Cluster Setup15%

Use Network security policies to restrict cluster level access
Use CIS benchmark to review the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
Properly set up Ingress with TLS
Protect node metadata and endpoints
Verify platform binaries before deploying

Cluster Hardening15%

Use Role Based Access Controls to minimize exposure
Exercise caution in using service accounts e.g. disable defaults, minimize permissions on newly created ones
Restrict access to Kubernetes API
Upgrade Kubernetes to avoid vulnerabilities

System Hardening10%

Minimize host OS footprint (reduce attack surface)
Using least-privilege identity and access management
Minimize external access to the network
Appropriately use kernel hardening tools such as AppArmor, seccomp

Minimize Microservice Vulnerabilities20%

Use appropriate pod security standards
Manage Kubernetes secrets
Understand and implement isolation techniques (multi-tenancy, sandboxed containers, etc.)
Implement Pod-to-Pod encryption using Cilium

Supply Chain Security20%

Minimize base image footprint
Understand your supply chain (e.g. SBOM, CI/CD, artifact repositories)
Secure your supply chain (permitted registries, sign and validate artifacts, etc.)
Perform static analysis of user workloads and container images (e.g. Kubesec, KubeLinter)

Monitoring, Logging and Runtime Security20%

Perform behavioral analytics to detect malicious activities
Detect threats within physical infrastructure, apps, networks, data, users and workloads
Investigate and identify phases of attack and bad actors within the environment
Ensure immutability of containers at runtime
Use Kubernetes audit logs to monitor access
