Why this module exists. Cloud-native security architecture — containers, Kubernetes, serverless, event-driven systems — has its own patterns distinct from traditional VM-based security. This module covers the architectural building blocks: workload identity, pod security, admission control, runtime detection, and the recurring patterns that hold across cloud providers.
Why this module exists. Cloud-native architecture moves so much of the trust boundary into automation that the security architecture must shift correspondingly. This module is the cloud-native-specific architectural reference.
The cloud-native trust model
Three observations that drive cloud-native security architecture:
- Workloads are ephemeral — pods come and go in seconds. Static-IP-based controls do not apply.
- Configuration is the perimeter — IaC and admission control are the controls, not firewalls.
- Multi-tenant by design — one cluster runs many workloads; isolation comes from configuration, not infrastructure.
