Operational Technology (OT) is the backbone of Australia’s critical infrastructure — but it wasn’t built for today’s threat landscape. Legacy assets, blind spots, and rising cyber threats are placing industrial environments at risk of disruption, failure, and even physical harm. 

 This action plan provides a practical framework to help you: 

• Uncover and secure what’s really connected in your OT environment 

• Build toward compliance with frameworks like IEC 62443, NIST CSF or Essential Eight 

• Strengthen your cyber resilience from the ground up 

 Use it to benchmark your current state, identify critical gaps, and take meaningful steps toward improving security and operational reliability.
