Episode 9 — Build metadata-safe compute patterns that survive real attacker pressure
This episode shifts from point fixes to resilient patterns: how to design compute deployments that remain secure even when an application layer fails. You’ll learn what “metadata-safe” means as an architectural objective, then apply it to common compute models like virtual machines, containers, and managed runtimes. We’ll cover best practices such as isolating sensitive workloads, minimizing outbound trust, controlling egress paths, and designing identity so compute units receive only the narrowest possible permissions for the shortest possible time. We’ll also address operational realities: how autoscaling, images, and configuration management can reintroduce risk if metadata assumptions get baked into templates. A scenario walks through a production service with a known SSRF exposure and demonstrates how metadata-safe identity and network boundaries keep the impact contained, which is exactly the kind of “defense in depth” reasoning the exam rewards.
