Dynamic Role-Based Access Control via Client Reputation Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing role-based access control systems in enterprise organizations do not dynamically adjust access privileges based on client device behavior, leading to potential misbehavior and reduced productivity.
Innovation Solution
Implementing a system that monitors client device activity, assigns a reputation score, and dynamically modifies access privileges by downgrading or upgrading roles based on this score, with thresholds for restricting access or blacklisting devices that misbehave.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If role-based access control is assigned statically to client devices, then ease of operation is improved, but adaptability deteriorates
Solution Approach 1:
The patent implements dynamic role assignment where client devices automatically transition between roles (e.g., from 'full-access' to 'restricted-access') based on real-time reputation scores. This dynamic mechanism resolves the contradiction by making access control adaptable to changing device behavior while maintaining operational simplicity through automated transitions without manual intervention.
Solution Approach 2:
The system continuously monitors client device activity, calculates reputation scores, and uses this feedback to automatically adjust access privileges. This closed-loop feedback mechanism enables the system to adapt to device behavior changes in real-time, resolving the adaptability issue while maintaining ease of operation through automated decision-making based on predefined policies.
2Ease of operation
If access privileges are not dynamically restricted, then ease of operation is improved, but productivity deteriorates
Solution Approach 1:
The system enables self-service access control where client devices automatically receive appropriate access levels based on their own behavior and reputation scores. Misbehaving devices are automatically downgraded to restricted roles without manual intervention, preventing productivity loss from misbehavior while maintaining ease of operation through automated enforcement of access policies.
Solution Approach 2:
By implementing dynamic role transitions based on real-time monitoring and reputation scoring, the system automatically adjusts access privileges to match current device behavior. This ensures that misbehaving devices are promptly restricted to prevent productivity degradation, while compliant devices maintain full access, all without requiring manual operational intervention.
3Adaptability or versatility
If dynamic reputation-based access control is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a centralized access control server that acts as an intermediary, handling all reputation score calculations and role assignment decisions. This centralizes the complexity of the dynamic access control system, allowing client devices to remain relatively simple while still achieving high adaptability through the intermediary's automated decision-making based on monitored device behavior.
4Reliability
If continuous monitoring of client activity is performed, then reliability is improved, but use of energy increases
Solution Approach 1:
The system implements periodic monitoring and reputation score updates rather than continuous monitoring. Access control decisions are refreshed at intervals based on significant events or time-based triggers, maintaining system reliability by detecting misbehavior while reducing energy consumption by avoiding constant monitoring and processing of all device activities.
Data Source
AI summary
The present disclosure discloses a system and method for dynamically modifying role based access control for a client based on the activity. Generally, a client device is granted access to a network resource based on a first reputation score assigned to the client device. The activity of the client device is monitored. Responsive to monitoring the activity of the client device, a second reputation score is determined for the client device based on the activity. The access by the client device to the network resource is then modified to be granted based on the second reputation score.
