RBAC and ABAC: The access control models you should know

Role-based access control (RBAC) and attribute-based access control (ABAC) are two popular models for managing user access to resources. RBAC assigns permissions based on user roles, simplifying permission management but lacking flexibility for complex policies. ABAC, on the other hand, uses attributes to define policies, allowing for more dynamic and fine-grained access control but at the cost of increased complexity and potential performance impact. The choice between the models depends on the system's requirements, with practitioners often combining both to balance simplicity and flexibility.
