Securing Azure Functions with Authorization Levels

When building serverless applications, securing your endpoints is just as critical as writing the code itself. Without proper access control, your APIs and backend logic remain exposed to unauthorized access and potential exploits. This text-only course guides you through the core authorization levels in Azure Functions, showing you how to control access and protect your serverless workloads. You will transition from open, unprotected endpoints to a structured, secure architecture using built-in authorization mechanisms and modern identity-based security practices. What you will learn: Understand the foundational security concepts and terminology of serverless endpoint protection; Apply anonymous authorization for public-facing endpoints that do not require credentials; Configure function-level authorization keys to restrict access to specific function endpoints; Implement admin-level authorization using host keys for global administrative access; Integrate managed identities and token-based authentication to move beyond static keys; Practice securing your development environment and managing secrets safely. The course starts with essential security definitions and terminology before walking you through step-by-step configurations for each authorization level. You will read clear explanations, analyze configuration examples, and complete conceptual exercises designed to reinforce best practices. This course is designed for beginner developers, cloud enthusiasts, and security beginners who want to understand serverless access control. No prior experience with cloud security is required.
