Rugged Firewall Self-Reset for OT Physical Intrusion Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network security systems are inadequate in protecting network data from physical intrusions of operational technology (OT) devices, which are susceptible to physical breaches alongside remote hacking, lacking robust security measures.
Innovation Solution
Implementing a rugged firewall with a GPS sensor to monitor the current position of OT devices, detect deviations from a tolerable threshold, and initiate a self-reset to destroy sensitive network data upon intrusion detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional alarm systems are used to protect OT devices, then physical break-in prevention is improved, but network data protection capability deteriorates
Solution Approach 1:
The patent combines traditional physical alarm systems with network security capabilities into a unified rugged firewall device. The firewall integrates GPS location tracking, physical intrusion detection sensors, and network data protection functions, allowing simultaneous protection against both physical break-ins and network cyber-attacks. This merging resolves the contradiction by making a single device capable of addressing both security domains.
Solution Approach 2:
The rugged firewall is designed as a multi-functional device that performs traditional firewall operations plus physical intrusion detection, GPS location monitoring, and data destruction capabilities. By making the security system universal, it can respond to both physical and digital threats, eliminating the need for separate specialized systems and resolving the limitation of traditional alarm systems.
2Loss of information
If traditional firewall systems are used to protect network data, then remote hacking prevention is improved, but physical intrusion detection capability deteriorates
Solution Approach 1:
The patent merges network security functions with physical security capabilities in a single rugged firewall platform. The system combines software-based firewall operations with hardware-based physical intrusion sensors, GPS location tracking, and data destruction mechanisms, enabling simultaneous protection against remote hacking and physical tampering.
Solution Approach 2:
The rugged firewall acts as an intermediary system that bridges physical security monitoring and network security functions. It serves as a mediator between physical intrusion detection and data protection operations, coordinating responses to both physical and digital threats through a unified security architecture.
3Object-affected harmful factors
If GPS monitoring and self-reset are implemented, then physical intrusion detection is improved, but device complexity increases
Solution Approach 1:
The rugged firewall implements self-service security measures including automatic GPS location tracking, autonomous intrusion detection, and self-executing data destruction upon intrusion detection. The system monitors itself and takes corrective action without requiring external intervention, reducing the need for complex external monitoring and control systems.
Solution Approach 2:
The system performs preliminary actions by continuously monitoring GPS location and detecting physical intrusions before they can lead to data breaches. The self-reset mechanism is pre-configured to automatically execute data destruction upon intrusion detection, eliminating the need for complex real-time response systems and reducing overall system complexity.

AI summary
A rugged firewall of an OT device includes sensitive network data stored on a memory device. A current GPS position of an OT device is determined, and a tolerable deviation in GPS position is received for the OT device from the current GPS position as defined by a network security policy. A violation of the tolerable deviation is detected in the OT device from the current GPS position. In response to the detected violation, a security action involving a self-reset is taken to destroy network data in the rugged firewall of the OT device.
