What is Role-Based Access Control (RBAC)? - Definition & Meaning
RBAC is a security model where access rights are assigned based on roles within an organization. Learn how RBAC works.
Definition
Role-Based Access Control (RBAC) is a security model where users receive access rights based on their role within the organization, rather than individual permissions. Roles such as "admin," "project manager," and "developer" define which actions a user can perform and which data they can view.
Technical Explanation
RBAC implements the principle of least privilege: users receive only the minimum rights needed for their function. The model consists of users, roles, and permissions. Users are assigned to roles, and roles contain sets of permissions. Hierarchical RBAC supports role inheritance where higher roles inherit the permissions of lower roles. Constraints like separation of duties prevent a single user from combining conflicting roles. In software, RBAC is implemented via middleware that checks the role and permissions on every request. ABAC (Attribute-Based Access Control) is a more advanced alternative that also considers context (time, location, device).
How Refront Uses This
Refront implements RBAC to ensure team members only have access to information and features relevant to their role. Administrators configure roles with specific permissions for ticket management, invoicing, reporting, and client data. The client portal has a separate role structure that gives clients access to their own project data without seeing internal information.
Examples
- •A developer can view and edit tickets but has no access to financial reports or invoicing.
- •The client sees only their own projects and tickets through the portal, not those of other clients.
- •An administrator can invite new team members and assign roles, while a project manager can only manage team composition per project.

Frequently Asked Questions
What is the difference between RBAC and ABAC?
RBAC assigns rights based on roles. ABAC (Attribute-Based Access Control) is more flexible and also considers attributes like time, location, device type, and other contextual information when determining access rights.
How many roles should an organization define?
Keep it as simple as possible. Start with 3-5 basic roles (admin, manager, member, client) and only add extra roles when there is a genuine need for more granular access control.
How does RBAC help with GDPR compliance?
RBAC ensures only authorized employees have access to personal data, which is a core GDPR requirement. Combined with an audit trail, it can be demonstrated who has had access to which data.
