Design of Detection and Defense Framework Based on SQL Injection

With the continuous development of Internet technology, Web applications have been widely used in all walks of life and have become an important role in people's daily lives. But at the same time, with the frequent storage and exchange of various types of information on Web applications, information security issues have become increasingly prominent. Among the numerous Web vulnerabilities, SQL injection brings great security risks and seriously damages users 'information privacy. This paper first systematically analyzes the injection principle and attack process of SQL injection. Based on the entire process from source code development to operation of the application program, combined with the code layer, platform layer and SQL injection detection and defense mechanism, a detection and defense framework based on SQL injection attacks is proposed, which improves the effectiveness of defense against SQL injection attacks.
