Course Outline
Cluster Setup
- Utilise Network security policies to restrict cluster-level access
- Apply the CIS benchmark to review the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects with appropriate security controls
- Safeguard node metadata and endpoints
- Limit 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 Controls to minimise exposure
- Exercise caution with service accounts, for example by disabling defaults and minimising permissions on newly created ones
- Keep Kubernetes up to date regularly
System Hardening
- Reduce the host OS footprint to shrink the attack surface
- Minimise IAM roles
- Limit external access to the network
- Apply kernel hardening tools appropriately, such as AppArmor and seccomp
Minimising Microservice Vulnerabilities
- Establish appropriate OS-level security domains, for example using PSP, OPA, or security contexts
- Manage Kubernetes secrets effectively
- Employ container runtime sandboxes in multi-tenant environments (e.g., gvisor, kata containers)
- Implement pod-to-pod encryption using mTLS
Supply Chain Security
- Reduce the base image footprint
- Secure your supply chain by whitelisting allowed image registries and signing and validating images
- Conduct static analysis of user workloads (e.g., Kubernetes resources, Dockerfiles)
- Scan images for known vulnerabilities
Monitoring, Logging, and Runtime Security
- Perform behavioural analytics on syscall processes and file activities at both the host and container levels to detect malicious behaviour
- Identify threats across physical infrastructure, applications, networks, data, users, and workloads
- Detect all phases of an attack, regardless of its origin or propagation method
- Conduct deep analytical investigations to identify malicious actors within the environment
- Ensure the immutability of containers during runtime
- Leverage Audit Logs to monitor access
Requirements
- CKA (Certified Kubernetes Administrator) certification
