Fortifying the cyber security of mission critical industrial and communication networks

Comprehensive Approach to fortifying the Cybersecurity of Mission Critical Industrial Communication Networks:

As the Australian Critical infrastructure industry continues to evolve, cybersecurity resilience of critical infrastructure has become a national priority. With the expansion of the Security of Critical Infrastructure (SOCI) Act, alongside guidance from the Australian Cyber Security Centre (ACSC) and the Essential Eight maturity model, operators of essential critical services face increasing pressure to adopt a holistic cybersecurity approach that addresses both emerging threats and compliance obligations.

This presentation outlines a comprehensive, defence-in-depth strategy for enhancing the cybersecurity posture of mission critical industrial and interconnected communication networks within Australia’s critical sectors. It will examine how escalating threats from nation-state actors, advanced persistent threats (APTs), and hybrid cyber-physical attacks are reshaping risk management frameworks and pushing asset owners to strengthen both technical and organisational controls.

Key components of this approach include:

The session will also address unique Australian challenges based on real-world insights from industry experts and lessons learned from recent incidents.

By presenting actionable strategies that balance cybersecurity with operational continuity, this presentation contributes to the ongoing conversation around safeguarding Australia's most vital systems —power, water, transport, telecommunications, and beyond — against today’s most sophisticated adversaries.
