Course Outline
Introduction
Cluster Setup
- Use Network Security Policies to restrict cluster-level access.
- Use CIS benchmarks to review the security configuration of Kubernetes components (etcd, kubelet, kube-dns, kube-apiserver).
- Properly configure Ingress objects with 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 Control (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
- Minimize the host OS footprint (reduce the attack surface).
- Minimize IAM roles.
- Minimize external access to the network.
- Appropriately utilize kernel hardening tools such as AppArmor and seccomp.
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains (e.g., using Pod Security Standards, 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
- Minimize base image footprint.
- Secure the supply chain: whitelist allowed image registries, and sign and validate images.
- Perform static analysis of 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.
- Detect all phases of an attack regardless of its origin or propagation method.
- Perform deep analytical investigations to identify bad actors within the environment.
- Ensure the immutability of containers at runtime.
- Use Audit Logs to monitor access.
