Course Outline
Cluster Setup
- Implement Network security policies to control access at the cluster level
- Utilize 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
- Limit the use of and access to GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Control access to the Kubernetes API
- Apply Role-Based Access Controls to minimize security exposure
- Exercise caution with service accounts by disabling defaults and restricting permissions on newly created accounts
- Maintain frequent updates for Kubernetes
System Hardening
- Reduce the host OS footprint to minimize the attack surface
- Limit IAM roles
- Restrict external network access
- Apply kernel hardening tools effectively, such as AppArmor and seccomp
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains using PSP, OPA, and security contexts
- Manage Kubernetes secrets securely
- Leverage container runtime sandboxes in multi-tenant settings (e.g., gvisor, kata containers)
- Enforce pod-to-pod encryption via mTLS
Supply Chain Security
- Optimize the base image footprint
- Protect the supply chain by whitelisting image registries and signing/validating images
- Conduct static analysis of user workloads (e.g., Kubernetes resources, Dockerfiles)
- Scan images for known vulnerabilities
Monitoring, Logging, and Runtime Security
- Analyze syscall processes and file activities at the host and container levels to identify malicious behavior
- Identify threats across physical infrastructure, applications, networks, data, users, and workloads
- Detect attack phases regardless of location or propagation method
- Conduct deep analytical investigations to identify malicious actors within the environment
- Maintain container immutability during runtime
- Utilize Audit Logs to monitor access patterns
