Bridge Application Relay for Traceless Remote Device Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote access methods for computing devices in undisclosed locations expose devices to attack surfaces, reveal sensitive deployment information, and create forensic records that can be exploited by malicious entities.
Innovation Solution
A bridge application establishes secure connections between a remote device and a support server, allowing only authenticated inbound connections, and uses cryptographic URLs to ensure traceless access, ensuring no forensic records are left on the device or server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct network access is provided to remote devices, then technicians can troubleshoot and maintain devices, but attack surfaces are created for malicious hackers
Solution Approach 1:
A bridge application is introduced as an intermediary component deployed on the remote device. This bridge acts as a mediator that receives authenticated requests from support servers and establishes secure relay connections, preventing direct network access while enabling authorized remote maintenance. The bridge application validates incoming requests and manages connection relay, thereby eliminating the attack surface of direct access while preserving legitimate maintenance capabilities.
2Ease of operation
If network addresses are provided to technicians, then remote access is enabled, but sensitive deployment location information is revealed
Solution Approach 1:
The bridge application serves as a network intermediary that decouples the support server from the remote device's actual network address. The support server communicates with the bridge through a relay connection rather than directly accessing the remote device's network address. This intermediary mechanism enables remote access functionality while preventing the exposure of sensitive deployment location information that would otherwise be revealed through direct address provision.
3Productivity
If direct communication channels are established, then troubleshooting efficiency is improved, but forensic records are created that can be exploited by malicious entities
Solution Approach 1:
The bridge application functions as a communication intermediary that relays data packets between the support server and remote device without creating traditional forensic records. All communication flows through the bridge, which manages connection state and data relay while preventing direct communication channels that would generate exploitable forensic records. The bridge's authenticated request-handling mechanism enables efficient troubleshooting through structured interaction while eliminating the creation of direct communication forensic traces.
4Ease of operation
If network connections are allowed between technician and device, then maintenance operations can be performed, but man-in-the-middle attacks become possible
Solution Approach 1:
The bridge application serves as a trusted intermediary that establishes secure relay connections between the support server and remote device. Rather than allowing direct peer-to-peer connections that are vulnerable to man-in-the-middle attacks, the bridge manages authenticated connection relay with cryptographic verification. The bridge validates the support server's authenticated request and establishes encrypted communication channels, enabling remote maintenance operations while preventing man-in-the-middle attacks through the intermediary's control over connection establishment and data relay.
Data Source
AI summary
A bridge application receives a request from a remote device to access a support server. Subsequently, the bridge application established a secure connection between the bridge application and the support server and establishes a secure connection between the bridge application and the remote device. Once these secure connections are both established, communications are relayed between the remote device and the support server to effect a software change to network device. The secure connections are later terminated upon completion of the software change to the remote device. Related apparatus, systems, techniques and articles are also described.
