Understanding SQL Injection in Web Applications

In the world of web security, SQL injection is a serious threat to websites and applications. It occurs when an attacker inserts malicious SQL code into input fields on a website, aiming to gain unauthorized access to the database or execute harmful commands.

How can SQL Injection be Prevented in Web Applications?

The key to preventing SQL injection is to use parameterized queries or prepared statements. This involves using placeholders for user input and binding them to the parameters of the SQL query, making it impossible for attackers to inject malicious code.

Additionally, input validation and sanitization are crucial steps in preventing SQL injection. By validating and sanitizing user inputs before executing SQL queries, developers can minimize the risk of SQL injection attacks.
