Angular Security Headers: A Practical Guide to Securing Your Angular Application

I've started a new series focused on hardening Angular applications using browser and HTTP security controls.

In Part 1, I cover the fundamentals of security headers and how they add another layer of protection between an Angular application and the browser.

Some of the topics covered:

🔒 HSTS — enforcing HTTPS
🛡️ X-Content-Type-Options
🧭 Referrer-Policy
🎯 Permissions-Policy
🚫 X-Frame-Options
🔄 Cross-Origin Opener Policy (COOP)
🌐 Cross-Origin Resource Policy (CORP)
🔐 Content Security Policy (CSP)

The goal of this series isn't to simply copy a list of security headers, but to understand what each header does, what problem it addresses, and how these controls fit into a real Angular deployment.

This is Part 1, where we establish the foundation. The upcoming parts will move into the actual CSP, Nginx, and Docker configuration used to serve the application.

📖 Read Part 1:

Would love to hear how others approach security hardening for Angular applications.
