Certified Kubernetes Security Specialist (CKS)

OSS colleagues, the Certified Kubernetes Security Specialist (CKS) program provides assurance that a CKS has the skills, knowledge, and competence on a broad range of best practices for securing container-based applications and Kubernetes platforms during build, deployment and runtime. Training modules address: 1) Cluster Setup (10%) - Use Network security policies to restrict cluster level access, Use CIS benchmark to review the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi), 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, 2) Cluster Hardening (15%) - 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, 3) System Hardening (15%) - Minimize host OS footprint (reduce attack surface), Minimize IAM roles, Minimize external access to the network, Use kernel hardening tools such as AppArmor, seccomp, 4) Minimize Microservice Vulnerabilities (20%) - Setup appropriate OS level security domains, 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, 5) Supply Chain Security (20%) - Minimize base image footprint, Secure your supply chain: whitelist allowed registries, sign and validate images, Use static analysis of user workloads (e.g.Kubernetes resources, Docker files), Scan images for known vulnerabilities, and 6) Monitoring, Logging and Runtime Security (20%) - 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, and Use Audit Logs to monitor access.
