ICONIC 2025 | Securing Identities in Complex OT Environments

Speaker: Stephen Mathezer, Vice President, Service Delivery & Innovation

Event: iCONIC 2025 | June 5, 2025

Stephen Mathezer explores the challenges of securing identities in industrial control systems (ICS) and operational technology (OT) environments, where traditional IT security models often fall short. He emphasizes the need for a Zero Trust approach tailored to the unique constraints of OT, including legacy systems, limited authentication, and low cybersecurity maturity.

The session introduces five critical controls for ICS security and outlines common vulnerabilities such as remote access, poor segmentation, and insufficient monitoring. Stephen walks through the NIST 800-207 Zero Trust Architecture and its core tenets, positioning identity as the central control point in OT environments.
