The Cyber Brief

Former Prime Minister Malcolm Turnbull joins Valeska and co-host Dominic Anderson for the first of a two-part discussion about cybersecurity as national security in Australia. As the 29th Prime Minister of Australia, a former lawyer, technologist, and now backer of some of the most interesting cyber companies worldwide, Malcolm brings a perspective on cybersecurity shaped by experience on every side of the problem. In this episode, Malcolm shares his views on Australia's cyber strategy, offensive cyber capabilities, escalation risk in cyber conflict, the future of Five Eyes cooperation, and whether Australia can build a genuinely sovereign cyber capability.

Valeska and co-host David Rountree speak with Lieutenant General Michelle McGuinness CSC, Australia's National Cyber Security Coordinator and leader of the National Office of Cyber Security (NOCS). Michelle dives in regarding the role of NOCS, and how it approaches government coordination and consequence management during major incidents. When and how should organisations engage with government during an incident? What's best practice for incident communications? How does NOCS work with industry, regulators and other government agencies? How are organisations engaging with Australia's limited use and ransomware payment reporting regimes? Michelle also shares her approach to leadership, the importance of empathy when working with organisations under pressure, and how her military background has shaped her leadership approach.
