Abstract
With the rapid development of information technology, LAN is increasingly widely used in daily life and work. It carries a large number of data transmission and communication tasks, and the information value involved is increasing. However, the network security problems in the LAN environment are also increasingly prominent, such as network intrusion, data leakage, internal attacks and malware diffusion threats, which have brought huge losses and risks to enterprises and individuals. Therefore, this paper aims to explore the application research of computer network security protection technology in the LAN environment. Firstly, the types of network security threats and their risks in the LAN environment are summarized. Then, the paper deeply analyzes the core elements and hierarchical structure design of the current network security protection technology system. On this basis, this paper proposes application strategies such as enhancing network intrusion detection and defense capability, implementing data encryption and privacy protection technology, deploying internal security monitoring and malicious software defense system, and strengthening network equipment security and vulnerability management strategy. Finally, it emphasizes the importance of continuously updating and improving the network security protection technology system, and points out that strengthening the cultivation and education of network security awareness is the key measure to improve the level of computer network security in the LAN environment.
