Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices, particularly in Industrial Control Systems and SCADA systems, are increasingly vulnerable to cyber-attacks due to connectivity through public networks, with legacy systems not designed to resist such threats and often unable to be upgraded or patched, posing significant risks to mission-critical systems.
Innovation Solution
A method and system for assessing vulnerability and penetration potential of IoT devices that use a single tool capable of adapting to various communication protocols and environments, performing vulnerability scans without installing software or hardware on the devices, and integrating penetration testing to identify cybersecurity risks before they materialize, utilizing wireless and wired communication mediums and software-defined radio technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IoT devices are connected through public networks to enable data transfer and remote management, then connectivity and operational flexibility are improved, but vulnerability to cyber-attacks and security risks increase
Solution Approach 1:
The system performs preliminary vulnerability assessment and penetration testing before actual cyber-attacks can occur. By proactively identifying security weaknesses in IoT devices through automated scanning and testing mechanisms, the system enables preventive security measures to be implemented before vulnerabilities are exploited by malicious actors.
Solution Approach 2:
The system establishes continuous feedback loops through repeated vulnerability assessments and security monitoring. The automated system continuously scans IoT devices, evaluates security posture, and provides feedback that enables ongoing security improvements and rapid response to newly discovered vulnerabilities in connected devices.
2Object-affected harmful factors
If legacy ICS/SCADA systems are upgraded or patched to address security vulnerabilities, then security resistance is improved, but system compatibility and operational continuity may deteriorate
Solution Approach 1:
The vulnerability assessment system acts as an intermediary that evaluates security needs without requiring direct modification of legacy systems. By providing detailed security assessments and recommendations, the system enables security improvements to be implemented through controlled, targeted interventions rather than forced upgrades that could disrupt legacy ICS/SCADA operations.
Solution Approach 2:
The system enables selective parameter changes by identifying specific vulnerabilities and recommending targeted security configurations or parameter adjustments rather than comprehensive system upgrades. This allows security improvements to be implemented by modifying only necessary parameters while preserving the overall stability and compatibility of legacy systems.
3Adaptability or versatility
If multiple specialized tools are used to assess different types of IoT devices and communication protocols, then assessment comprehensiveness is improved, but system complexity and operational difficulty increase
Solution Approach 1:
The system implements a universal vulnerability assessment platform that can evaluate multiple types of IoT devices across different communication protocols through a single integrated tool. The system automatically detects device types, selects appropriate assessment methodologies, and adapts testing parameters based on the target device, eliminating the need for operators to manually select and configure multiple specialized tools.
Solution Approach 2:
The system performs self-service by automatically identifying IoT devices, determining their communication protocols, and selecting appropriate vulnerability assessment methods without requiring external configuration or multiple specialized tools. The automated system adapts its assessment approach based on detected device characteristics, reducing operational complexity while maintaining comprehensive coverage.
4Measurement precision
If vulnerability assessment tools install software or hardware on IoT devices for testing, then assessment accuracy is improved, but device integrity and operational risk increase
Solution Approach 1:
The system introduces an intermediary assessment approach that evaluates vulnerabilities through external observation and analysis rather than direct installation on target devices. By using non-intrusive scanning and testing methods that monitor device responses without modifying device software or hardware, the system maintains device integrity while still achieving comprehensive vulnerability detection.
