The article is written from the point of view of a white hat hacker, who explains the dangers of SQL injection attacks on web applications. The writer emphasizes the need for developers to take a multi-layered approach to security by implementing input validation, parameterized queries, and using a web application firewall (WAF). In addition, developers should follow secure coding practices and keep their application up to date with the latest security patches and updates. By following these best practices, developers can reduce the risk of SQL injection attacks and keep their web applications safe and secure.

This article provides a list of top 10 best practices for securing a web application from a backend developer's perspective. The best practices include using HTTPS, implementing input validation, using parameterized queries, password hashing, two-factor authentication, limiting access, using security headers, securing APIs, regularly updating dependencies, and using logging and monitoring. These practices help prevent common web application attacks, such as SQL injection and cross-site scripting, and maintain user trust by ensuring the security of sensitive information. It is essential to continually update and monitor web application security to prevent potential threats.
