Kubernetes Security Foundations: Network Policies, CIS Benchmarks, and TLS

Kubernetes security can feel overwhelming, but securing cluster communication and configuration is essential for protecting modern application workloads. This text-based course guides you through the fundamental principles of securing containerized environments from the ground up. You will transition from basic cluster administration to implementing solid security controls, understanding how to restrict internal traffic, audit configurations against industry standards, and encrypt external access. What you'll learn: - Understand core Kubernetes security terminology and foundational concepts - Configure NetworkPolicies to restrict pod-to-pod communication using zero-trust principles - Apply CIS benchmarks to audit and secure your cluster configurations against industry standards - Implement secure Ingress controllers with TLS encryption to protect external traffic - Identify and remediate common security misconfigurations within your manifests The course begins with foundational security definitions and key concepts before guiding you through practical, text-based explanations of network policies, benchmark tools, and secure ingress setups. It is designed for system administrators, developers, and aspiring security professionals who are new to Kubernetes security and want to build a strong, practical foundation.
