Course Outline
Cluster Setup
- Apply network security policies to restrict access at the cluster level
- Leverage the CIS benchmark to audit 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
- Validate platform binaries prior to deployment
Cluster Hardening
- Limit access to the Kubernetes API
- Utilise Role Based Access Controls to reduce exposure
- Exercise caution when using service accounts, such as disabling defaults and minimising permissions for newly created ones
- Keep Kubernetes updated regularly
System Hardening
- Reduce the host OS footprint to minimise the attack surface
- Streamline IAM roles
- Limit external network access
- 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 securely
- 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 size of base images
- Secure the supply chain by whitelisting authorised 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 of syscall processes and file activities at both the host and container levels to identify malicious actions
- Detect threats across physical infrastructure, applications, networks, data, users, and workloads
- Identify all phases of attacks, regardless of their origin or method of propagation
- Carry out deep analytical investigations to identify and isolate bad actors within the environment
- Ensure the immutability of containers during runtime
- Utilise audit logs to monitor access
