Security in System Design

In a world where cyber threats are constantly evolving, building a scalable system is not enough—it must also be secure by design.

In this episode, we break down the foundational pillars of system security, starting with Authentication & Authorization—how systems verify identity and enforce access control at scale. You’ll understand the difference between who you are (authentication) and what you’re allowed to do (authorization), and why both are critical in modern architectures.

We then dive into HTTPS and SSL/TLS, uncovering how data is encrypted in transit to prevent interception, tampering, and man-in-the-middle attacks. Learn how secure communication protocols form the backbone of trust on the internet.

Finally, we explore Secure API Design, covering best practices like input validation, rate limiting, token-based authentication (JWT), and protecting against common vulnerabilities such as injection attacks and unauthorized access.
