Course Outline
Cluster Setup
- Apply Network security policies to limit cluster-level access
- Leverage CIS benchmarks to audit the security configuration of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects with appropriate security controls
- Secure node metadata and endpoints
- Limit the use of and access to GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Limit access to the Kubernetes API
- Implement Role Based Access Controls to reduce exposure
- Exercise caution with service accounts, such as disabling defaults and minimizing permissions for new accounts
- Keep Kubernetes up to date frequently
System Hardening
- Reduce host OS footprint to minimize the attack surface
- Minimize IAM roles
- Limit external network access
- Utilize kernel hardening tools like AppArmor and seccomp appropriately
Minimize Microservice Vulnerabilities
- Establish OS-level security domains using tools like PSP, OPA, and 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 footprint of base images
- Secure the supply chain by whitelisting allowed 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 syscall processes and file activities at the 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 propagation method
- Carry out deep analytical investigations to identify bad actors within the environment
- Guarantee container immutability during runtime
- Utilize Audit Logs to monitor access patterns
