【摘要】 介绍了数据库中的入侵检测技术,设计了基于数据库的入侵检测系统模型,该模型采用新的结合距离度量思想的用户行为轮廓挖掘算法,考虑了给定数据库模式中数据结构和语义的数据库领域知识,对Apriori算法进行了扩展,挖掘出的频繁项集能更准确地反映用户行为轮廓.并将该模型应用到网站后台数据库的安全保护中,作为一个子系统用于实现后台数据库的入侵检测和保护,构建出一种新的网站综合保护解决方案.更多还原

【Abstract】 An intrusion detection system model for network database based on data mining algorithm with the notion of distance measure is proposed after introducing the technology of intrusion detection for database,the algorithm considers domain knowledge about the data structures and semantics encoded in a given database schema and is used to guide the search for frequent itemsets describing the working scopes of users.Then the model is applied to the new solution to the protection of network database for websites.更多还原
