How can I protect my website from hackers and cyber attacks?

[emilycartar]

I want to learn the best practical ways to improve website security. I know basic things like using SSL, strong passwords, and regular updates, but I want to understand what steps developers actually follow to keep websites safe.

Please guide me on preventing SQL Injection, XSS, malware attacks, and unauthorized access. Any tools, best practices, or beginner-friendly resources would be helpful.
