1. Image and supply chain

  • Scan images for vulnerabilities and secrets.
  • Use minimal, trusted base images.
  • Generate an SBOM and manage dependencies.

2. Cluster hardening

  • RBAC and network policies (least privilege).
  • Pod security standards and admission control.
  • Secure the control plane and secrets.

3. Runtime

Monitor runtime behaviour and enforce policy; detect anomalous container activity.
