The objective of this project is to design and implement a Secure Single Sign-On (SSO) Authentication System that allows users to access multiple applications using a single set of credentials. The system enhances security, reduces repeated logins, and introduces students to centralized authentication and session management concepts.
Study authentication challenges in multi-application environments and SSO concepts.
Analyze SSO standards such as token-based authentication and centralized identity management.
Prepare Software Requirement Specification (SRS) and system workflow documentation.
Design system architecture including authentication server, client applications, and token validation mechanism.
Create database schema for users, applications, authentication tokens, sessions, and login logs.
Implement secure user registration and login with password hashing techniques.
Develop centralized authentication server to issue secure tokens after successful login.
Implement token-based session management (JWT or session IDs).
Integrate multiple applications that validate user identity using the issued SSO token.
Implement token expiration and logout functionality across all connected applications.
Apply role-based access control for application-level permissions.
Secure communication between applications and authentication server.
Maintain audit logs for login activities and token usage.
Perform unit testing, integration testing, and authentication flow testing.
Validate protection against common attacks such as token replay and session hijacking.
Prepare project documentation including ER diagrams, SSO flowcharts, test cases, and deployment steps.
Deploy the system locally or on a cloud platform for demonstration.
