Industrial networks are increasingly targeted by sophisticated cyber threats, making traditional perimeter-based security insufficient. Zero-trust architecture, recently highlighted in a CISA advisory as a key strategy for protecting critical infrastructure, assumes no implicit trust within or outside the network. This presentation explores the urgent need for zero-trust in industrial environments, focusing on two essential pillars: zero-trust segmentation—aligned with the IEC62443 zones and conduits model to control lateral movement—and zero-trust remote access, which enforces policy-driven, least-privilege connectivity for remote users. Attendees will learn a practical approach to implementing zero-trust easily and effectively, without disrupting industrial operations.
