Cybersecurity vs Connectivity
Apply IEC 62443 zone-and-conduit segmentation at design stage so connectivity and security requirements are resolved architecturally, not retrofitted.

Business Context
Connected industrial systems improve remote support, analytics, monitoring, optimization, and enterprise integration. Increasing connectivity also expands the potential pathways through which unauthorized access, malware, or compromised systems can affect industrial operations.
Green Field Industrial Projects TRIZ Resolution
Separate connectivity according to function, trust level, and operational consequence. Use segmented architectures, controlled gateways, authenticated access, monitored interfaces, and isolated critical functions rather than choosing between unrestricted connectivity and complete isolation.
Applicable TRIZ Principles
Principle 1 – Segmentation separates networks and systems according to security requirements.
Principle 2 – Taking Out isolates critical functions from unnecessary external exposure.
Principle 24 – Intermediary uses controlled gateways between systems with different trust levels.
Expected Outcome
Preserved digital connectivity
Reduced cyber exposure
Better control of external access
Greater operational resilience
Decision Indicators
Early indicators include:
Critical control systems have unnecessary network exposure.
Remote access bypasses standardized security controls.
Cybersecurity requirements prevent useful operational integration.
Network architecture lacks clear trust boundaries.
New connections are added without evaluating operational consequence.
