RBAC

Role-Based Access Control

RBAC stands for Role-Based Access Control. It is a method of restricting access based on users’ roles within an organization. In RBAC, authorizations are associated with roles, and users are assigned to specific roles based on their job responsibilities or functions within the organization.

Key components of RBAC include:

1. Roles: Roles represent a collection of authorizations that are typically associated with a specific job function or responsibility. For example, an organization might have roles such as “Administrator,” “Manager,” or “User.”

2. Authorizations: Authorizations define the actions that users within a particular role are allowed to perform. These can include read, write, execute, or other specific actions depending on the context.

3. Users: Users are individuals or entities within the system who are assigned to specific roles. By being part of a role, users inherit the authorizations associated with that role.

4. Access Control: RBAC enforces access controls based on roles and their associated authorizations. This ensures that users only have the necessary access rights to perform their job functions and nothing more.

Benefits of RBAC include simplified administration, and better adherence to the principle of least privilege, where users are granted the minimum level of access required to perform their tasks.
