Network Segmentation vs Operational Simplicity
Network segmentation should reduce cyber risk without creating unnecessary operational complexity. RegulatoryTRIZ resolves this contradiction by applying segmentation proportionally to business risk.

Regulations
Business Context
Network segmentation limits the spread of cyberattacks by separating critical systems, business applications, operational technology, and user environments. While segmentation significantly improves resilience, it also increases network complexity, administration, and operational maintenance.
Conflict
Greater segmentation improves security but increases operational complexity. Simpler architectures improve efficiency but increase the potential impact of cyber incidents.
Regulatory Obligations
Protect critical networks
Separate high-risk environments
Review network architecture regularly
Monitor network security continuously
Document segmentation controls
Risks
Higher administration effort
Increased infrastructure complexity
Weak network protection
Increased cyber exposure
Recommended Controls
Apply risk-based segmentation focusing on critical assets rather than every system. Regular architecture reviews should balance operational simplicity with effective containment of cyber threats.
