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.
- Safeguard node metadata and endpoints.
- Minimize the use of and access to GUI elements.
- Verify platform binaries prior to deployment.
Cluster Hardening
- Restrict access to the Kubernetes API.
- Employ Role-Based Access Control (RBAC) to minimize exposure.
- Exercise caution when using service accounts, such as disabling defaults and minimizing permissions on newly created ones.
- Keep Kubernetes updated frequently.
System Hardening
- Reduce the host OS footprint to decrease the attack surface.
- Minimize IAM roles.
- Minimize external network access.
- Effectively 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 securely.
- 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 by whitelisting allowed image registries and signing/validating images.
- Conduct static analysis of user workloads (e.g., Kubernetes resources, Dockerfiles).
- 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.
- Detect threats within physical infrastructure, applications, networks, data, users, and workloads.
- Identify all phases of an attack, regardless of its origin or propagation method.
- Conduct deep analytical investigations to identify bad actors within the environment.
- Ensure container immutability at runtime.
- Utilize Audit Logs to monitor access.
