基于数据库管理安全的研究

Study on database management security

从数据库安全的内涵出发,针对目前数据库面临的安全威胁,分析了影响数据库安全的因素,提出了数据库系统的安全体系三个层次结构。重点论述了这三个层次的数据库安全控制所采取的技术手段和措施,并在此基础上设计了一种新型数据库安全防护模型,使之能够实现数据库多层安全控制技术协作与管理,更可靠地保证数据库的安全;展望了数据库安全研究的方向。

Based on the consideration of current database security,factors influencing database security were analyzed.Three hiberarchy security system frameworks of database system were brought up.Technological measures controlling three hiberarchy frameworks security of database system were discussed.A new database security protection model was designed based on the above-mentioned.Thus,multilayer security control cooperation and management of database can be realized,and it can ensure the database security.Finally,the future tasks on database security were discussed.
