What does RBAC stand for in access control systems?

Role-Based Access Control (RBAC) is a key concept in access control systems that restricts system access to authorized users based on their roles within an organization. In this model, permissions are assigned to specific roles rather than to individual users. Users are then assigned roles based on their job functions or responsibilities, which facilitates a more organized and efficient access control management process.

Using RBAC enhances security by ensuring that individuals only have the permissions necessary to perform their job functions, thereby minimizing the risk of unauthorized access to sensitive information and systems. This framework aligns with the principle of least privilege, which is a fundamental aspect of information security.

The other options do not accurately represent established concepts in access control systems. Resource-Based Access Control is not a recognized method; the focus is more on roles than resources. Regulatory-Based Access Control implies compliance with regulations but doesn't define how access is managed. Random-Based Access Control suggests an arbitrary method that would conflict with the structured nature of access control. Thus, Role-Based Access Control is the most relevant and widely implemented model in various organizations.
