分布式数据库安全是解决大型管理信息系统安全问题的基础。本文分析了分布式数据库所面临的安全威胁 ,提出系统解决分布式数据库安全的基本要求 ,运用密码学和信息安全领域的常用技术手段 ,分别从数据库存储、数据库访问和数据库通信 3个方面 ,结合“军队装备科技档案信息网络管理系统”和 Oracle数据库 ,阐述实现分布式数据库安全的原则和措施。通过分析证明 ,实现分布式数据库安全 ,必须以具体的安全策略为指导 ,从数据库存储、访问、通信等各个方面综合考虑 ,应用不同的安全服务和安全技术加以实现。
Distributed database security is the foundation to solve the security problem of large management information system. This paper analyzes the security threats faced by distributed database and puts forward the basic requirements of system to solve the problem of distributed database security. By using common techniques in the field of cryptography and information security, we combine three aspects of database storage, database access and database communication respectively “Army Equipment Science and Technology File Information Network Management System” and Oracle database, described the principles and measures to achieve distributed database security. Through the analysis and proof, to realize the distributed database security, we must take the specific security strategy as the guide, considering all aspects of database storage, access, communication and so on, and implementing different security services and security technologies.
