Media Pool Security Attributes for Network Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network storage systems lack effective security measures that differentiate between storage devices and media, allowing unauthorized access to media contents, and require redundant permission settings for multiple storage media access.
Innovation Solution
A system and method for segregating storage media and device security attributes, allowing dynamic grouping of storage media and assigning security permissions based on user identities, enabling secure access to media pools across multiple client/server systems in a network environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If security permissions are assigned to each individual storage media, then access control precision is improved, but system complexity and redundancy increase
Solution Approach 1:
The patent merges multiple individual media security attributes into a pooled security attribute. Instead of managing security permissions for each storage media individually, the system creates a pooled security attribute that applies to the entire media pool, eliminating redundancy while maintaining granular access control through user identity-based permissions.
Solution Approach 2:
The pooled security attribute serves multiple functions simultaneously: it provides access control for all media in the pool, stores user identity permissions, and enables centralized security management. This universal attribute replaces multiple individual security configurations, reducing complexity while maintaining precision.
2Ease of operation
If security is associated with storage device rather than media, then device management is simplified, but media-level security control is lost
Solution Approach 1:
The patent segments security attributes into two distinct components: device security attributes and media security attributes. The pooled security attribute specifically addresses media-level security, while device security handles access to the storage device itself. This segmentation allows both simplified device management and robust media-level security control to coexist.
3Adaptability or versatility
If multiple users access the same storage device, then resource sharing is improved, but security control difficulty increases
Solution Approach 1:
The pooled security attribute acts as an intermediary between multiple users and the storage media pool. Instead of managing individual permissions between each user and each media, the system uses the pooled security attribute to mediate access control based on user identities, simplifying security control while enabling resource sharing.
