自律式容侵安全数据库模型

An intrusion tolerance model of database security based on autonomic computing

针对当前入侵容忍的数据库系统缺乏自适应能力的问题,采用了将自律计算、入侵容忍与传统数据库安全相结合的方法,提出了一个自律式容侵安全数据库模型.通过对数据库运行状态集的实时监测,自主评价访问可信度并对可疑访问进行自适应分流,并将高危访问进行特征分析并施加安全策略,最终保障数据库的安全运行.实验数据表明,该模型对本地和网络攻击可以实现有效稳定抵御,对于国家机构的数据管理、大型企业的管理控制等安全级别要求较高的领域有着重要的意义和价值.

Concerning lack of self-adaptation ability on existent intrusion tolerance database systems,this paper proposed an intrusion tolerance model of database security based on autonomic computing. By defending the attacks effectively, keeping the security of database system, and providing users with contin-uous service, the simulation results show that the model has great significance for the data management in national organization or large enterprises.
