Course Outline
Cluster Setup
- Implement Network security policies to limit cluster-level access
- Leverage the CIS benchmark to audit the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects with appropriate security controls
- Safeguard node metadata and endpoints
- Limit the usage and access of GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Control access to the Kubernetes API
- Apply Role Based Access Controls to reduce exposure
- Handle service accounts with care, such as disabling defaults and minimizing permissions for new accounts
- Keep Kubernetes up to date through frequent updates
System Hardening
- Reduce the host OS footprint to lower the attack surface
- Streamline IAM roles
- Limit external network access
- Utilize kernel hardening tools like AppArmor and seccomp effectively
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains using tools like PSP, OPA, and security contexts
- Oversee Kubernetes secrets management
- Employ container runtime sandboxes in multi-tenant settings (e.g., gvisor, kata containers)
- Enforce pod-to-pod encryption via mTLS
Supply Chain Security
- Reduce the size of base images
- Secure the supply chain by whitelisting allowed image registries and signing/validating images
- Apply static analysis to user workloads (e.g., Kubernetes resources, Dockerfiles)
- Scan images for existing vulnerabilities
Monitoring, Logging, and Runtime Security
- Conduct behavioral analytics of syscall processes and file activities at both host and container levels to identify malicious actions
- Identify threats across physical infrastructure, applications, networks, data, users, and workloads
- Monitor all phases of attacks regardless of origin or propagation path
- Carry out in-depth analysis to identify malicious actors within the environment
- Maintain container immutability during runtime
- Utilize Audit Logs to track access events
Requirements
- CKA (Certified Kubernetes Administrator) certification
Audience
- Professionals practicing Kubernetes
