File System Mounting Authorization via Network Attribute Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling the mounting of file systems in distributed systems lack efficient permission management, leading to potential unauthorized access and lack of secure authentication mechanisms.
Innovation Solution
A method and system that receive network attribute information from a target client, determine permission based on verification information sets, and send an identification of the file system to the target server, utilizing encryption and decryption algorithms for secure authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional configuration file methods are used for file system mounting, then ease of operation is improved, but security and reliability deteriorate due to lack of authentication mechanisms
Solution Approach 1:
The patent introduces an authorization server as an intermediary component between clients and file systems. This server receives mounting requests, verifies client credentials against stored verification information, and grants or denies access accordingly. This mediator resolves the contradiction by adding security functionality without requiring changes to the file system itself, maintaining ease of operation while significantly improving reliability through authenticated access control
2Reliability
If verification mechanisms are added to control file system mounting, then security is improved, but device complexity worsens due to additional authentication components
Solution Approach 1:
The authorization server is designed as a multi-functional component that handles credential verification, client authentication, and mounting permission management. By consolidating these security-related functions into a single universal server, the system improves security without proportionally increasing overall complexity. The server can serve multiple file systems and clients simultaneously, amortizing the complexity across multiple operations
Solution Approach 2:
The system implements self-service authentication where clients present their own credentials (such as certificates or tokens) for verification. The authorization server automatically compares these credentials against stored verification information without requiring manual intervention. This automated self-service approach improves security while minimizing the operational complexity that would otherwise be required to manage authentication manually
3Reliability
If network attribute information is collected and verified, then reliability is improved through better authentication, but loss of information increases due to handling and processing overhead
Solution Approach 1:
The patent extracts only the essential authentication-related network attributes (such as client identifiers, credentials, or security tokens) from the complete network attribute information set. By taking out only the necessary verification data and leaving out unnecessary details, the system achieves reliable authentication while minimizing information processing overhead. This selective extraction reduces the amount of data that needs to be transmitted, stored, and processed during authentication operations

AI summary
Embodiments of the present disclosure disclose a method, apparatus and system for controlling mounting of a file system. A specific embodiment of the method includes: receiving network attribute information of a target client sent by a target server as first network attribute information; determining, based on the first network attribute information, whether the target client has permission to mount to a target file system; and sending, in response to determining that the target client has permission to mount to the target file system, an identification of the target file system to the target server.
