In Australia’s National Interest - Security of Critical Infrastructure

• Building Assurance: A Framework for Risk-Based Supply Chain Mapping and Categorisation

  In this episode, we unpack one of the most critical challenges facing Australia’s essential services: understanding and managing the risks hidden within complex supply chains. Modern critical infrastructure depends on long, interconnected, and often opaque networks of suppliers — and under the Security of Critical Infrastructure Act 2018, these dependencies are now a regulated security obligation.Drawing on Pentagram Advisory’s Eight-Step Risk-Based Supply Chain Mapping and Categorisation Framework, we explore how organisations can move beyond tick-box compliance and build a defensible, intelligence-led approach to supplier assurance.From governance and threat analysis to mapping, tiering, and continuous monitoring, this episode breaks down each step in practical terms for boards, senior executives, and security practitioners.You’ll hear how the right framework can transform supplier oversight from a procurement activity into a core protective security function — strengthening resilience, reducing over-reliance, and giving decision-makers a clear line of sight into vulnerabilities across every tier of the supply chain.Whether you work in energy, water, transport, telecommunications, or any sector covered by the SOCI Act, this episode provides essential insights for building assurance in an increasingly interconnected and risk-exposed environment.A supply chain is only as strong as the weakest link you can see.Tune in to learn how to make those links visible, verifiable, and secure.

• When Trust Breaks, Free Will Decides: How the Psychological Contract Shapes Insider Threat and Cyber Security Compliance

  Why do employees sometimes go above and beyond to protect their organisation — and other times bend rules, ignore policies, or disengage from security altogether?In this episode, Pentagram Advisory explores the role of the psychological contract — the unwritten expectations of trust and fairness between employer and employee — and how its breakdown fuels insider threats. Drawing on research from the University of Warwick, we unpack why technical controls alone aren’t enough, how to recognise early signs of a breach, and what leaders can do to repair trust before it escalates into a security risk.For leaders, executives, and practitioners, this is a reminder that the deciding factor in insider threat is rarely opportunity — it is choice. And choice is shaped by trust.
