What does SQL injection target in an application?

SQL injection primarily targets data-driven applications by inserting malicious SQL statements into input fields to manipulate the underlying database. This type of attack leverages vulnerabilities in an application's software that fails to properly validate or sanitize user input, allowing an attacker to execute arbitrary SQL code.

When a web application takes user input and directly uses it in SQL queries without adequate filtering, it opens up the potential for attackers to craft inputs that can affect the database’s behavior. This might include unauthorized access to data, deletion of records, or even administrative operations on the database.

Understanding this concept is crucial because it highlights the importance of implementing secure coding practices, such as using prepared statements and parameterized queries, to mitigate the risks associated with SQL injection. By focusing on how SQL injection attacks operate, developers and security professionals can better protect applications from these vulnerabilities.
