The objective of this project is to design and implement a Secure API Authentication System using the OAuth 2.0 framework. The system ensures secure access to APIs through token-based authorization, protecting sensitive resources while helping students understand modern API security standards and authentication protocols.
Study API security challenges and the fundamentals of OAuth 2.0 framework.
Analyze OAuth components such as Resource Owner, Client, Authorization Server, and Resource Server.
Prepare Software Requirement Specification (SRS) and authentication flow documentation.
Design system architecture including authorization server and protected API endpoints.
Create database schema for users, client applications, access tokens, refresh tokens, and logs.
Implement secure user authentication with password hashing techniques.
Develop OAuth 2.0 authorization flow (Authorization Code Grant simulation).
Generate and validate access tokens using JWT or secure token mechanisms.
Implement token expiration and refresh token functionality.
Secure API endpoints by validating tokens before granting access.
Apply role-based access control for API-level permissions.
Maintain logs of API requests and authentication events.
Protect against common API threats such as token replay and unauthorized access.
Perform unit testing, integration testing, and token validation testing.
Prepare documentation including OAuth flow diagrams, ER diagrams, API documentation, and test cases.
Deploy system locally or on a cloud platform for demonstration.
