This podcast episode offers an in-depth analysis of essential security patterns for cloud-native and microservices architectures. It thoroughly examines Zero Trust Architecture (ZTA), defining it as a "never trust, always verify" model crucial for modern distributed IT environments, and discussing its core principles, benefits, and trade-offs. The episode also explores Defense in Depth (DiD), a multi-layered cybersecurity strategy that complements ZTA by establishing redundant controls across various components to enhance resilience. Finally, it delves into Identity Federation, explaining how it enables streamlined and secure access across multiple distinct systems through centralized identity management, often leveraging protocols like SAML and OIDC
