About This Architecture

Role-based access control (RBAC) multi-role system with four distinct user tiers—Admin, Executive, Coordinator, and Technician—each accessing role-specific modules through a centralized IAM and RBAC engine. Client devices connect via ISP and Internet through a hardened perimeter including external firewall, WAF, and load balancer, then authenticate at the Auth Server before reaching the VPN Gateway and internal firewall. The RBAC Engine enforces least-privilege access, routing authenticated users to their designated modules (Admin, Executive, Coordinator, Technician) with granular permissions to application servers, cache, object storage, and databases. This architecture demonstrates defense-in-depth with network segmentation, centralized identity management, and audit logging for compliance.

How do I design a role-based access control system that enforces least-privilege access for multiple user roles?

This RBAC multi-role architecture uses a centralized IAM Auth Server and RBAC Engine to authenticate users and route them to role-specific modules (Admin, Executive, Coordinator, Technician), each with granular permissions to application servers, databases, and storage. Defense-in-depth perimeter security (external firewall, WAF, load balancer) protects the authentication layer, while audit loggin
