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
- 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
- Apply Role-Based Access Controls to reduce exposure
- Exercise caution when using service accounts, such as disabling defaults and minimizing permissions on newly created ones
- Apply Kubernetes updates regularly
System Hardening
- Reduce the host OS footprint to lower the attack surface
- Limit IAM roles
- 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 instance using PSP, OPA, or security contexts
- Manage Kubernetes secrets effectively
- Employ container runtime sandboxes in multi-tenant settings (e.g., gvisor, kata containers)
- Enforce pod-to-pod encryption using mTLS
Supply Chain Security
- Reduce the base image footprint
- Secure the supply chain by whitelisting authorized image registries and signing and validating images
- Perform static analysis on user workloads (e.g., Kubernetes resources, docker files)
- Scan images for known vulnerabilities
Monitoring, Logging, and Runtime Security
- Conduct behavioral analytics of system call processes and file activities at both host and container levels to identify malicious actions
- 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
- Guarantee container immutability during runtime
- Utilize Audit Logs to track access
Requirements
- CKA (Certified Kubernetes Administrator) certification
Target Audience
- Kubernetes practitioners
