Course Outline
Introduction
Cluster Setup
- Use network security policies to restrict cluster-level access
- Use the CIS benchmark 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
- Minimise the use of and access to GUI elements
- Verify platform binaries before deployment
Cluster Hardening
- Restrict access to the Kubernetes API
- Use Role-Based Access Controls (RBAC) to minimise exposure
- Exercise caution when using service accounts (e.g., disable defaults, minimise permissions on newly created accounts)
- Update Kubernetes frequently
System Hardening
- Minimise the host OS footprint (reduce attack surface)
- Minimise IAM roles
- Minimise external network access
- Appropriately utilise kernel hardening tools such as AppArmor and seccomp
Minimise Microservice Vulnerabilities
- Set up appropriate OS-level security domains (e.g., using PSP, OPA, security contexts)
- Manage Kubernetes secrets
- Use container runtime sandboxes in multi-tenant environments (e.g., gVisor, Kata Containers)
- Implement pod-to-pod encryption using mTLS
Supply Chain Security
- Minimise the base image footprint
- Secure your supply chain: whitelist allowed image registries, sign and validate images
- Use static analysis of user workloads (e.g., Kubernetes resources, Dockerfiles)
- Scan images for known vulnerabilities
Monitoring, Logging, and Runtime Security
- Perform behavioural analytics of syscall, process, and file activities at both 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 where it occurs or how it spreads
- Conduct deep analytical investigations and identify bad actors within the environment
- Ensure container immutability at runtime
- Use audit logs to monitor access
