Critical Infrastructure Security Services Australia
Australia’s critical infrastructure is a high-value target for state-sponsored actors. Intrix helps operators meet their SOCI Act obligations, secure OT/ICS environments, and defend against sophisticated nation-state threats.
Operating in a High-Stakes Environment
Australia’s critical infrastructure is a high-value target for state-sponsored actors conducting espionage and pre-positioning for future disruption. The threat is persistent, sophisticated, and of national importance.
In response, the government has expanded the Security of Critical Infrastructure (SOCI) Act 2018, which imposes specific legal obligations on critical infrastructure operators.
Key SOCI Act Obligations
You must maintain a risk program covering cyber, physical, personnel, and supply chain threats
Incident Reporting
You are mandated to report significant cyber incidents to the government within strict timeframes, ensuring national visibility of threats
Enhanced Security Obligations
You may receive threat-based directives that require fast implementation of extra security measures

What is cybersecurity governance?
Cybersecurity governance is the set of processes, structures, and accountability mechanisms that align an organisation’s security activities with its business objectives and regulatory obligations. It defines who is responsible for security decisions, how risk is managed, and how compliance is demonstrated. Intrix helps Australian organisations build governance frameworks aligned with ISO 27001, NIST CSF, and COBIT.
What cybersecurity policies does my organisation need?
Most Australian organisations require at minimum an Acceptable Use Policy, Access Control Policy, Data Security Policy, Incident Response Policy, Remote Work Policy, and Third-Party Risk Management Policy. The specific policies required depend on your industry, regulatory obligations, and the frameworks you are implementing. Intrix conducts a needs analysis to determine which policies are required and drafts them to be practical and enforceable.
How do I choose between ISO 27001, NIST CSF, and COBIT?
ISO 27001 is the internationally recognised standard for information security management systems and suits organisations seeking formal certification. NIST CSF is a flexible risk-based framework developed by the US National Institute of Standards and Technology that works well as an internal governance tool without requiring certification. COBIT focuses on IT governance and aligns security with business goals. Intrix helps organisations select the right framework based on their regulatory environment, customer requirements, and maturity level.
How long does it take to develop cybersecurity policies?
Developing a complete suite of cybersecurity policies for an Australian organisation typically takes four to eight weeks depending on the number of policies required, the complexity of the business, and how quickly stakeholders can review and approve drafts. Intrix follows a structured process covering needs analysis, policy drafting, standards alignment, and procedure development to keep the engagement on track.
