In this episode, ASPI’s Alex Caples speaks with Hamish Hansford, who was recently appointed deputy secretary of cyber and infrastructure security at the Department of Home Affairs. They discuss the links between cybersecurity, supply-chain security and critical infrastructure, as well as the rise in ransomware attacks, including on hospitals, and lessons learned from the Colonial Pipeline attack. They also talk about the amendments to the Security of Critical Infrastructure Act and what they mean for industry, and the role that government and industry need to play in securing Australia’s critical infrastructure.
