Role-based access control (RBAC)

Role-based access control (RBAC) is a security model that grants permissions based on a user's role rather than to each individual, so people get exactly the access their job requires.

Definition

What is Role-based access control (RBAC)?

Role-based access control (RBAC) is a security model that grants permissions based on a user's role rather than to each individual, so people get exactly the access their job requires.

RBAC organizes permissions around roles. Instead of assigning access to each person one by one, you define roles - such as admin, manager, or member - each with a set of permissions, then assign people to roles.

This makes access easy to manage and audit. Changing what a role can do updates everyone in it, and reviewing who can do what becomes a question of roles rather than thousands of individual grants.

Atlas uses role-based access control so administrators can grant the right level of access across modules by role, keeping permissions consistent and reviewable.

FAQ

Questions, answered.

What is the benefit of role-based access control?
RBAC makes permissions consistent and easy to manage. You control access by role instead of per person, which simplifies onboarding, offboarding, and security audits.
What is the principle of least privilege?
Least privilege means giving each role only the access it needs to do its job and no more. RBAC is a common way to enforce it across an organization.
