Definition
Role-Based Access Control structures permissions around defined roles rather than managing every permission independently for each user. This can make access governance more consistent, scalable and auditable, especially in larger organizations.
Why it matters
Role-Based Access Control matters because it helps organizations give users access according to their responsibilities instead of managing every permission individually. This supports clearer separation of duties, more consistent access governance and easier review of who can do what.
Create roles that map to meaningful job or process responsibilities rather than individual users.
Define roles around responsibilities
•
Grant each role the data and functions required for its work while limiting unnecessary access.
Assign permissions to roles
•
Use approved role assignment based on current responsibilities and organizational placement.
Assign users through governed membership
•
Avoid role combinations that allow one person to create, approve and conceal sensitive transactions where separation is needed.
Consider segregation of duties
•
Periodically check role definitions and user assignments for changes in organization, process or risk.
Review roles and membership
•
Maintain enough Audit Trail information to understand material role changes, administrative actions and access decisions.
Retain access history

How Role-Based Access Control governs permissions
RBAC assigns permissions to defined roles and then assigns users to those roles, reducing the need to manage every permission individually. Good RBAC design reflects real responsibilities, Least Privilege and controlled review rather than creating broad roles for convenience.
