Centralized Role-Based Access Control (RBAC) and Identity Management Server

This project proposes the design and prototype of a centralized Role-Based Access Control (RBAC) and Identity Management server that helps system administrators, developers, and internal services securely manage user authorization and resource access without requiring repetitive perimeter security logic at every application layer. The solution will explore how modern backend architectures, including Token-Based Authentication (JWT), secure cryptographic hashing algorithms, optional middleware interceptors, and relational data modeling can simplify user lifecycle management, session tracking, and API-layer security enforcement. The project emphasizes core system architecture principles such as the Principle of Least Privilege (PoLP), strict segregation of duties, data isolation, inspectable audit logging, and reduced dependency on complex third-party identity providers. Expected outcomes include a functional demo, technical architecture documentation, a comprehensive permission matrix/schema analysis, a security and privilege-escalation threat model analysis, and an open-source repository that demonstrates how centralized authorization can secure microservice environments while preserving application performance, data integrity, and operational transparency.
