Kubernetes IAM and RBAC Fundamentals

Securing containerized applications requires a deep understanding of who can access your cluster and what actions they can perform. Without proper access controls, even the most robust Kubernetes deployments remain vulnerable to security breaches. This text-based course guides you through the core principles of Kubernetes Identity and Access Management (IAM). You will learn how to transition from basic configurations to secure, production-ready access architectures using clear written explanations, step-by-step configuration walk-throughs, and practical policy examples. What you'll learn: Understand foundational Kubernetes security terminology, API access phases, and authentication mechanisms; Configure Role-Based Access Control (RBAC) using Roles, ClusterRoles, RoleBindings, and ClusterRoleBindings; Integrate external identity providers using modern OpenID Connect (OIDC) protocols; Implement zero-trust security principles and the strategy of least privilege for cluster users and service accounts; Manage secure remote access guidelines, SSH policies, and multi-factor authentication concepts; Apply modern service account token volume projection for secure workload identity. The course starts with essential terminology and the basics of the Kubernetes API security model before moving into practical RBAC configurations and external identity integration. You will study clear text-based scenarios and configuration files to build a secure access environment. This course is designed for system administrators, DevOps beginners, and security enthusiasts who want to understand Kubernetes access control. No prior experience with Kubernetes security is required, though a basic familiarity with container concepts is helpful.
