RBACABACfor

RBACABACfor is a proposed authorization model that combines Role-Based Access Control (RBAC) with Attribute-Based Access Control (ABAC). The goal is to leverage the strengths of both approaches to create a more flexible and granular system for managing access to resources. In a pure RBAC system, permissions are assigned to roles, and users are assigned roles. This can become cumbersome in large or dynamic environments where roles might not perfectly align with user responsibilities or where fine-grained control is needed. ABAC, on the other hand, uses attributes associated with users, resources, and the environment to make access decisions. While powerful, ABAC can sometimes be complex to manage due to the multitude of attributes and policies. RBACABACfor seeks to bridge this gap by using roles as a primary grouping mechanism, but then allowing attributes to further refine the permissions associated with those roles. For instance, a role like "Manager" might grant access to employee records, but an ABAC component could specify that this access is only permitted during business hours or for employees within the manager's direct reporting line. This hybrid approach aims to simplify role management while retaining the precision of attribute-based policies. The "for" in RBACABACfor suggests a potential emphasis on its application or suitability for specific contexts, though the exact scope of this emphasis would depend on the full specification of the model. Development and adoption of such hybrid models are ongoing in the field of information security and access management.
