Building resilience through regulation
Australia’s essential services — from power and water to transport, health and communications — form the backbone of our national resilience. But as these systems become increasingly digital and interconnected, they’ve also become more vulnerable to cyber disruption and attack.
The Security of Critical Infrastructure (SOCI) Act is the Australian Government’s legislative framework designed to address that challenge. It recognises that protecting the nation’s critical assets isn’t just a matter of compliance — it’s a matter of continuity, safety, and trust.
For organisations operating complex Operational Technology (OT) environments, understanding and acting on the SOCI requirements is now fundamental to maintaining both compliance and operational resilience. Orro helps leaders translate these obligations into practical steps that strengthen security across their OT networks.
What the SOCI Act is — and why it exists
Originally introduced in 2018 and significantly expanded in 2021–2022, the SOCI Act establishes a national framework for identifying, protecting, and managing risks to critical infrastructure.
Its purpose is simple: to safeguard the assets and systems that underpin Australia’s security, economy, and community wellbeing. The Act covers 11 key sectors, including energy, communications, transport, water, healthcare, food and grocery, higher education, data storage and processing, and space technology.
These reforms were prompted by escalating threats — from state-sponsored actors and ransomware groups to supply-chain vulnerabilities — that could disrupt essential services or compromise sensitive data. By introducing clearer accountability, reporting and collaboration mechanisms, the government aims to lift baseline resilience across the nation’s most important industries.

Key obligations for organisations
The SOCI Act places several core obligations on owners and operators of “critical infrastructure assets.” While the exact requirements depend on asset type and designation, the following pillars apply broadly across most sectors:
1. Critical Infrastructure Asset Registration
Organisations must register relevant assets with the Cyber and Infrastructure Security Centre (CISC). This creates a national picture of who owns, operates and controls critical systems — an essential foundation for coordinated protection and response.
2. Mandatory Cyber Incident Reporting
Entities must report cyber incidents that impact the availability, confidentiality or integrity of their critical infrastructure. Significant incidents must be reported within 12 hours if they cause major operational disruption, and within 72 hours for other material impacts.
This enables government agencies such as the Australian Cyber Security Centre (ACSC) to provide timely assistance and situational awareness.
3. Risk Management Program (RMP)
Designated “responsible entities” are required to implement and maintain a comprehensive Risk Management Program that identifies, mitigates and manages material risks across four key domains: cyber and information security, physical security, personnel security, and supply chain.
The program must be documented, reviewed annually, and signed off by the board or accountable executive.
4. Government Assistance and Intervention Powers
In exceptional circumstances, the Act grants the government powers to intervene — for example, to direct or assist an organisation in responding to a serious cyber incident threatening national security or public safety. These powers are intended as a last resort and are exercised only when collaboration fails or the threat exceeds an organisation’s capability.

Why OT systems sit at the centre
For many critical infrastructure operators, the systems that most directly enable their services — energy grids, control systems, SCADA, industrial automation and safety platforms — fall squarely within the OT domain.
These systems were often designed decades ago for reliability and uptime, not for cybersecurity. As a result, many OT environments still rely on legacy protocols, lack basic visibility, and can’t be easily patched without risking operational disruption.
That makes OT networks both essential and exposed. The SOCI Act’s emphasis on risk management and incident reporting directly intersects with these challenges: you can’t secure what you can’t see.
Organisations need integrated visibility across IT and OT, secure segmentation between business and operational networks, and continuous monitoring to detect anomalies before they become incidents.
Orro’s approach focuses on bridging that divide — combining real-time threat detection, network intelligence and managed response to help operators meet compliance obligations while protecting uptime and safety.
From compliance to resilience
Meeting the letter of the law is only part of the journey. True resilience comes from embedding security into everyday operations — from asset discovery and access control through to continuous monitoring and incident response.
For OT leaders, this means moving beyond viewing the SOCI Act as a checklist, and instead treating it as an opportunity to uplift operational maturity. When done well, compliance and resilience reinforce each other: visibility reduces risk, governance drives accountability, and proactive monitoring ensures business continuity.
At Orro, we help critical infrastructure organisations take practical steps that align regulatory expectations with operational realities — translating complex compliance into tangible outcomes for secure, resilient operations.
Staying ahead
The SOCI Act represents a significant shift in how Australia protects its critical infrastructure — but it also provides a clear path forward. By building visibility, strengthening control, and engaging trusted partners, organisations can meet their obligations while improving their ability to withstand and recover from disruption.
