分布式数据库安全管理研究

随着计算机网络的迅速发展和广泛应用,数据的安全性越来越重要。计算机系统和网络的安全是分布式数据库系统安全的基础。作为分布式数据库系统数据管理的核心,分布式数据库管理系统也必须有一整套完整而有效的安全机制。本文首先阐述了数据库安全的概念,讨论了不安全因素和安全需求,然后给出了安全策略在SQLServer的实现方法。通过该安全策略的运用,可保证分布式数据库系统的安全运行。

Research of Security Management for DDBS

With rapid development and extensive application of computer network, the importance of data security is increasing. Computer system and network security are basis of security of distributed database system. As the core of data management for distributed database system, distributed database management system must have a set of comprehensive and effective security mechanism. This paper first describes the concept of database security, then discusses the factors of insecurity and security needs, lastly it carries out the implementation of such security strategies in SQL Server system. The conclusion is that the security operation of DDBS is ensured by using the security strategies.
