SECURITY RE-DESIGN FOR LOGISTICS ENTERPRISE
A logistics industry client encountered considerable security and integration issues stemming from their disjointed legacy software systems. The software comprised various sub-systems, each created independently by different teams, resulting in inconsistent security measures. Protagonist carried out a comprehensive evaluation and devised a strong security strategy. Through this assessment, we discovered 50 opportunities for security and architectural enhancements, which were organized into 11 primary security categories for a more systematic implementation. A major emphasis was placed on authentication and authorization, which led to the architectural vision of an Identity Broker. We recommended adopting Auth0 to manage identity federation and simplify authentication processes across various sub-systems. For authentication, Auth0 was implemented for customer logins, while Microsoft Entra ID was used for employee authentication, establishing a secure, role-based access system. Authorization protocols were designed so that target systems granted access based on factors like roles, session duration, and access levels, all managed by the identity provider (Auth0). To ensure compatibility and secure integration across all platforms, we standardized authentication and authorization using OpenID Connect, OAuth, SAML, and JWT. The client was provided with a comprehensive security roadmap structured around Architecture Building Blocks (ABB), offering a clear plan for implementation that included step-by-step decomposition, prioritization by security risks, and strategies for resource allocation. This approach guaranteed a structured and precise security transformation, achieving key objectives while enhancing user experience, operational efficiency, and risk management.
