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).
- Properly configure Ingress objects with robust 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 regularly.
System Hardening
- Reduce the host OS footprint to minimize the attack surface.
- Minimize IAM roles.
- Limit external network access.
- Appropriately utilize kernel hardening tools such as AppArmor and seccomp.
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains, e.g., using PSP, OPA, and security contexts.
- Manage Kubernetes secrets effectively.
- Employ container runtime sandboxes in multi-tenant environments (e.g., gvisor, Kata Containers).
- Implement pod-to-pod encryption using mTLS.
Supply Chain Security
- Minimize the base image footprint.
- Secure your supply chain: whitelist allowed image registries, and sign and validate images.
- Conduct static analysis of user workloads (e.g., Kubernetes resources, Docker files).
- Scan images for known vulnerabilities.
Monitoring, Logging, and Runtime Security
- Perform behavioral analytics of syscall processes and file activities at the host and container levels to detect malicious activities.
- Identify threats within physical infrastructure, applications, networks, data, users, and workloads.
- Detect all phases of an attack, regardless of its origin and propagation path.
- Conduct deep analytical investigations to identify bad actors within the environment.
- Ensure the immutability of containers at runtime.
- Use Audit Logs to monitor access.
