Course Outline
Cluster Setup
- Implement Network security policies to limit cluster-level access
- Apply CIS benchmarks to review the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects with appropriate security controls
- Safeguard node metadata and endpoints
- Reduce reliance on and access to GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Limit access to the Kubernetes API
- Leverage Role Based Access Controls to minimize exposure
- Handle service accounts with caution, such as disabling defaults and restricting permissions on new accounts
- Maintain frequent Kubernetes updates
System Hardening
- Reduce the host OS footprint to lower the attack surface
- Limit IAM roles
- Restrict external network access
- Utilize kernel hardening tools like AppArmor and seccomp effectively
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains using PSP, OPA, or security contexts
- Manage Kubernetes secrets securely
- Employ container runtime sandboxes in multi-tenant settings (e.g., gvisor, kata containers)
- Enable pod-to-pod encryption via mTLS
Supply Chain Security
- Reduce the footprint of base images
- Protect the supply chain by whitelisting image registries and signing and validating images
- Apply static analysis to user workloads (e.g., Kubernetes resources, Dockerfiles)
- Scan images for identified vulnerabilities
Monitoring, Logging, and Runtime Security
- Analyze syscall processes and file activities at both host and container levels to identify malicious behavior
- Identify threats across physical infrastructure, applications, networks, data, users, and workloads
- Detect all stages of attacks, regardless of their origin or propagation method
- Conduct in-depth investigations to identify malicious actors within the environment
- Guarantee container immutability during runtime
- Utilize Audit Logs to track access
Requirements
- CKA (Certified Kubernetes Administrator) certification
Target Audience
