Protecting Critical Infrastructure with OT Cyber Controls

Cyberattacks on Australia’s critical infrastructure are no longer rare. They are frequent, targeted, and disruptive.

Recent incidents have shown how attackers are taking advantage of weak security systems. These include Industrial Control Systems (ICS) and Operational Technology (OT). Attacks may result in more than a simple fine or reputational damage. A single weakness can stop production, put lives at risk, or trigger a major safety event.

This is why OT cyber resilience has become a board-level priority. Leaders need more than a checklist. They need a clear view of their current security posture and a plan to close the gaps. RSM’s OT Cyber Security Controls Review, act as an independent “health check,”. Helping to identify where vulnerabilities exist and what steps will reduce risk.

What the Review Covers

The review checks your OT and ICS systems against standards and regulations. It helps find risks early and supports ways to improve security without affecting operations.

Key outcomes include:

• Identifying vulnerabilities and exposures that attackers could exploit
• Assessing risks to your most critical assets
• Enabling continuity planning so your business can recover quickly
• Supporting compliance with industry frameworks and legislation

Our team holds industry-recognised certifications and partners with leading OT cyber specialists. This means the insights you receive are practical, tested, and ready to act on.

Focus Areas

We look at two layers of controls: technical safeguards and governance processes.

By looking at both technology and management, the assessment gives a full picture of an organisation’s resilience. It covers system protection and how well an organisation responds and adapts.
