Abstract

Aiming at vulnerabilities mentioned above, this paper put forward a method to detect SQL injection attack based on SimHash algorithm. Firstly, it generated the initial SimHash fingerprint database after segmenting, hashing, weighting, merging, and dimension-reducing each SQL statement through self-learning process. Secondly, it used the initial fingerprint database to build the SimHash fingerprint database with index structure. Thirdly, it judged the legitimacy of each SQL statement by combining strict white list strategy which took "users' action is either black or white" as its core concept with the SimHash fingerprint database. Thereby, it lowered the risk of hacker's attacks bypassing the defense system. Experiments show that the detection method has a favorable performance of defensing SQL injection attack, including defensing some unknown ones, which is especially applicable for medium and small-sized websites.
