Course Outline
Cluster Setup
- Implement Network security policies to limit cluster-level access
- Leverage the CIS benchmark to audit the security configurations of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects with robust security controls
- Safeguard node metadata and endpoints
- Reduce reliance on and access to GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Limit access to the Kubernetes API
- Apply Role Based Access Controls to reduce exposure
- Manage service accounts with caution, such as disabling defaults and restricting permissions on new accounts
- Keep Kubernetes updated regularly
System Hardening
- Reduce the host OS footprint to minimize the attack surface
- Limit IAM roles
- Restrict external network access
- Utilize kernel hardening tools effectively, such as AppArmor and seccomp
Minimize Microservice Vulnerabilities
- Establish appropriate OS-level security domains using tools like PSP, OPA, and security contexts
- Manage Kubernetes secrets securely
- Employ container runtime sandboxes in multi-tenant settings (e.g., gvisor, kata containers)
- Enable pod-to-pod encryption via mTLS
Supply Chain Security
- Optimize base image size
- Secure the supply chain by whitelisting authorized image registries, and signing and validating images
- Conduct static analysis on user workloads (e.g., Kubernetes resources, docker files)
- Scan images for known vulnerabilities
Monitoring, Logging and Runtime Security
- Analyze syscall processes and file activities at both host and container levels to identify malicious behavior
- Detect threats across physical infrastructure, applications, networks, data, users, and workloads
- Identify attack phases regardless of their origin or propagation method
- Conduct in-depth investigations to identify malicious actors within the environment
- Guarantee container immutability during runtime
- Utilize Audit Logs for access monitoring
Requirements
- CKA (Certified Kubernetes Administrator) certification
Target Audience
- Kubernetes practitioners
