Explanation

Use segmentation: Network segmentation is critical in an OT environment to isolate different ICS (Industrial Control System) networks and protect sensitive systems. This limits the spread of threats and provides controlled access between segments. Deploy a FortiGate device within each ICS network: Deploying FortiGate devices in each ICS network ensures that localized security measures are in place to detect and prevent unauthorized access or threats. Configure firewall policies with industrial protocol sensors: Configuring policies with industrial protocol sensors helps monitor and protect OT-specific traffic (e.g., Modbus, DNP3). This enables the FortiGate to detect and respond to malicious activities targeting OT protocols.
