Network Segmentation vs System Integration
Define IEC 62443 security zones with controlled conduits—firewalls, data diodes, and DMZs—to enforce segmentation without breaking required data flows.

Regulations
Business Context
Network segmentation limits the spread of cyberattacks by separating
operational zones. Greater segmentation, however, may complicate
communications between industrial systems that require continuous
information exchange.
The Contradiction
Greater segmentation improves cybersecurity.
Greater integration improves operational efficiency.
Why It Exists
Industrial systems rely on data sharing, while cybersecurity requires
limiting unnecessary network connectivity.
Direction
Implement secure industrial zones connected through firewalls, data
diodes, and tightly controlled communication gateways.
