Kevin Sheu of Moxa, explains why OT cybersecurity requires a network-focused approach and how segmentation and defense-in-depth help reduce risk where endpoint protection is limited.
Operational technology environments face rising cyber risk as industrial systems connect more tightly with enterprise networks, cloud platforms and remote operations. Legacy devices, proprietary protocols and strict uptime requirements limit the effectiveness of traditional endpoint security, creating visibility gaps across control and edge layers. These conditions increase exposure to ransomware, lateral movement and unauthorized access, particularly where encryption and authentication are not native to OT communications.
Kevin Sheu, senior OT consultant at Moxa, explains why OT cybersecurity demands a network-first approach rather than direct endpoint control. He outlines how segmentation, industrial firewalls and defense-in-depth architectures help contain threats, improve detection and support resilience without disrupting operations.
In this session, Sheu will also discuss:
- Why IT-centric security models fall short in OT environments with legacy devices and protocol constraints;
- How network segmentation and industrial firewalls reduce blast radius and improve visibility;
- What architecture patterns support resilient OT operations without impacting uptime.
