced by network security in terms of hardware and software security, data security, hacker attacks and virus invasion are presented. Given the above challenges, this article gives solutions for establishing a security defense system, data management system and prediction and early warning system, to provide a reference for the construction of network information security.
