Course Outline
Cluster Setup
- Apply Network security policies to limit cluster-level access
- Leverage the CIS benchmark to assess the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects with appropriate security controls
- Safeguard node metadata and endpoints
- Reduce the usage of and access to GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Limit access to the Kubernetes API
- Implement Role-Based Access Control to reduce exposure
- Exercise caution with service accounts, such as disabling defaults and minimizing permissions for new accounts
- Keep Kubernetes up to date with frequent updates
System Hardening
- Reduce the host OS footprint to minimize the attack surface
- Limit the scope of IAM roles
- Restrict external network access
- Utilize kernel hardening tools like AppArmor and seccomp effectively
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains using PSP, OPA, or security contexts
- Manage Kubernetes secrets securely
- Employ container runtime sandboxes in multi-tenant settings (e.g., gvisor, kata containers)
- Enforce pod-to-pod encryption via mTLS
Supply Chain Security
- Keep base image footprints minimal
- Secure the supply chain by whitelisting allowed image registries and signing/validating images
- Perform static analysis on user workloads (e.g., Kubernetes resources, Dockerfiles)
- Scan images for known vulnerabilities
Monitoring, Logging, and Runtime Security
- Conduct behavioral analytics on system call processes and file activities at both host and container levels to identify malicious behavior
- Identify threats across physical infrastructure, applications, networks, data, users, and workloads
- Detect all phases of an attack, regardless of origin or spread
- Carry out deep analytical investigations to identify malicious actors within the environment
- Ensure the immutability of containers during runtime
- Utilize Audit Logs to track and monitor access
