Role-Based Access Control
Also known as: RBAC
Governance
RBAC assigns permissions to roles, and roles to people. Designed well, roles map to durable job functions so access follows what someone does, granting birthright access, functional roles, and requestable add-ons.
Why it matters
RBAC makes access consistent, auditable, and easy to grant or revoke as people join, move, and leave — provided roles are modeled around job functions rather than the org chart.
