Auto-tuning Permissions via Learning Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual access control policy management in distributed systems is time-consuming, prone to errors, and becomes outdated as the needs of applications change, leading to security risks and delayed application development.
Innovation Solution
An auto-tuning permission system that monitors actual service and resource requests to generate and restrict access control policies dynamically, using a learning mode for applications in development and a continuous auto-tuning mode for those in production, eliminating the need for manual policy writing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual access control policies are used, then security can be maintained, but the system becomes time-consuming and error-prone to manage
Solution Approach 1:
The system automatically generates and updates access control policies by monitoring actual service requests and analyzing usage patterns. The policy management system performs self-service by continuously tuning policies without manual intervention, thereby maintaining security while eliminating time-consuming manual management tasks.
Solution Approach 2:
The system implements continuous monitoring of service requests and usage patterns, feeding this information back to the policy generation engine. This feedback loop enables automatic policy updates that adapt to changing system conditions, maintaining security while reducing manual management overhead through automated decision-making based on observed behavior.
2Reliability
If manual access control policies are used, then initial security can be established, but policies become outdated as application needs change
Solution Approach 1:
The system transitions from static manual policies to dynamic automated policies that continuously adapt to changing application needs. By monitoring service requests in real-time and analyzing usage patterns, the system automatically updates policies to reflect current application requirements, ensuring both security and adaptability simultaneously.
Solution Approach 2:
The policy management system operates continuously, constantly monitoring service requests and updating policies without interruption. This continuous operation ensures policies remain current with application needs, preventing outdatedness while maintaining security through uninterrupted adaptive management.
3Productivity
If broad access permissions are granted during development, then application development is accelerated, but security risks increase
Solution Approach 1:
The system performs preliminary monitoring of service requests during the development phase, collecting data on actual usage patterns before finalizing policies. This preliminary action allows the system to understand necessary access requirements early, enabling rapid development with appropriately scoped permissions from the start rather than granting overly broad access.
Solution Approach 2:
The system initially permits broader access during development to accelerate productivity, then systematically refines permissions by analyzing actual usage patterns and removing unnecessary access. This partial action approach allows temporary excessive permissions during development while planning for subsequent refinement to eliminate security risks.
4Measurement precision
If comprehensive access monitoring is implemented, then policy accuracy is improved, but system complexity increases
Solution Approach 1:
The monitoring system serves multiple functions simultaneously: it collects service request data, analyzes usage patterns, generates policy recommendations, and validates policy effectiveness. By consolidating these functions into a single multi-functional system rather than separate components, the system achieves comprehensive monitoring for accurate policies without proportionally increasing overall system complexity.
Data Source
AI summary
Methods, systems, and computer-readable media for auto-tuning permissions using a learning mode are disclosed. A plurality of access requests to a plurality of services and resources by an application are determined during execution of the application in a learning mode in a pre-production environment. The plurality of services and resources are hosted in a multi-tenant provider network. A subset of the services and resources that were used by the application during the learning mode are determined. An access control policy is generated that permits access to the subset of the services and resources used by the application during the learning mode. The access control policy is attached to a role associated with the application to permit access to the subset of the services and resources in a production environment.
