Library data protection and threat detection system based on network security

Traditional libraries may have security risks such as data breach, network attack and virus infection, which requires a library data protection and threat detection system based on network security to effectively manage and protect. Based on the premise of network security, this article focused on analysing library data protection and threat detection, constructing a library data protection and threat detection system using encryption algorithms, and testing its performance. According to the experimental results, it can be concluded that the average response time of unknown threats in the library data protection and threat detection system based on network security ranged from 0.4 s to 0.8 s under different test times. It can be seen that the system not only performs well, but also has very good user satisfaction. This article aimed to ensure the security of users' use of library resources and services through effective threat detection and data protection measures.
