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.

What are the key components discussed for securing REST APIs in a microservices architecture?

• Authentication, Authorization, JWT tokens, Role-based access control

• Encryption, Decryption, SSL certificates, Firewalls

• Load balancing, Caching, Data replication, Backup

• Data mining, Machine learning, AI algorithms, Neural networks

What is the primary role of the auth server in the security flow?

• To encrypt data

• To store user data

• To generate and verify tokens

• To manage network traffic

How does the resource server ensure that a token is not tampered with?

• By verifying the token with the auth server

• By using a firewall

• By storing the token in a database

• By encrypting the token

What is the significance of a JWT token in the security process?

• It encrypts the data

• It holds authorization information for accessing APIs

• It manages user sessions

• It provides a secure way to store passwords

What will the next video focus on regarding JWT tokens?

• The history of JWT tokens

• The disadvantages of JWT tokens

• The comparison between JWT and OAuth

• The various ways to generate JWT tokens
