分布式数据库中的安全措施

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.

The Secure Measure of Distributed Databases

The security of distributed databases is the foundation of resolving security problems of great management information systems. This paper analyzes the main security threatens the distributed databases confronted and proposes the basic demands of how to overcome them. Using the general means such as cryptography in the area of information security and from the three aspects of database storage, database access and database communication, and combined with the network management information system of military technology archives of equipment and Oracle DBMS, this paper expatiates the rules and measures of how to realize the security of distributed databases. Through the analysis, it is proved in order to realize security of distributed databases, the concrete security measures must be adopted and full consideration from the aspects of database storage, access and communication must be done, and finally different security services and technology must be applied.
