What CISOs need to tell the board about zero trust in OT: A 90-day communication and action plan
Summary
This article discusses the challenges CISOs face in communicating zero trust implementation within Operational Technology (OT) environments to their boards, especially in the wake of incidents like the Colonial Pipeline attack. It highlights the misalignment between traditional IT-centric zero trust models and the unique realities of critical OT infrastructure, which often involves older equipment requiring 24/7 uptime. The author emphasizes the need for CISOs to provide a clear, actionable communication and action plan to address regulatory compliance (e.g., TSA directives, NERC CIP) and bridge the gap between board expectations and practical OT security application.
IFF Assessment

Defender Context
Defenders, particularly those in critical infrastructure sectors, need to understand how to adapt IT-focused security frameworks like zero trust to the unique constraints and operational requirements of OT environments. This article highlights the importance of effective communication with executive leadership and boards, translating complex security strategies into actionable plans that address both compliance demands and operational realities. It underscores a continuous trend of regulatory pressure on critical infrastructure to enhance cybersecurity postures, making a clear zero-trust roadmap essential.
