Hi, my name is Tom Smykowski, I'm a staff full-stack engineer. I build and scale SaaS platforms to millions of users, working end-to-end from system architecture to frontend to mobile. On this blog I share what I learn about software engineering, application security, and building resilient systems.
What This Article Covers
In this article, we delve into the complexities of frontend security beyond the well-known mechanisms of Content Security Policy (CSP) and Cross-Origin Resource Sharing (CORS). By exploring additional security layers like CSRF, HSTS, and SRI, you'll gain insights into how these strategies work together to protect both frontend and backend systems against sophisticated attacks.
