Course Outline
Cluster Setup
- Implement network security policies to restrict cluster-level access.
- Utilize CIS benchmarks to review the security configurations of Kubernetes components (etcd, kubelet, kubedns, kubeapi).
- Configure Ingress objects with appropriate security controls.
- Safeguard node metadata and endpoints.
- Limit the usage of, and access to, GUI elements.
- Validate platform binaries prior to deployment.
Cluster Hardening
- Restrict access to the Kubernetes API.
- Employ Role-Based Access Control (RBAC) to minimize exposure.
- Exercise caution with service accounts, such as disabling defaults and minimizing permissions for newly created ones.
- Maintain frequent updates to Kubernetes.
System Hardening
- Reduce the host OS footprint to minimize the attack surface.
- Minimize IAM roles.
- Limit external access to the network.
- Apply kernel hardening tools, such as AppArmor and seccomp, appropriately.
Minimize Microservice Vulnerabilities
- Establish appropriate OS-level security domains using tools like PSP, 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
- Reduce the footprint of base images.
- Secure the supply chain by whitelisting approved image registries and signing/validating images.
- Apply static analysis to user workloads (e.g., Kubernetes resources, Dockerfiles).
- Scan images for known vulnerabilities.
Monitoring, Logging, and Runtime Security
- Conduct behavioral analytics on syscall processes and file activities at both host and container levels to detect malicious actions.
- Identify threats across physical infrastructure, applications, networks, data, users, and workloads.
- Detect all phases of attacks, regardless of origin or propagation method.
- Perform deep analytical investigations to identify malicious actors within the environment.
- Ensure the immutability of containers during runtime.
- Leverage Audit Logs to monitor access activities.
