Secure AI Integration in OT Systems: Key Principles and Best Practices

Redazione RHC 04/12/2025

Since ChatGPT’s public release in November 2022, artificial intelligence (AI) has been integrated into many aspects of human society. For owners and operators of critical infrastructure, AI can be used to increase efficiency and productivity, improve decision-making, reduce costs, and enhance customer experience. Despite its many benefits, integrating AI into operational technology (OT) environments that manage essential public services also introduces significant risks —such as OT process model drift over time or security process circumvention—that owners and operators must carefully manage to ensure the availability and reliability of critical infrastructure. The Australian Signals Directorate, through the Australian Cyber Security Centre, together with
