Key Takeaway

A single untrained employee can expose an entire organisation. The NSW Reconstruction Authority breach was not a sophisticated cyber attack — it was a well-intentioned staff member trying to do their job faster. Without training, policy, and technical controls, this scenario will repeat across every government agency.

Control Mapping Exercise

Select a control for each step, then check your answers.

Defence in Depth

No single control prevents all shadow AI risks. Effective protection requires layered defences: policy sets the rules, training builds awareness, technical controls enforce boundaries, and monitoring catches what slips through. Each layer compensates for the weaknesses of the others.
