Building Microservices API in Go - Securing Application

The video tutorial covers practices for securing REST APIs within a microservices architecture. It explains the roles of authentication and authorization, JWT tokens, and role-based access control. The tutorial outlines a six-step process involving a resource server and an auth server, which handles token generation and validation. The auth server, similar to OAuth, issues tokens upon successful authentication, which are then used to access APIs securely. The importance of JWT tokens in the security process is emphasized, and the next video will delve deeper into JWT token generation.
