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, kube-dns, kube-apiserver).
- Configure Ingress objects with appropriate security controls.
- Protect 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.
- Implement Role-Based Access Control (RBAC) to minimize exposure.
- Exercise caution when using service accounts: disable defaults and minimize permissions for newly created accounts.
- Keep Kubernetes updated frequently.
System Hardening
- Minimize the host OS footprint to reduce the attack surface.
- Reduce IAM roles to the necessary minimum.
- Limit external access to the network.
- Properly utilize kernel hardening tools such as AppArmor and seccomp.
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains using Pod Security Policies (PSP), Open Policy Agent (OPA), and security contexts.
- Manage Kubernetes secrets effectively.
- Utilize container runtime sandboxes in multi-tenant environments (e.g., gVisor, Kata Containers).
- Implement pod-to-pod encryption using mTLS.
Supply Chain Security
- Minimize the footprint of base images.
- Secure the supply chain by whitelisting allowed image registries and signing/validating 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.
- Identify 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 malicious actors within the environment.
- Ensure container immutability during runtime.
- Utilize Audit Logs to monitor access.
