Serverless Security: Token-Based Authentication and Role Management

Modern cloud-native applications rely heavily on serverless architectures, but keeping your APIs and functions secure is a critical challenge. Understanding how to verify user identities and enforce permissions is essential for any backend developer. This text-based course guides you through the foundational concepts of modern token-based authentication. You will learn how to inspect, validate, and utilize JSON Web Tokens (JWTs) to restrict access to your serverless functions based on user roles, ensuring only authorized requests are processed. What you'll learn: - Understand the fundamentals of identity tokens, claims, and JSON Web Token structures. - Configure serverless functions to extract and validate incoming authentication tokens. - Implement role-based access control to restrict function execution to specific user groups. - Apply modern security practices like signature validation using JSON Web Key Sets. - Manage and update user roles securely within your identity provider workflow. - Debug and test secured serverless endpoints using mock tokens in written exercises. The course begins with the core terminology of authentication and identity management before moving into step-by-step written guides on writing secure function code and verifying user permissions. This program is designed for beginning backend developers, cloud enthusiasts, and web developers looking to secure their serverless APIs, with no prior security experience required.
