Combining Safety Regulations and Cyber Defense in Industrial Operations
The convergence of Operational Technology (OT) and Information Technology (IT) in industrial control systems is a significant trend, offering a unified view of industrial automation control systems. However, this convergence brings challenges, particularly in terms of safety and security. Here are some best practices for achieving a seamless integration of OT and IT.
Unified Data Management
A key aspect of IT/OT convergence is effective data management. This involves implementing a unified namespace (UNS) to structure and manage OT data effectively, and using data products to turn this data into reusable business assets. Robust data governance frameworks should be established to ensure data quality, consistency, privacy, and regulatory compliance.
Cybersecurity Strategies
Cybersecurity is paramount in the converged IT/OT environment. Thorough risk assessments should be conducted to identify potential vulnerabilities, and comprehensive mitigation strategies should be implemented to manage these risks. A zero-trust policy should be applied to ensure that all connections are verified, reducing the risk of unauthorized access and cyber threats. Regular security assessments are crucial for maintaining a secure environment.
Technical Integration
Technical integration is another crucial aspect of IT/OT convergence. Platforms that facilitate the integration of legacy OT systems with modern IT infrastructure should be used. Real-time communication requirements, critical for OT systems, should be supported by the integration solutions. Technologies like MQTT, OPC UA, and Apache Kafka can help bridge the gap between different systems.
Organizational and Cultural Change
The successful integration of OT and IT requires a cultural shift. Cross-functional collaboration between IT and OT teams should be encouraged, with training programs to enhance skills in both domains and promote a data-driven decision-making culture. Organizational change management strategies should be implemented to overcome resistance and ensure that both teams work towards shared goals.
Safety and Compliance
Safety and compliance are essential in IT/OT convergence. The safety and availability of OT systems should be prioritized, ensuring that any integration does not compromise these critical functions. Safety standards and protocols should be implemented to safeguard against potential disruptions. Regulatory compliance should also be ensured, with records of changes maintained and systems made auditable.
By following these best practices, industrial organizations can effectively integrate OT and IT safety and security, improving overall operational efficiency while minimizing risks. In the increasingly interconnected world, these practices are essential for ensuring the safety and security of industrial control systems.

Control systems in the context of IT/OT convergence should be reinforced with cybersecurity measures, such as conducting regular risk assessments, implementing comprehensive mitigation strategies, and applying a zero-trust policy for secure connections.
The successful integration of industrial automation control systems demands a unified data management strategy, which includes the implementation of a unified namespace, data governance frameworks for data quality and privacy, and the use of data products to convert OT data into business assets.
