摘　　要：目前国内的数据库应用系统 ,多数是在Client/Server模式主流商用数据库产品环境下进行开发和运行 ,其安全级别较低。由于不可能对商用数据库产品进行修改 ,从应用实际出发 ,提出由数据库安全代理增强数据库应用系统的安全性。在分析数据库应用系统特点和安全需求基础上 ,结合实际系统研究了数据库安全代理的功能和在MIDAS技术基础上的设计和实现 。Most database application systems are developed and operated under the environment of current C/S business database products, therefore the security is low. It is impossible to modify the business database products, according to the realization, database security proxy is put forward to enhance the security of database application system. Based on the characteristics and security requirement of database application system, the authors study the function of database security proxy and its design and realization based on Borland′s MIDAS (Multi-Tier Distributed Application Services Suite), and analysis and experiments are done on the ability of preventing main attack methods to database.
