Course Outline
Cluster Setup
- Implement Network security policies to restrict cluster-level access
- Apply CIS benchmarks to review the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects correctly with appropriate security controls
- Secure node metadata and endpoints
- Minimize the usage of and access to GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Limit access to the Kubernetes API
- Leverage Role-Based Access Control (RBAC) to minimize exposure
- Exercise caution when using service accounts, such as disabling defaults and restricting permissions on newly created accounts
- Apply Kubernetes updates regularly
System Hardening
- Reduce the host OS footprint to minimize the attack surface
- Limit IAM roles
- Restrict external network access
- Utilize kernel hardening tools such as AppArmor and seccomp appropriately
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains, for example, using PSP, OPA, or security contexts
- Manage Kubernetes secrets effectively
- 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 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 analysis of syscall processes and file activities at both the host and container levels to detect malicious behavior
- Identify threats within physical infrastructure, applications, networks, data, users, and workloads
- Detect all phases of an attack, regardless of its origin or propagation method
- Carefully investigate and identify malicious actors within the environment
- Guarantee the immutability of containers during runtime
- Utilize Audit Logs to monitor access patterns
Requirements
- CKA (Certified Kubernetes Administrator) certification
Target Audience
- Kubernetes practitioners
