What is an SQL injection, and how can it be prevented? 🔊
An SQL injection is a type of cyber attack that targets databases through vulnerabilities in a web application's input validation. Attackers insert malicious SQL code into input fields to manipulate database queries, potentially gaining unauthorized access to sensitive data. To prevent SQL injection, developers can implement parameterized queries, utilize prepared statements, and employ input validation techniques to sanitize user input. Regular security audits and code reviews also help strengthen defenses against such attacks.
