The RBAC model is a role-based approach to access control that facilitates authorization management by assigning roles to users, rather than defining "roles". permissions for each individual user. This improves safety and simplifies IT system administration

RBAC stands for "Role-Based Access Control". It's an access control model used to manage permissions and authorizations in IT systems.

In the RBAC model, users are assigned roles, and permissions are granted to roles rather than individual users. This enables more efficient authorization management, by grouping users according to their responsibilities and privileges.

The RBAC model is based on three main concepts: roles, permissions and entities.

Roles represent the different categories of users or the functions they perform within a system. For example, a system may have roles such as "administrator", "normal user" or "moderator".

Permissions are the access rights granted to roles. They define the specific actions a role can perform. For example, a permission might be "create new user" or "read customer data".

Entities, on the other hand, refer to individual users, user groups or other objects to which permissions can be assigned.

With RBAC, administrators can assign specific roles to users according to their needs and responsibilities. For example, an administrator can assign the administrator role to a member of the IT team, while a normal user can have the limited access role. This simplifies authorization management and reduces the risk of unauthorized access to resources.
