Course Outline
Cluster Setup
- Implement Network security policies to limit cluster-level access
- Leverage CIS benchmarks to assess the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects with appropriate security controls
- Secure node metadata and endpoints
- Limit the usage of, and access to, GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Restrict access to the Kubernetes API
- Apply Role Based Access Controls to minimize exposure
- Exercise caution with service accounts, such as disabling defaults and minimizing permissions on new accounts
- Keep Kubernetes up to date with frequent updates
System Hardening
- Reduce the host OS footprint to minimize the attack surface
- Limit IAM roles to essential functions only
- Restrict external access to the network
- Utilize kernel hardening tools like AppArmor and seccomp appropriately
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains, for example using PSP, OPA, and security contexts
- Manage Kubernetes secrets effectively
- Employ container runtime sandboxes in multi-tenant environments (e.g., gvisor, kata containers)
- Enforce pod-to-pod encryption via mTLS
Supply Chain Security
- Reduce the size of base images
- Secure the supply chain by whitelisting allowed image registries and signing and validating images
- Apply static analysis to user workloads, including kubernetes resources and docker files
- Perform vulnerability scans on images for known issues
Monitoring, Logging, and Runtime Security
- Conduct behavioral analytics on syscall processes and file activities at both the 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 propagation method
- Carry out in-depth analytical investigations to identify malicious actors within the environment
- Guarantee container immutability during runtime
- Utilize Audit Logs to oversee access activities
Requirements
- CKA (Certified Kubernates Administrator) certification
Target Audience
- Professionals working with Kubernetes
