Course Outline
Cluster Setup
- Leverage Network security policies to limit cluster-level access
- Apply the CIS benchmark to audit the security configurations of Kubernetes components (etcd, kubelet, kubedns, kubeapi)
- Configure Ingress objects with appropriate security controls
- Safeguard node metadata and endpoints
- Reduce the utilization of, and access to, GUI elements
- Validate platform binaries prior to deployment
Cluster Hardening
- Limit access to the Kubernetes API
- Employ Role-Based Access Controls to reduce exposure
- Handle service accounts with caution, such as disabling defaults and minimizing permissions for newly created accounts
- Maintain frequent updates to Kubernetes
System Hardening
- Reduce the host OS footprint to lower the attack surface
- Minimize the scope of IAM roles
- Limit external network access
- Utilize kernel hardening tools such as AppArmor and seccomp effectively
Minimizing Microservice Vulnerabilities
- Establish appropriate OS-level security domains, for example, by using PSP, OPA, or security contexts
- Manage Kubernetes secrets securely
- Utilize container runtime sandboxes in multi-tenant settings (e.g., gvisor, kata containers)
- Implement pod-to-pod encryption via mTLS
Supply Chain Security
- Minimize the size of the base image
- Protect the supply chain by whitelisting approved image registries and signing/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 behavior
- Identify threats within physical infrastructure, applications, networks, data, users, and workloads
- Detect attack phases regardless of their origin or propagation method
- Carry out deep analytical investigations to identify malicious actors within the environment
- Guarantee the immutability of containers during runtime
- Monitor access patterns using Audit Logs
