SQL Injection Attacks Types, Prevention and Detection Techniques

SQL Injection Attacks (SQLIAs) is the oldest approach to harm the web applications. According to Acunetix Web application Vulnerability Report published in 2019, SQLIAs is approximate 11% of overall vulnerability [1]. As we know dynamic web applications are interactive web applications from which a user can gain some information and he can also store some information though that application. So web applications have a database to maintain user’s information. To deal with databases SQL is used at server end. A developer design some query to make interaction between user and database but if developer not validates the SQL query then a malicious user can insert some valid SQL code through web page and gain access to the database which was not intentionally designed by the developer. Using SQLIAs a malicious user can steal some personal information, perform some unintentionally financial operation and modify & destroy information from database. There are various ways of SQLIAs by which a malicious user gain access to the databases and there are many solutions for prevention and detection of SQLIAs.
