RBAC stands for Role-Based Access Control. It is a concept for managing and restricting access to resources within an IT system based on the roles of users within an organization. The main principles of RBAC include:
-
Roles: A role is a collection of permissions. Users are assigned one or more roles, and these roles determine which resources and functions users can access.
-
Permissions: These are specific access rights to resources or actions within the system. Permissions are assigned to roles, not directly to individual users.
-
Users: These are the individuals or system entities using the IT system. Users are assigned roles to determine the permissions granted to them.
-
Resources: These are the data, files, applications, or services that are accessed.
RBAC offers several advantages:
- Security: By assigning permissions based on roles, administrators can ensure that users only access the resources they need for their tasks.
- Manageability: Changes in the permission structure can be managed centrally through roles, rather than changing individual permissions for each user.
- Compliance: RBAC supports compliance with security policies and legal regulations by providing clear and auditable access control.
An example: In a company, there might be roles such as "Employee," "Manager," and "Administrator." Each role has different permissions assigned:
- Employee: Can access general company resources.
- Manager: In addition to the rights of an employee, has access to resources for team management.
- Administrator: Has comprehensive rights, including managing users and roles.
A user classified as a "Manager" automatically receives the corresponding permissions without the need to manually set individual access rights.
