OT Segmentation Gaps Leave Infrastructure Open to Cyber Threats

The article discusses the challenges of operational technology (OT) security, particularly emphasizing the importance of network segmentation to protect against cyber threats. While segmentation strategies are recommended, their effectiveness depends on operators' awareness of risks and threats. There are concerns with both traditional and microsegmentation models, as they can often break down due to user convenience and vendor overpromises.

The piece highlights the need for ongoing management of segmentation rather than treating it as a one-time project. It calls out the importance of using zero trust principles and proactive monitoring to adapt segmentation strategies effectively within OT environments.
