RBAC Policy Management Service Dynamic Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Role-Based Access Control (RBAC) systems face inefficiencies due to bloated rule-bases and convoluted code paths resulting from dynamic permission changes, leading to unnecessary resource utilization and potential vulnerabilities from inactive access permissions.
Innovation Solution
An access policy management service dynamically updates policy sets and decision logic by identifying and removing access policies associated with revoked services, using feature flags to prevent execution of obsolete decision paths, and executing scripts within virtual environments to validate and deploy updated policy decision points without downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic permission changes are implemented in RBAC systems, then adaptability is improved, but device complexity increases due to bloated rule-bases and convoluted code paths
Solution Approach 1:
The patent extracts and removes obsolete access policies and decision execution paths from the RBAC system when services are revoked. The access policy management service identifies and removes policies associated with revoked services from policy sets, and removes corresponding decision execution paths from the policy decision point, thereby preventing rule-base bloat while maintaining adaptability
Solution Approach 2:
The patent implements dynamic management of the policy decision point by allowing it to be updated without system downtime. The system can add, modify, or remove policies and decision execution paths dynamically based on service lifecycle events, making the RBAC system adaptable while maintaining operational continuity
2Ease of operation
If obsolete access policies are retained in the system, then ease of operation is improved, but reliability deteriorates due to potential vulnerabilities
Solution Approach 1:
The patent implements a feedback mechanism where the access policy management service monitors service lifecycle events (creation, revocation) and automatically responds by updating the policy decision point. When a service is revoked, the system detects this event and triggers removal of associated policies and decision execution paths, ensuring the system state remains consistent and secure without manual intervention
3Loss of substance
If the policy decision point is updated with removed services, then loss of substance is improved, but productivity decreases due to system downtime
Solution Approach 1:
The patent performs preliminary validation of the updated policy decision point in a virtual environment before deploying it to production. The system validates the updated PDP code, checks for syntax errors and logical consistency, and only deploys after successful validation, preventing deployment failures that would cause downtime and ensuring smooth updates without productivity loss
Data Source
AI summary
A method includes determining that access permissions associated with a service of a computing system have been revoked, identifying one or more access policy sets including access policy rules associated with the service, removing the access policy rules associated with the service from the one or more access policy sets, and marking one or more decision execution paths of a policy decision point associated with the service with a feature flag.
