Explore zero-trust architectures for cloud computing and their implementation using WebAssembly and WireGuard in this 34-minute conference talk by Jordan Rash at CNCF. Learn how combining zero-trust principles with WebAssembly can enhance security in microservices architecture. Discover the benefits of micro-segmentation in isolating and securing individual application components. Examine how platforms like Tailscale utilize WireGuard to add security layers and minimize attack surfaces. Walk through the security advantages of WebAssembly, from user perspective to execution in a secure sandbox. Gain insights into leveraging the open-source Tailscale tsnet Go module to add end-to-end encryption and role-based access controls to WebAssembly modules without code changes.
