Course Outline
Cluster Setup
- Implement Network security policies to restrict cluster-level access
- Utilize the CIS benchmark to review the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects appropriately with 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
- Employ Role Based Access Controls to minimize exposure
- Exercise caution with service accounts, for instance by disabling defaults and minimizing permissions on newly created ones
- Keep Kubernetes up to date through frequent updates
System Hardening
- Minimize the host OS footprint to reduce the attack surface
- Optimize IAM roles to be as minimal as necessary
- 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 such as PSP, OPA, and security contexts
- Manage Kubernetes secrets effectively
- Leverage 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 the supply chain by whitelisting allowed image registries, and signing and 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 of syscall processes and file activities at both the host and container levels to identify 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 path
- Perform deep analytical investigations to identify and isolate bad actors within the environment
- Ensure the immutability of containers during runtime
- Utilize Audit Logs to monitor access patterns
