Course Outline


Cluster Setup

  • 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 objects with security control
  • Protect node metadata and endpoints
  • Minimize use of, and access to, GUI elements
  • Verify platform binaries before deploying

Cluster Hardening

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

System Hardening

  • Minimize host OS footprint (reduce attack surface)
  • Minimize IAM roles
  • Minimize external access to the network
  • Appropriately use kernel hardening tools such as AppArmor, seccomp

Minimize Microservice Vulnerabilities

  • Setup appropriate OS level security domains e.g. using PSP, OPA, security contexts
  • Manage kubernetes secrets
  • Use container runtime sandboxes in multi-tenant environments (e.g. gvisor, kata containers)
  • Implement pod to pod encryption by use of mTLS

Supply Chain Security

  • Minimize base image footprint
  • Secure your supply chain: whitelist allowed image registries, sign and validate images
  • Use static analysis of user workloads (e.g. kubernetes resources, docker files)
  • Scan images for known vulnerabilities

Monitoring, Logging and Runtime Security

  • Perform behavioral analytics of syscall process and file activities at the host and container level to detect malicious activities
  • Detect threats within physical infrastructure, apps, networks, data, users and workloads
  • Detect all phases of attack regardless where it occurs and how it spreads
  • Perform deep analytical investigation and identification of bad actors within environment
  • Ensure immutability of containers at runtime
  • Use Audit Logs to monitor access

Summary and Conclusion


  • CKA (Certified Kubernates Administrator) certification


  • Kubernetes practitioners
