| 摘 要： | 针对网络数据库系统不断遭受攻击,而现有的各种安全技术,对数据库系统的安全保护还非常有限.分析了数据库系统入侵的主要来源,设计和实现了一个基于规则自学习的数据库安全增强模块,使所有的用户访问请求,必须经过安全规则的合法性确认,才允许访问数据库,模块的规则自学习功能使安全规则集不断完善,在易于实施的基础上,提高了数据库系统的入侵防御能力.

| Abstract: | The network database system is continuously intruded by all kinds of attacker,however the existing security technologies couldn't give protection very well to database system.On the basis of database system attack-source analysis,the model of security enhancement for database based on rule self-study is designed and established.The model is placed at the entrance of database so that unless an accessing request from user passing the authentication of its validity of the security rules,there is no execution f... |
