Reasoning-Based Authorization for Dynamic Least-Privilege Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Data Access Control (DAC) systems struggle with rigidity and inability to dynamically grant access to new or unpredictable requests, leading to security vulnerabilities, particularly in scenarios where support team members are granted broader access privileges than necessary.
Innovation Solution
A reasoning and intent-based authorization system that generates relational parameters and reasoning indicators from historical contextual information and intent indicators, evaluates these using response inputs on tasks, and grants access with the least required privileges based on successful validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional DAC systems grant broader access privileges to support team members to ensure they can resolve various issues, then the ease of operation is improved, but the security vulnerability increases due to excessive access rights
Solution Approach 1:
The patent implements dynamic access control where privileges are not static but adapt based on real-time contextual parameters. The system continuously evaluates relational parameters (user role, resource sensitivity, historical behavior, current task) to dynamically adjust access rights, granting only the minimum necessary privileges for each specific operation rather than broad static permissions
Solution Approach 2:
The system changes access control parameters based on multiple factors including user attributes, resource characteristics, historical access patterns, and current contextual information. By varying these parameters dynamically, the system optimizes the balance between operational ease and security, granting appropriate access levels for each specific scenario
2Device complexity
If conventional DAC systems require pre-configured access rules and entity attributes to be set up beforehand, then the device complexity is reduced, but the adaptability to new or unpredictable requests deteriorates
Solution Approach 1:
The system performs self-service by automatically generating access decisions without requiring pre-configured rules for every scenario. It autonomously evaluates contextual parameters, infers intent, and makes real-time access decisions for new entities or unpredictable requests, eliminating the need for manual pre-configuration while maintaining security
Solution Approach 2:
The patent introduces an intermediary reasoning layer that mediates between the access request and the decision-making process. This intermediary system analyzes contextual parameters, generates reasoning indicators, and determines appropriate access rights dynamically, bridging the gap between simple configuration and complex adaptability
3Reliability
If conventional DAC systems use static access rules to maintain security, then the reliability is improved, but the productivity deteriorates due to inability to make instantaneous access decisions for new requesters
Solution Approach 1:
The system performs preliminary actions by pre-establishing the framework for dynamic evaluation including relational parameters, contextual information collection mechanisms, and reasoning models. This preliminary setup enables instantaneous access decisions for new requesters without compromising security, as the decision-making infrastructure is already in place
Data Source
AI summary
An authorization system and related method is disclosed. The system receives an access request from a requester (human or machine). The system performs a series of steps in order to dynamically determine whether access has to be provided to the requester. The requester may be an unknown entity and access related policies may not be defined. The series of steps for dynamically granting access may include generating one or more relational parameters, generating one or more reasoning indicators, receiving, from the device associated with the requester, response inputs on a set of tasks associated with the requested resource, and validating the one or more reasoning indicators using the one or more relational parameters and the response inputs. Upon successful validation, access can be granted to the requester with least privileges required for the access.
