SQL Server 2000数据库安全管理策略

SQL Server 2000 Database Security Management Strategy

Microsoft SQL Server2000是比较成熟的大型关系数据库管理系统(DBMS),其理论基础建立在强大的关系模型理论基础之上,其安全机制建立在数据库的认证、授权等策略之上,其认证又分为操作系统(OS)级和数据库认证两个层次。从SQL Server 2000安全模型着手,针对该数据库管理系统存在的数据安全问题,从多个方面进行探索性总结和分析,并给出详尽的解决方案,这对实现数据的保密性、完整性和有效性极其重要。

Microsoft SQL Server 2000 is a relatively mature large-scale relational database management system （DBMS）, whose theoretical foundation is established on the strong relationship model, and whose security mechanism is established on the database authentication, and authorization strategies. The certification is divided into operating system （OS） level and two levels of certification database. The artical, from the perspective of SQL S2000 security model, in view of the existence of the database management system of data security issues, and from many aspects of the exploration summary and analysis, gives a detailed solution here.
