Secure API Gateways and Token Management in Modern Microservice Ecosystems
Keywords:
API Gateway, OAuth2, JWT, Microservices, Token Management, Secure Authentication.Abstract
Microservice architectures have influenced software development by making it scalable and structured, though they also raise many security issues. The nature of microservices which is always changing and spread throughout the system, creates many difficulties for authentication and authorization security. API gateways are key agents that validate access by using authentication tokens like OAuth2 and JSON Web Tokens (JWT). An advanced plan for safe API gateway transactions is explained here, focusing on using tokens and following OAuth2 standards and JWT token rules. We examine the issuance, validation, refreshing and revocation of tokens and describe how gateways implement security effectively in support of growth and ability to overcome errors. In addition, the document covers the best ways to protect tokens, secure how they are transferred and monitor their security. The suggested model and the security considerations make a sound framework to help microservices face regular threats and vulnerabilities.
