A Value-Driven Framework for OT Security in Corporate Spin-Offs

Abstract

Corporate spin-offs involving Operational Technology (OT) assets present complex challenges where cybersecurity must evolve from a supporting function into a foundational element of operational continuity. The Cyber Factory Model provides a structured framework to address the unique vulnerabilities of OT environments during corporate separations, where availability often outweighs confidentiality and integrity priorities. It integrates four strategic principles—prioritized risk reduction, integrated capability deployment, standardization for velocity, and operational independence by Day One—into a phased execution process encompassing site assessment, control prioritization, validation, and handover. Through systematic architectural scaffolding and embedded capabilities such as identity management rationalization, network segmentation redesign, asset visibility enhancement, and threat detection implementation, the model enables separated entities to establish secure, autonomous operations within Transitional Service Agreement (TSA) timelines. By embedding security into asset transfer activities rather than treating it as a parallel workstream, organizations can avoid inherited technical debt, reduce post-separation remediation costs, and build resilient foundations for future modernization. The framework redefines OT security—transforming what was once a separation barrier into a pathway for strategic value—positioning newly independent entities to sustain uninterrupted operations and defend against emerging industrial threats.
