摘 要
随着信息技术的迅猛发展，网络环境日益复杂多变，数据库作为信息存储与管理的核心组件，面临着前所未有的安全挑战。网络故障不仅影响数据的正常访问，还可能引发数据泄露、篡改等严重问题，因此研究数据库访问控制在网络故障防范中的角色与实现具有重要意义。本研究旨在探讨数据库访问控制在网络故障防范中的关键作用，通过分析现有访问控制机制的不足，提出一种基于动态权限调整和实时监测的访问控制模型。该模型结合了身份认证、权限管理以及行为审计等功能，能够在网络故障发生时及时调整用户权限，限制异常访问行为，保障数据库的安全稳定运行。研究采用理论分析与实验验证相结合的方法，构建模拟网络环境进行测试，结果表明所提出的访问控制模型能够有效提高数据库在网络故障情况下的安全性，降低数据被非法访问的风险。

Abstract
With the rapid development of information technology, the network environment is increasingly complex and changeable. Therefore, as the core component of information storage and management, the database is facing unprecedented security challenges. Network failure not only affects the normal access of data, but also may cause serious problems such as data leakage and tampering. Therefore, it is of great significance to study the role and implementation of database access control in network failure prevention. The aim of this study is to explore the key role of database access control in network fault prevention, analyze an existing access control mechanism and propose an access control model based on dynamic permission adjustment and real-time monitoring. The model combines identity authentication, authority management and behavior audit, which can timely adjust user rights in case of network failure, limit abnormal access behavior, and ensure the safe and stable operation of the database. The study adopts the method of combining theoretical analysis and experimental verification to build a simulated network environment for testing. The results show that the proposed access control model can effectively improve the security of the database in the case of network failure and reduce the risk of illegal data access.
