What is Role-Based Access Control?
Role-based access control, often shortened to RBAC, is a model where permissions are assigned to roles instead of being assigned one-by-one directly to every person.
What it is
RBAC is an access control model built around roles such as administrator, analyst, editor, or support agent.
Instead of giving each user individual permissions manually, organizations assign permissions to roles and then assign users to those roles.
How it works
A role represents a function or job need. The permissions associated with that function are attached to the role.
Users then inherit the correct access when they are assigned the role.
Why it matters in real life
RBAC matters because it makes access management more organized, scalable, and easier to review.
It also supports least privilege by helping organizations define access around actual functions rather than broad default access.
Common misconceptions
A common misconception is that RBAC is the same as any access control system. In reality, RBAC is one specific model built around roles.
Another misconception is that RBAC eliminates the need for access reviews. It still requires governance and thoughtful role design.
Related questions
What is RBAC in simple terms?
