Exclusive Scope Model for Role-Based Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Role-based access control (RBAC) systems face challenges in permission auditing and managing exclusive access for specific users or objects, leading to inconsistencies and potential unintended access, especially in complex enterprise environments.
Innovation Solution
The introduction of 'exclusive' role-based scopes that automatically restrict access to resources unless explicitly granted, ensuring that users can only access specified scopes and immediately write-protecting them upon creation, thereby preventing accidental exposure of sensitive resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional RBAC scopes are used to manage access control, then flexibility in assigning permissions is improved, but permission auditing becomes difficult and permission consistency deteriorates
Solution Approach 1:
The patent segments the scope definition into two distinct parts: the scope itself (defining what resources are accessed) and the scope type (defining the access control behavior). This segmentation allows the system to maintain flexible scope assignments while applying consistent access control rules through scope types, thereby improving both flexibility and auditing capability simultaneously.
2Productivity
If traditional RBAC model is used for general administration, then broad access control is achieved, but focused role management for specific individuals becomes difficult
Solution Approach 1:
The patent applies local quality by allowing different scope types (such as exclusive scopes) to be applied to specific resources or resource sets while maintaining general RBAC for other resources. This enables focused role management for specific individuals or resources without disrupting the overall general administration efficiency, as administrators can selectively apply specialized scope types where needed.
3Ease of operation
If filters are added to exclude specific objects in RBAC, then focused administration is attempted, but system complexity and error probability increase
Solution Approach 1:
The patent creates a universal scope type mechanism that can serve multiple functions: exclusive scopes can exclude specific objects, be immediately write-protected, and still integrate with the general RBAC framework. This multi-functionality allows focused administration without requiring separate filter mechanisms, thereby reducing system complexity while maintaining the capability for focused role management.
4Measurement precision
If new scopes are created to define exclusives, then access control precision is improved, but administrative burden and error risk increase
Solution Approach 1:
The patent applies preliminary action by enabling exclusive scopes to be immediately write-protected upon creation. This automatic write-protection is performed in advance before any potential errors can occur, reducing the administrative burden of manually managing permissions while maintaining high access control precision. The system proactively prevents unintended access rather than requiring continuous manual oversight.
Data Source
AI summary
Architecture that creates a class of role-based scopes that can be declared “exclusive”, which automatically means that no user can access the scope unless the user is granted that exact scope. The exclusive scope excludes an object from the new scopes and existing scopes. In other words, the exclusive scope is a write restriction from a domain scope. The exclusive scope denies user access unless the user is granted the exclusive scope. The exclusive scope can be applied to a group of user objects. The exclusive scope is explicitly assigned to the object to grant access to an exclusive group. Moreover, the exclusive scope is immediately write-protected upon creation.
