How is RBAC different from ABAC and ACL?
RBAC differs from attribute-based access control (ABAC) because it’s based on employee roles rather than user characteristics, such as environment, action types, and more. ABAC attributes tend to fall into four categories: subject, action, object, and contextual. These attributes cover things like age, clearance, and department as well as the action being taken, the object being accessed, and other relevant environmental attributes.
ACL, or access-control list, technology is a user-specific list of permissions that determines which users have access to specific files, systems, processes, and resources. An ACL also determines which actions that user can take. Unlike RBAC, which clusters users together and determines access privilege based on their role, ACL is done at the user and resource level. Typically, ACL works better for individual users while RBAC works better on a company level.
