Critical Infrastructure Cybersecurity in Australia
Expert SOCI Act compliance, CIRMP development, and security assessments for organisations that keep Australia's essential services running.
Assess Your Security PostureUnderstanding the SOCI Act
The Security of Critical Infrastructure Act 2018 (SOCI Act) establishes a framework for managing risks to Australia's critical infrastructure. Amended significantly in 2021 and 2022, the legislation now covers 11 sectors and imposes mandatory security obligations on entities that own or operate critical infrastructure assets.
The Act recognises that disruption to critical infrastructure can have cascading consequences across the economy, national security, and public safety. Whether you operate a power grid, a telecommunications network, a hospital system, or a data centre, the SOCI Act sets clear expectations for how you manage security risk.
Compliance is not optional. The Australian Government has made it clear that entities must take a proactive, all-hazards approach to protecting critical infrastructure assets, with enforcement mechanisms including civil penalties for non-compliance.
Key Obligations Under the SOCI Act
Positive Security Obligations (PSO)
All responsible entities must register their critical infrastructure assets and report cyber security incidents within mandated timeframes. These baseline obligations ensure the government maintains visibility of Australia's critical assets and can coordinate response efforts during incidents.
Critical Infrastructure Risk Management Program (CIRMP)
Designated entities must develop and maintain a written risk management program addressing four hazard vectors: cyber and information security, personnel security, supply chain security, and physical security. The CIRMP must be approved by the board or governing body and reviewed annually.
Mandatory Incident Reporting
Critical cyber security incidents must be reported to the Australian Signals Directorate within 12 hours. Other cyber security incidents that have a relevant impact on the asset must be reported within 72 hours. Timely reporting enables coordinated national response and intelligence sharing.
Systems of National Significance (SoNS)
Assets declared as Systems of National Significance face enhanced obligations including incident response planning, vulnerability assessments, system information provision, and the potential for government assistance during serious cyber incidents. These represent Australia's most strategically important assets.
Sectors We Support
Energy and Utilities
Electricity generation, transmission, and distribution networks face unique challenges in securing operational technology alongside IT systems. We help energy providers address both domains within their CIRMP obligations.
Communications
Telecommunications carriers and carriage service providers must protect infrastructure that millions of Australians depend on daily. Our assessments address the interconnected nature of communications networks and their cascading risk profile.
Financial Services
Banks, superannuation funds, and financial market infrastructure face overlapping obligations under the SOCI Act and APRA's CPS 234. We help financial entities align these frameworks to reduce duplication and strengthen overall security posture.
Transport
Aviation, maritime, and freight logistics networks increasingly rely on digital systems for safety and operations. We support transport operators in securing both their scheduling and control systems and the data that flows between them.
Health Care and Medical
Hospitals and health service providers manage sensitive patient data alongside life-critical medical devices and systems. Our assessments address the intersection of clinical systems, data protection, and SOCI Act compliance.
Data Storage and Processing
Data centres and cloud service providers that meet the SOCI Act thresholds must secure the infrastructure underpinning vast amounts of government and business data. We help data storage operators build security programs proportionate to their risk profile.
How Tech Blaze Supports Critical Infrastructure
CIRMP Development and Review
We help you build a Critical Infrastructure Risk Management Program that meets legislative requirements and is genuinely useful for managing risk. This includes identifying material risks across all four hazard vectors, mapping existing controls, and developing proportionate mitigation strategies.
Essential Eight for Critical Infrastructure
The Essential Eight provides a proven baseline for managing cyber risk. We conduct maturity assessments and develop uplift roadmaps that align your Essential Eight implementation with your broader CIRMP cyber security strategy. Read our guide on mapping Essential Eight to CIRMP requirements.
Risk Assessments
Our risk assessments go beyond checklists. We evaluate your threat landscape, identify material risks specific to your sector and asset profile, and provide actionable recommendations that your board and operational teams can implement.
Security Architecture Reviews
Critical infrastructure environments often span IT and OT domains with complex interconnections. We review your security architecture to identify gaps, validate network segmentation, and ensure your design supports both operational resilience and regulatory compliance.
vCISO Services
Not every critical infrastructure entity needs a full-time CISO. Our vCISO service provides senior security leadership on a fractional basis, giving you board-level guidance, security program oversight, and a trusted adviser who understands the SOCI Act landscape.
How We Have Helped
CIRMP Development for a Utility Provider
Developed a complete CIRMP for a regional utility provider covering all four hazard vectors. The program was approved by the board within eight weeks and included a practical implementation roadmap aligned with existing operational processes.
Essential Eight Uplift for a Health Sector Entity
Conducted an Essential Eight maturity assessment for a health services provider and delivered a prioritised uplift plan. The organisation achieved Maturity Level Two across all eight strategies within six months, directly supporting their CIRMP cyber security obligations.
Frequently Asked Questions
What is the SOCI Act and who does it apply to?
The Security of Critical Infrastructure Act 2018 imposes security obligations on owners and operators of critical infrastructure assets across 11 sectors including energy, communications, financial services, transport, health, data storage, food and grocery, higher education, space technology, water, and the defence industry.
What is a CIRMP and do I need one?
A Critical Infrastructure Risk Management Program is a written program that identifies material risks to your critical infrastructure asset and outlines strategies to manage them. CIRMPs are mandatory for designated entities and must address cyber security, personnel, supply chain, and physical security hazards.
How does the Essential Eight support SOCI Act compliance?
The Essential Eight is recognised as an industry-standard baseline for managing cyber risk in Australia. Implementing it supports the cyber and information security hazard vector within your CIRMP, demonstrating a reasonable and proportionate approach to managing cyber risks.
What are the incident reporting timeframes?
Critical cyber security incidents must be reported to the ASD within 12 hours. Other cyber security incidents with a relevant impact on the asset must be reported within 72 hours.
What is a System of National Significance?
A System of National Significance is a critical infrastructure asset declared by the Minister as being of the highest strategic importance. These entities face enhanced obligations including incident response planning, vulnerability assessments, and the potential for government assistance during serious cyber incidents.
Can Tech Blaze help if we are unsure whether the SOCI Act applies to us?
Yes. We can help you determine whether your assets fall within the SOCI Act definitions and, if so, which obligations apply. This includes assessing whether you need a CIRMP and what level of compliance is required for your specific circumstances.
