What is Authentication and Authorization in microservices
In the context of microservices, authentication and authorization are two crucial components for ensuring the security of the system. Here’s a breakdown of each:
1. What is Authentication in Microservices?
Authentication is the process of verifying the identity of a user or service. In a microservices architecture, each service might need to authenticate itself to other services or authenticate users who are accessing the system.
- This process typically involves presenting credentials, such as usernames and passwords, API keys, or tokens, to prove identity.
- Common authentication mechanisms in microservices include JSON Web Tokens (JWT), OAuth, and OpenID Connect.
2. What is Authorization in Microservices?
Authorization, on the other hand, is the process of determining what actions an authenticated user or service is allowed to perform. Once a user or service is authenticated, authorization mechanisms enforce access control policies to ensure that only authorized actions are permitted.
- This often involves defining roles and permissions, which are then used to make access control decisions.
- Authorization mechanisms can range from simple role-based access control (RBAC) to more fine-grained access control strategies like attribute-based access control (ABAC) or policy-based access control (PBAC).
