Securing Utility Ecosystems: Centralized Authentication & Authorization Server
Project Summary
The Authentication & Authorization Server, branded as MTNID, was developed as a microservice REST API application that acts as the central identity provider for Utility sector operations. It issues secure authentication tokens to microservices, applications, and third-party systems, ensuring unified identity management across diverse environments.
The platform integrates with Azure Active Directory (Azure AD) for enterprise users and Auth0 for third-party vendors and partners. With MongoDB for secure storage and Golang powering high-performance REST APIs, the system ensures reliability and scalability—critical for utility providers managing large-scale infrastructure, distributed assets, and high-volume transactions.
Key Challenges Addressed
- Decentralized Identity Across Utility Systems: Utility organizations often operate with multiple microservices, IoT devices, and vendor applications without unified authentication.
- Compliance & Security: Ensuring strict adherence to data protection and industry regulations.
- Hybrid Identity Needs: Supporting enterprise staff (Azure AD) and external vendors (Auth0) in one secure system.
- Scalability: Managing high-frequency API requests from distributed systems and field applications.
- Reliability: Guaranteeing secure token issuance and validation without service downtime.
Technology Stack
- Backend: Golang
- Database: MongoDB
- Identity Providers: Azure AD, Auth0
- APIs: REST APIs for token management & authentication
- Tools: Git, Visual Studio Code, Postman (API testing)
Client Benefits
- Unified Security Layer: Provided a single authentication gateway for employees, partners, and vendors.
- Regulatory Compliance: Strengthened adherence to data security and industry compliance standards.
- Operational Continuity: High availability and secure token issuance ensured uninterrupted utility operations.
- Scalable Identity Management: Flexible enough to support both enterprise-scale users and IoT endpoints.
- Improved Vendor Collaboration: Enabled secure third-party system access without compromising core infrastructure.
Solutions Implemented
- Centralized Auth Service: Built MTNID to act as the single source of truth for authentication & authorization across all utility applications.
- Enterprise & Vendor Identity Integration: Connected with Azure AD for employees and Auth0 for external vendors/partners.
- Database Integration: Leveraged MongoDB to securely manage credentials, tokens, and audit logs.
- Secure Token Management: Implemented JWT-based token issuance and validation for distributed systems.
- Asynchronous Validation: Optimized performance by ensuring token validation and request handling scale with demand.
- Testing & Reliability: Developed robust test cases to validate integrations and ensure stable operations in mission-critical scenarios.
