SQL Injection Attacks

Fill in the blanks

SQL injection (SQLi) is a type of cybersecurity attack that targets web applications and can have serious consequences if successful. It occurs if an attacker is able to inject malicious into a database query . SQL injection attacks can lead to data breaches, unauthorized access, and data manipulation.



SQL injection attacks typically target web applications that accept user input, such as search boxes, login forms, and registration forms. Attackers enter into these input fields. For example, they might input ' OR 1=1 -- into a login form's username field. If the web application does not properly validate or , it may directly incorporate the attacker's input into SQL queries without proper checking. The attacker's input gets executed as part of a SQL query.



To prevent SQL injection, it is important to validate and sanitize all user input before using it in SQL queries. This includes using or prepared statements. Using parameterized queries or prepared statements provided by your database framework or ORM (Object-Relational Mapping) library can automatically handle input validation and prevent SQL injection. Additionally, using whenever possible encapsulates database logic and reduces the risk of SQL injection by separating user input from SQL code.
