Enterprise applications rarely have one type of user. Different employees need access to different information and actions based on their responsibilities.
While building Entouche IMS, role-based access control became an important part of the system architecture rather than simply a frontend feature.
The Four Core Roles
System Administrator
Warehouse Manager
Inventory Officer
Management Viewer
Roles and Permissions Are Different
A role describes a user’s responsibility within the system, while permissions determine the actions that role can perform. Keeping those concepts separate makes authorization easier to maintain as the application grows.
Authorization Must Be Enforced on the Backend
Hiding a button in the user interface is not sufficient security. Sensitive operations must also be authorized by the backend before they are executed.
This becomes particularly important for actions such as approvals, inventory adjustments, administrative configuration, and user management.
Designing for Future Roles
Permissions should be granular enough that new roles can be introduced without rewriting authorization logic throughout the application.
Key Lessons
Define responsibilities before defining permissions.
Enforce authorization on the server.
Avoid scattering role names throughout application logic.
Use permissions to keep the system extensible.
Record sensitive operations through audit logs.
