Course Outline
Introduction
Cluster Setup
- Utilize network security policies to restrict 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
- Protect node metadata and endpoints
- Minimize the use of and access to GUI elements
- Verify platform binaries before deployment
Cluster Hardening
- Restrict access to the Kubernetes API
- Implement Role-Based Access Controls (RBAC) to minimize exposure
- Exercise caution when using service accounts: disable defaults and minimize permissions on newly created ones
- Keep Kubernetes updated frequently
System Hardening
- Reduce the host OS footprint to minimize the attack surface
- Minimize IAM roles
- Limit external access to the network
- Appropriately utilize kernel hardening tools such as AppArmor and seccomp
Minimize Microservice Vulnerabilities
- Establish appropriate OS-level security domains (e.g., using PSP, OPA, security contexts)
- Manage Kubernetes secrets effectively
- Use container runtime sandboxes in multi-tenant environments (e.g., gvisor, kata containers)
- Implement pod-to-pod encryption using mTLS
Supply Chain Security
- Reduce the footprint of base images
- Secure the supply chain: whitelist allowed image registries, and sign and validate images
- Perform static analysis on user workloads (e.g., Kubernetes resources, Dockerfiles)
- Scan images for known vulnerabilities
Monitoring, Logging, and Runtime Security
- Conduct behavioral analytics of syscall processes and file activities at the host and container levels to detect malicious activities
- Detect threats within physical infrastructure, applications, networks, data, users, and workloads
- Identify all phases of an attack regardless of origin or propagation path
- Perform deep analytical investigations to identify bad actors within the environment
- Ensure the immutability of containers at runtime
- Use Audit Logs to monitor access
