数据库应用系统安防体系研究与设计

数据库应用系统的不安全因素除了数据库本身的安全性之外,主要表现在3个方面:数据存储在站点上的不安全因素,数据库应用程序的脆弱性以及数据库中敏感数据的危险性.提出了数据库应用系统安全防御的多层体系,将数据库应用系统安防体系划分为3个层次:决策层、代码层和数据加密层.首先保证存放数据库站点的安全性,其次保证访问数据库应用程序的健壮性和安全性,最后保护数据库中的数据的机密性.

Research and design of security protection architecture for database application system

Beside security problems of the database itself,DBAS's insecurity exists in three dimensions: Database site's insecurity factor,database application vulnerabilities,and dangers of sensitive data in the database.To solve the above three problems,a multi-level architecture is presented,which protect database application system security,and every level's function module is designed in this architecture.DBAS defensive system is divided into three levels: Decision-support level,code level,and data encryption lev...
