4. Industry Best Practices for Successful Convergence Achieving successful IT/OT convergence extends beyond mere technological integration; it demands a holistic approach encompassing strategic organizational alignment, adherence to robust cybersecurity frameworks, effective data management, and proactive skill development. Strategic Organizational Alignment and Target Operating Models A successful digital transformation fundamentally requires a reconceptualization of existing operating models. 2 This necessitates the development of a Target Operating Model (TOM) that defines the transformation strategy and outlines future requirements for organizational structures and processes within both IT and OT departments. 2 Key elements of this strategic alignment include: Clear View on Application Landscape: Organizations need to achieve a clear view of their total applications landscape. This is a crucial step in IT/OT convergence, as it helps to lower and minimize the risk of mal...

3. Hybrid Architectural Models for Seamless Integration To effectively bridge the IT and OT domains, organizations are adopting and evolving various hybrid architectural models. These models aim to balance the need for real-time operational control with the demands of enterprise-level data processing and analytics, all while maintaining robust security. The Foundational Purdue Enterprise Reference Architecture and its Modern Adaptations The Purdue Model for ICS Security serves as a foundational framework for organizing industrial control systems into distinct layers, separating OT from IT. 10 Its original purpose was to manage communication between systems by isolating different functions across layers and implementing network segmentation, thereby reducing the attack surface by isolating critical industrial processes from less secure IT networks. 11 The model segments the network into six hierarchical levels, from 0 to 5, with Levels 0-3 representing the OT side and Levels...
