OT Security in transition: remote operations, supply chain, regulation, and AI – what needs to be done now

The ongoing convergence of IT and OT systems is fundamentally changing the risk landscape. Remote operations, cloud connections and third parties are broadening the attack surface, while resilience is becoming the key protection goal. 

The PAC trend study analyses how governance models, standards and technical measures are implemented in sectors with high availability requirements and strict regulations – such as manufacturing, health, utilities and transport. It demonstrates practical and targeted ways to manage OT security, prioritise risks and ensure operational security in the long term. 

• Reality check: facts and context on new risk drivers in networked IT/OT systems.
• Practical applications in four sectors:  insights from manufacturing, health, utilities and transportation.
• Focus on remote access: how external access and maintenance interfaces increase the attack surface.  
• Governance and regulation:  importance of NIS 2, ISO 27001/27002 and IEC 62443 for OT security and operational resilience.  
• Reliability:  clear priorities, roadmap and recommendations for robust resilience.
