Abstract

With the rapid development of information technology, the security of computer network databases, as the core tool for information storage and processing, has become particularly important. This study first outlines the basic concepts of computer network databases, including their definition, classification, working principles, and widespread applications in modern society. Next, a detailed analysis was conducted on the security requirements faced by computer network databases, including data integrity, confidentiality, availability, and controllability. In response to these security requirements, this article further explores the security issues that currently exist in computer network databases, mainly including access control issues, data encryption and transmission issues, backup and recovery issues, as well as management and maintenance issues. In addressing these issues, this article proposes a series of targeted solutions. Firstly, strengthening access control is key to ensuring that data is not accessed without authorization. By improving identity authentication and permission management mechanisms, it is possible to effectively prevent illegal users from accessing sensitive data. Secondly, optimizing data encryption and transmission is an important means to improve data transmission security. By adopting advanced encryption algorithms and transmission protocols, it can ensure that data is not intercepted, tampered with, or leaked during transmission. Once again, improving backup and recovery mechanisms is an important measure to ensure data integrity and availability. Developing a scientific backup strategy and recovery process can quickly recover data in the event of data loss or damage. Finally, strengthening management and maintenance is the foundation for ensuring the long-term stable operation of database systems. By establishing a sound management and maintenance system, system vulnerabilities and security incidents can be identified and resolved in a timely manner, improving the security and stability of the system.
