Regulations
Business Context
Integrated industrial networks improve operational visibility and
centralized management across multiple facilities.
The Contradiction
Greater connectivity improves operational efficiency.
Greater segmentation improves cybersecurity.
Why It Exists
Highly connected networks increase the possibility of lateral movement
during a cyberattack.
Direction
Use segmented industrial architectures with secure gateways and
controlled information exchange between network zones.
