What is a 'SQL injection attack'?

• A. A technique used for data recovery
• B. An attack that targets databases with SQL queries
• C. A method of encrypting data
• D. A form of user authentication

Answer: (B)

A SQL injection attack is a type of cyber attack that specifically targets databases through malicious SQL queries. This occurs when an attacker inserts or "injects" malicious SQL code into a query that is then executed by the database. By manipulating the input fields of an application, attackers can gain unauthorized access to data in the database, potentially allowing them to view, delete, or modify sensitive information. This form of attack exploits vulnerabilities in web applications that do not properly validate or sanitize user inputs, leading to serious security breaches, data theft, or even complete system compromise. Understanding this type of attack is crucial for cybersecurity professionals, as it highlights the importance of secure coding practices and proper input validation techniques to protect databases from exploitation.
