Database intrusion detection based on user query frequent itemsets mining with item constraints
Yong Zhong, Xiaolin Qin · 2004
The paper presents a database intrusion detection algorithm based on user query frequent itemsets with item constraints. Firstly, the paper discusses the method to mine database user query frequent itemsets by using query template. Secondly, the paper discusses the constrained query templates that are used to reduce the number of frequent itemsets and improve system performance. At last, the paper discusses the algorithm design and its application example.
