Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional penetration testing and live network testing are used to assess vulnerability, then assessment accuracy is improved, but risk to critical equipment and infrastructure increases
Solution Approach 1:
The patent creates a digital twin (virtual replica) of the OT network that includes all assets, communication pathways, security controls, and vulnerabilities. This copy allows penetration testing and vulnerability assessment to be performed on the virtual model rather than the actual production network, thereby maintaining assessment accuracy while eliminating risk to critical equipment and infrastructure
Solution Approach 2:
The digital twin serves as an intermediary between the vulnerability assessment process and the actual OT network. By performing all testing and analysis on this intermediate virtual representation, the system enables accurate security evaluation without direct interaction with or potential harm to the production environment
2Measurement precision
If point-in-time vulnerability assessments are performed, then risk exposure is captured, but the utility is limited by historical snapshot nature
Solution Approach 1:
The system continuously updates the digital twin as changes are detected in the OT network environment. Rather than performing discrete point-in-time assessments, the vulnerability assessment operates continuously, maintaining an up-to-date virtual representation that reflects current network state, thereby eliminating the timeliness limitation of historical snapshots
Solution Approach 2:
The system implements continuous monitoring that detects changes in the OT network and automatically updates the digital twin accordingly. This feedback loop ensures the virtual model remains synchronized with the actual network, providing continuously current vulnerability information rather than stale historical data
3Adaptability or versatility
If OT networks become larger and more connected to improve functionality, then operational capability is enhanced, but exposure to vulnerabilities increases
Solution Approach 1:
The digital twin accurately replicates the entire expanded OT network including all assets, connections, and vulnerabilities. This virtual copy enables comprehensive security analysis of the large, complex network without requiring physical access or risking the actual infrastructure, thereby allowing functionality expansion while managing vulnerability exposure through virtual testing
Solution Approach 2:
The system segments the large OT network into individual assets and communication pathways that are separately represented in the digital twin. This segmentation allows for granular vulnerability assessment and targeted security analysis of specific network components, making it easier to manage and mitigate vulnerabilities in large-scale environments
