Multi-Region Login Authentication Replication for Regional Failover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud service providers face challenges in managing multi-region login attempts with existing security measures, particularly when regions become unavailable, leading to potential security vulnerabilities and user access disruptions.
Innovation Solution
Implementing a framework that replicates authentication information across multiple regions of a cloud service provider, allowing login credentials to be validated across these regions using synchronized back channels, ensuring secure and reliable access management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information is stored in a single entity and all login attempts are directed to that entity, then security protection is achieved through centralized tracking of single-use passwords and failed login attempts, but the system becomes vulnerable when that single entity is unavailable and does not support multi-region access
Solution Approach 1:
The patent divides the centralized authentication entity into multiple distributed authentication entities across different regions. Each region maintains its own authentication information including single-use passwords and failed login attempt tracking, allowing login operations to continue in available regions even when others are unavailable.
Solution Approach 2:
The patent creates copies of authentication information across multiple regional entities. When a login request is made, the system queries multiple regions for authentication information, and upon successful authentication in one region, the authentication state is replicated to other regions to maintain consistency and security across the distributed system.
2Ease of operation
If the system directs all login attempts to a single entity for security tracking, then security monitoring is effective, but user access is disrupted when that entity becomes unavailable
Solution Approach 1:
The patent segments the authentication functionality across multiple independent regional entities, each capable of handling login requests and maintaining security tracking locally. This allows users to access services through any available region while security monitoring continues through distributed tracking of authentication credentials.
Solution Approach 2:
The patent implements a feedback mechanism where authentication results from one region are communicated to other regions through replication. When a login is successfully authenticated in one region, this authentication state is fed back to other regions, ensuring consistent security monitoring across the distributed system without requiring all regions to be simultaneously available.
3Adaptability or versatility
If the system uses single-use passwords with centralized tracking, then security against unauthorized access is maintained, but the system cannot support login from multiple regions simultaneously
Solution Approach 1:
The patent segments authentication information storage and processing across multiple regional entities, each maintaining local records of single-use passwords and failed login attempts. This enables users to authenticate from any region while preserving security through distributed tracking of credential usage.
Solution Approach 2:
The patent creates and maintains copies of authentication information across multiple regions. When authentication credentials are used or invalidated in one region, this state is replicated to other regions, ensuring that security protections against unauthorized access are maintained consistently across all regions supporting multi-region login capability.
