From Technical Controls to Team Culture: Quantifying Human Behavior in Cyber Security

We have invited Jay to present his brilliant LAST Conf Melb 2025 session as part of the Signal Not Noise online series.

In a digital landscape constantly shifting, the front line of cyber security resides not solely in the data centers, but increasingly with every employee. Despite Australian organizations investing heavily in cybersecurity measures (globally, losses exceed $1 trillion annually), a significant percentage of cyber incidents—approximately 38%—result from human errors or actions. This critical contradiction highlights a failure in conventional security strategy: the neglect of human factors.

This session addresses how organizations can shift their focus from purely technological controls to adopting a holistic, human-centered security approach. It is argued that treating people like "machines" with a binary zero or one state is a fundamental flaw, ignoring the complex and unique digital behaviours of individuals. Drawing on decades of research in behavioural science, psychology, and cognitive engineering, we introduce a method to characterise and quantify human risk.

Dr. Jay Jeong is a  leading cybersecurity expert and researcher with a focus on the human-centric aspects of digital security. He is also the managing director of the Australian cybersecurity company TNK.
