Who Should Attend

  • Professionals with CKA certification or equivalent experience seeking to specialize in securing Kubernetes clusters and infrastructure.
  • DevOps practitioners aiming to enhance their skills in implementing security best practices for cloud-native applications and Kubernetes environments.
  • IT security specialists looking to deepen their expertise in protecting Kubernetes-based systems and ensuring compliance in enterprise settings.
  • Individuals pursuing the Certified Kubernetes Security Specialist (CKS) exam who need advanced, hands-on training to master Kubernetes security concepts and succeed in certification.

Prerequisites

  • Must hold a valid CKA certification or equivalent experience in managing Kubernetes clusters, as required by the Linux Foundation for CKS eligibility.
  • Proficiency in Kubernetes concepts, including cluster architecture, networking, storage, and workload management, to effectively engage with advanced security topics.
  • Familiarity with IT security principles, such as encryption, access control, and network security, to build upon during the course.
  • A suitable system (physical or virtual) to practice labs, with tools like kubectl, Docker, and a Kubernetes cluster (e.g., Minikube or cloud-based) installed.

Course Content

Kubernetes Security Fundamentals
  • Understand the shared responsibility model for securing Kubernetes in on-premises and cloud environments.
  • Explore the CKS exam domains, including cluster hardening, supply chain security, and runtime protection.
  • Identify common Kubernetes security threats, such as privilege escalation and misconfigured APIs.
  • Learn Kubernetes security best practices as outlined by CNCF and NSA/CISA guidelines.
Cluster Setup and Hardening
  • Configure secure Kubernetes cluster installation using kubeadm with TLS and secure API settings.
  • Harden control plane components, including API server, controller manager, and scheduler, to reduce attack surfaces.
  • Implement secure etcd configurations, including encryption at rest and access controls.
  • Verify cluster compliance with CIS Kubernetes Benchmark using tools like kube-bench.
Role-Based Access Control (RBAC)
  • Design and implement RBAC policies to restrict user and service account permissions in Kubernetes.
  • Create roles and cluster roles to enforce least privilege for specific namespaces and resources.
  • Bind roles to users, groups, or service accounts using role bindings and cluster role bindings.
  • Troubleshoot RBAC issues, such as unauthorized access or overly permissive policies.
Network Security and Policies
  • Configure network policies to control pod-to-pod and external traffic, restricting unauthorized communication.
  • Implement CNI plugins (e.g., Calico, Cilium) to support advanced network security features.
  • Secure Ingress controllers and services to prevent exposure of sensitive endpoints.
  • Audit and troubleshoot network policy enforcement using tools like kubectl and network diagnostics.
Pod and Container Security
  • Define Pod Security Standards (PSS) to enforce security baselines, such as preventing privileged containers.
  • Configure security contexts for pods and containers to limit privileges, users, and capabilities.
  • Use AppArmor or Seccomp profiles to restrict system calls and enhance container isolation.
  • Mitigate container vulnerabilities by scanning images and enforcing runtime security policies.
Securing the Software Supply Chain
  • Implement image signing and verification using tools like cosign to ensure trusted container images.
  • Configure admission controllers, such as Open Policy Agent (OPA), to enforce image security policies.
  • Scan container images for vulnerabilities using tools like Trivy or Clair during CI/CD pipelines.
  • Harden container registries to prevent unauthorized access and ensure image integrity.
Kubernetes API Security
  • Secure the Kubernetes API server with authentication mechanisms, including certificates and tokens.
  • Enable audit logging to track API requests and detect suspicious activities.
  • Restrict anonymous access and enforce mutual TLS (mTLS) for API communication.
  • Troubleshoot API security issues, such as authentication failures or misconfigured access controls.
Monitoring and Logging for Security
  • Configure centralized logging with tools like Fluentd or Loki to collect and analyze security events.
  • Set up Prometheus and Grafana to monitor cluster security metrics, such as unauthorized access attempts.
  • Implement runtime security monitoring using tools like Falco to detect anomalous behavior.
  • Analyze logs and alerts to respond to security incidents and perform forensic investigations.
Cluster Backup and Recovery
  • Back up critical cluster data, including etcd snapshots, to ensure recovery from security breaches.
  • Configure secure backup storage with encryption and access controls for sensitive data.
  • Practice restoring clusters from backups to minimize downtime during security incidents.
  • Troubleshoot backup and recovery issues, such as corrupted snapshots or access errors.
CKS Exam Preparation
  • Review the CKS exam structure, including performance-based tasks, time constraints, and scoring criteria.
  • Practice hands-on labs simulating exam scenarios, such as securing clusters and mitigating vulnerabilities.
  • Master kubectl commands and security tools (e.g., kube-bench, Trivy) required for exam tasks.
  • Develop troubleshooting and time-management strategies to address complex security challenges efficiently.
