Mechanical Air-Gap Switching for Secure Remote Site Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current approaches do not provide secure remote management of cloud systems across data boundaries, as air-gapping prevents management activities like software updates, while allowing direct communication poses security risks of data leakage.
Innovation Solution
An intermediary system with a switch component and mechanical control enables intermittent air-gapping between management and target sites, allowing secure data exchange through staged communication links, ensuring compliance with jurisdictional data retention requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct communication links are maintained between management site and target site, then remote management capabilities are enabled, but security risks and data leakage potential increase
Solution Approach 1:
The system performs preliminary actions by staging management code at the intermediary site before physically connecting to the target site. This allows validation and preparation of code in advance, reducing security risks while enabling subsequent remote management operations.
Solution Approach 2:
An intermediary site with air-gapped network switches is introduced between the management site and target site. This intermediary enables remote management capabilities while maintaining security boundaries, as it can receive code from the management site and deliver it to the target site without creating a direct communication path between them.
2Object-affected harmful factors
If air-gapped isolation is maintained between sites, then security and data protection are improved, but remote management activities are prevented
Solution Approach 1:
The network connection is segmented into distinct phases: a first connection for receiving management code at the intermediary site, and a second connection for delivering code to the target site. This segmentation allows air-gapped isolation to be maintained while still enabling remote management through sequential, controlled connections.
Solution Approach 2:
The system uses periodic, intermittent connections rather than continuous connectivity. The air-gapped network switches physically connect and disconnect at different times - first connecting the management site to the intermediary, then disconnecting and connecting the target site to the intermediary. This periodic action enables management activities while maintaining security isolation.
3Adaptability or versatility
If communication links are frequently connected and disconnected for management tasks, then management flexibility is improved, but system stability and security consistency deteriorate
Solution Approach 1:
The air-gapped network switches are configured with automated prerequisites that enforce security consistency. Before allowing a connection, the system automatically verifies that the target site is properly isolated from other networks. This self-service mechanism ensures security rules are consistently applied without manual intervention, maintaining stability while enabling flexible management operations.
Data Source
AI summary
Air-gapped security for a remote-managed site is provide through a system and related methods, the system including a switch component having at least one network switch, a staging component to stage data for communication between a first site, as a management site, and second site, as a target site to be managed by the management site, a mechanical component to selectively, physically connect and disconnect wired communication links to and from the switch component, and a control component to operate the mechanical component to physically disconnect a wired communication link to air-gap one site from the other site and the staging component as a prerequisite to physically connecting another wired communication link between the other site and the staging component via the switch component. Through selective connection and disconnection, secure provision of data between the first site and second site via the intermediate system is provided.
