A Survey of SQL Injection Attacks, Their Methods, and Prevention Techniques

Abstract

The vast majority of web applications' databases are vulnerable to SQL Query Injection Attacks, which let clients directly insert sensitive data. They carry out their operations by inserting nefarious SQL Injection Query codes into the client-side web API, which allows them to retrieve all the confidential and sensitive data from the database. SQL injection is a technique where web attackers post the malicious SQL injection Query, occupying the full admin login access of the web database, for malicious Input data modifications or deletion of the existing user User's Information. The goal of this technique is to change the structure and behavior of the query that the computer programmer has proposed. The examination of SQL injections, which target a Web application's front end to get access to its back-end database, It will address the implications, categorization, and techniques of these attacks. Then, two tactics have chosen to defend the database against SQL injection assaults. As a consequence, the design and development of any new SQL injection attacks for web application may use this work as a guide and reference
