摘　　要：为提高电力行业数据库应用系统跨网访问的安全性,介绍了数据库安全代理技术。采用远程方法调用(RMI)和Java数据库连接(JDBC)技术实现了数据库跨网访问系统。该系统支持常见的数据库产品,具有良好的通用性,支持普通的基于IP、端口和媒体访问控制(MAC)地址的安全过滤,同时支持基于结构查询语言(SQL)语义的安全过滤。检测表明,数据库安全代理系统能够满足数据库跨网访问需求,并提高了数据库应用系统跨网访问的安全性。With the development of computer network,the security problem of database inter-network access is becoming more and more serious. In order to enhance inter-network access security of database application system,a database security proxy technology is introduced in the paper. The database inter-network access system is implemented by using the remote method invocation （RMI） and Java database connectivity （JDBC） technology. The system proposed supports common databases and has fine generality. It can also support the security filtering based on IP,port,mandatory access control （MAC） address and structured query language （SQL） semanteme. Testing results show that the database security proxy system can satisfy the demand of database inter-network access and enhance the security of inter-network access of database application system.
