In Rule-Based Access Control (RB-RBAC), access permissions are based on what?

In Rule-Based Access Control (RB-RBAC), access permissions are determined by predefined access policies established by the system. This means that administrators define specific rules that dictate what resources users can access under certain conditions. These policies often take into account various factors, such as the roles of users, their attributes, or environmental conditions, to grant or deny access.

This method provides a high level of security and flexibility, as it allows for automated access management based on the established rules, rather than relying on individual user characteristics or feedback. The focus on systematic policies ensures consistency and efficiency in access control, which is critical in environments where data security and compliance with regulatory standards are vital.
