Security Threats from OT/IT Convergence
Smart factories face new cybersecurity threats as OT (Operational Technology) and IT networks become interconnected. When manufacturing equipment is connected to the internet, risks such as ransomware and industrial espionage emerge.
Major Threat Types
Security Architecture Design
Network Segmentation
Physically and logically separate OT and IT networks, transmitting only necessary data through a DMZ.
Industrial Firewalls
Detect abnormal traffic in industrial protocols (Modbus, OPC-UA) using OT-specific firewalls.
Access Control
Manage per-equipment access permissions based on the principle of least privilege.
Response Framework
Conclusion
Smart factory security is not optional but essential. POLYGLOTSOFT supports the design of security architectures optimized for OT/IT converged environments.
