摘 要
随着信息技术的迅猛发展和数字化转型的深入推进，数据库作为信息系统的核心组件，承载着企业运营、用户信息、业务数据等关键信息资产。然而，数据库安全性问题日益凸显，成为制约信息系统健康发展的一大瓶颈。因此，本文旨在探讨数据库安全性问题及相应的加固措施。首先分析了当前数据库面临的主要安全威胁，包括数据泄露风险、数据完整性破坏、数据可用性挑战以及配置管理不当等问题。随后，详细阐述了数据库加固的多项关键措施，包括实施严格的数据访问控制、采用强身份验证机制、进行细粒度权限管理、应用数据加密与备份技术、防御数据篡改行为、监控事务日志以及加强安全配置与维护等。通过这些措施的综合应用，可以有效提升数据库系统的安全性，降低数据泄露和破坏的风险。本文的研究对于指导企业构建安全的数据库系统、保护数据资产免受侵害具有重要参考价值。

Abstract
With the rapid development of information technology and the deepening of digital transformation, the database, as the core component of the information system, carries the key information assets such as enterprise operation, user information and business data. However, the problem of database security is increasingly prominent, which has become a major bottleneck restricting the healthy development of information system. Therefore, this paper aims to explore the database security issues and the corresponding reinforcement measures. Firstly, we analyze the main security threats facing the current database, including data leakage risk, data integrity damage, data availability challenges, and improper configuration management. Subsequently, a number of key measures of database reinforcement are detailed, including implementing strict data access control, adopting strong authentication mechanism, fine-grained permission management, applying data encryption and backup technology, preventing data tampering behavior, monitoring transaction logs, and strengthening security configuration and maintenance. Through the comprehensive application of these measures, it can effectively improve the security of the database system and reduce the risk of data leakage and destruction. The research in this paper has important reference value for guiding enterprises to build a secure database system and protect data assets from infringement.
