Internship: Single Sign-On
Budget: $TBD

Technologies: Networking, OAuth

Problem Statement:

Implement Single Sign-On (SSO) functionality to seamlessly authenticate and authorize users from a source environment to access a destination environment and its associated systems without the need for multiple login credentials.

Key Elements:

Identity Provider (IdP): Develop an Identity Provider component in the source environment responsible for authenticating users and generating authentication tokens.

SSO Integration in Source System: Integrate SSO capabilities into the source system's login process. When a user logs in, the system should communicate with the IdP to obtain an authentication token.

Authentication Token: Utilize industry-standard authentication protocols (e.g., OAuth, OpenID Connect) to generate and validate authentication tokens. The token should contain information about the user's identity and authentication status.

Token Exchange Mechanism: Implement a secure token exchange mechanism that allows the source environment to securely exchange user authentication tokens with the destination environment.

Destination Environment Integration: Integrate the destination environment with the SSO system to validate incoming authentication tokens and extract user identity information.

User Attributes and Permissions: Ensure that the SSO process includes user attributes and permissions, allowing the destination environment to determine the user's access rights and roles.

Session Management: Implement session management to maintain a consistent user session across both environments. The user should not be required to re-authenticate when moving from the source to the destination environment.

User Logout Handling: Implement a mechanism for handling user logout across both environments to ensure proper termination of sessions and secure user access.

Expected Outcome:

The expected outcome of this SSO implementation is a seamless and secure authentication and authorization process that allows a user logged into the source environment to access the destination environment and its associated systems without the need for additional login credentials.

Effortless User Experience: Users experience a seamless transition between the source and destination environments without the need for repeated logins.

Reduced Password Fatigue: Users are relieved from the burden of managing multiple sets of login credentials, reducing password fatigue.

Enhanced Security: Security is improved through the use of industry-standard authentication protocols, secure token exchange mechanisms, and consistent session management.

Centralized Identity Management: Centralized identity management ensures that user attributes and permissions are accurately maintained across both environments.

Technologies Used:

Identity Provider Technologies: Use Identity Provider technologies such as Keycloak, Okta, Auth0, or custom-built solutions.

Authentication Protocols: Implement widely adopted authentication protocols such as OAuth 2.0 and OpenID Connect.

Token Exchange Mechanism: Develop a secure token exchange mechanism, leveraging standards like OAuth token exchange.

Session Management: Use session management techniques and technologies to maintain a consistent user session.

Destination Environment Integration: Integrate the destination environment with the SSO system using compatible libraries and protocols.

Other Considerations:

Security Auditing: Implement security auditing mechanisms to monitor and audit SSO-related activities for security compliance.

User Notifications: Provide user notifications and feedback to inform them about the SSO process, such as successful login, session termination, etc.

Error Handling: Implement robust error handling mechanisms to gracefully manage scenarios where SSO processes may encounter issues.
