Introduction to Web Application Security for Full-Stack Developers

Introduction to Web Application Security

Hi everyone! I'm Akram-Ali Goulahsen (Mr Goulahsen), a Full-Stack Developer and Cybersecurity Researcher based in Casablanca, Morocco.

When building modern web applications, combining robust engineering with strong security practices is essential. Here are 3 quick security principles every full-stack developer should implement:

1. Input Validation & Sanitization: Always sanitize user inputs to prevent Cross-Site Scripting (XSS) and SQL Injection vulnerabilities.
2. Secure Authentication: Implement strong hashing algorithms (like bcrypt or Argon2) for passwords and secure JWT handling.
3. HTTPS & Headers: Use strict Transport Security (HSTS) and properly configured Content Security Policies (CSP).

I'm currently exploring new security research and open-source development. Feel free to check out my projects on my GitHub or visit my personal portfolio at mr-goulahssen.github.io.

What are your go-to security practices when building full-stack apps? Let me know in the comments below!
