Remote Agent Security for Storage Namespace Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage system environments face security vulnerabilities due to centralized administration of privileges by namespace servers, which can lead to potential security failures if compromised, and are limited by incompatibility and non-interoperability across heterogeneous platforms.
Innovation Solution
A remote agent is installed on a host machine with assigned privileges, allowing a namespace and storage management server to dynamically establish trust relationships across domains, offloading privilege administration and enabling remote agent-based management, along with defining user rights and implementing a multi-stage authentication procedure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a namespace server centrally administers privileges for host machines, then management control is centralized and simplified, but security risk increases because compromise of the namespace server leads to potential security failures across all domains
Solution Approach 1:
The patent extracts the privilege administration function from the namespace server and relocates it to remote agents installed on individual host machines. This extraction eliminates the security vulnerability of centralized privilege management while preserving the ability to manage privileges across multiple domains through the distributed agent architecture.
Solution Approach 2:
The patent segments the centralized privilege administration into distributed components by installing separate remote agents on each host machine. Each agent independently manages privileges for its local machine, creating a segmented security architecture where compromise of one agent does not affect others, thus reducing overall security risk while maintaining management capability.
2Ease of operation
If a namespace server is used to manage storage resources across heterogeneous platforms, then centralized management is achieved, but interoperability is limited due to platform incompatibility
Solution Approach 1:
The patent implements universality by designing remote agents that can operate on multiple different operating system platforms (Windows, Unix, Linux, etc.). Each agent adapts to its local platform's conventions and APIs, enabling the namespace management system to work across heterogeneous environments without requiring a single proprietary platform.
Solution Approach 2:
The remote agents serve as intermediaries between the namespace server and the local host machines. They translate between the platform-independent namespace management protocols and platform-specific operating system calls, enabling interoperability across heterogeneous platforms while maintaining centralized namespace management capability.
3Ease of operation
If pre-configured trust relationships are established between namespace server and host machines, then security is simplified, but flexibility is reduced and security vulnerabilities increase
Solution Approach 1:
The patent implements self-service by enabling remote agents to dynamically establish their own trust relationships with the namespace server without requiring pre-configuration. Each agent independently negotiates and establishes secure communication channels, eliminating the need for manual trust relationship setup while maintaining security and increasing flexibility.
Solution Approach 2:
The patent replaces static pre-configured trust relationships with dynamic trust establishment. Trust relationships are created on-demand when agents first connect to the namespace server, allowing the system to adapt to changing security requirements and platform configurations without requiring reconfiguration of trust relationships.

AI summary
A system and method administers security in a logical namespace of a storage system environment. A remote agent performs an integral security-related role within a management framework that is directed to off-loading administration of privileges from a namespace and storage management (NSM) server for namespace and storage management. NSM server rights are defined and assigned to a user of the NSM server in accordance with a security administration feature of the management framework. In addition, a multi-stage authentication procedure is provided to ensure that a user has the appropriate rights to perform operations on the NSM server.
