The Central Authentication Service (CAS) is a key component of the Google Club Unified Access System (UAS), responsible for handling authentication through JWT (JSON Web Token) tokens and ensuring secure token-based user access across the Google Club ecosystem. By managing authentication in a centralized and efficient manner, CAS simplifies and secures user interactions with Google Club services.
- Token Generation: Provides a secure JWT token for user authentication.
- Token Verification: Verifies JWT tokens to ensure users are authenticated and authorized to access resources.
- Cached Authorities: Quickly retrieves and verifies user authorities for low-latency authentication and minimizes database load through caching.
- Authority Caching: Stores user authorities to optimize performance and reduce database queries.
- Cache Control: Allows for selective clearing of cached data for individual accounts or all accounts, providing flexible cache management.
The CAS is built with Express.js, a lightweight and efficient framework ideal for handling high-performance authentication tasks in a centralized system. By leveraging this technology, CAS offers responsive authentication and supports seamless integration with other UAS components.
GET /health-check: Performs a health check for the CAS service, ensuring it is running and responsive.
GET /get-all-accounts-ids-in-cache: Retrieves all cached account IDs.GET /get-account-cached-authorities: Retrieves cached authorities for a specific account.DELETE /clear-all-accounts-cache: Clears the cache for all accounts, refreshing stored authorities.DELETE /clear-account-cache: Clears the cache for a specific account, allowing updated authorities to be retrieved on the next access.
POST /generate-jwt-token: Generates a JWT token for user login.GET /get-authorities: Retrieves the authorities assigned to an account.GET /verify-token: Verifies the validity of a JWT token, confirming user authentication status.
The CAS communicates seamlessly with other components within the UAS, particularly the Identity Control Service (ICS) and the Accounts Database. This integration supports real-time updates, allowing CAS to serve as the authentication backbone for all Google Club services and ensuring a secure, scalable environment.
CAS is an integral part of the UAS architecture:
- Provides a centralized solution for authentication across the Google Club ecosystem.
- Enhances security and performance through JWT tokens and caching mechanisms.
- Reduces redundant authentication logic across applications, allowing developers to focus on core features.
- Wassim Rached is responsible for overseeing the development and management of the CAS component within the Google Club UAS.
The Central Authentication Service (CAS) offers a secure and scalable solution for authentication across Google Club applications, facilitating efficient and consistent access management within the UAS ecosystem.
