Protecting Australia's Critical Infrastructure:
An Overview of Sectors and Security Pillars

Understanding the Importance of Critical Infrastructure Protection

Critical infrastructure (CI) refers to the systems and assets, whether physical or virtual, that are essential to the functioning of our society and economy.


These systems and assets are considered vital because their disruption or destruction would have a significant impact on national security, public safety, and economic well-being.


The Australian Government has identified 11 critical infrastructure sectors, including communications, energy, transport, banking and finance, and water. The Security of Critical Infrastructure Act 2018 (SOCI Act) is aimed at ensuring the security and resilience of these sectors.

The Four Security Pillars of SOCI Act

The SOCI Act requires critical infrastructure entities to have measures in place to manage the risks associated with four security pillars: physical security, cyber security, personnel security, and supply chain security.


These pillars aim to protect the critical infrastructure assets from threats and ensure their continued operation. Physical security focuses on protecting the physical assets of the infrastructure, such as buildings, equipment, and other facilities.


Cybersecurity focuses on protecting the infrastructure's electronic and digital systems and data from unauthorized access, theft, or damage.


Personnel security aims to ensure that individuals working in critical infrastructure are trustworthy and have the appropriate security clearance. Supply chain security involves managing and securing the complex supply chains that support critical infrastructure operations.


At Excelium, we provide specialized expertise in each of these security pillars to help critical infrastructure entities comply with SOCI Act requirements and safeguard their operations.

Partner with Excelium for fair, effective and secure critical infrastructure protection solutions

The Australian government defines critical infrastructure as the physical and information technology assets, systems, networks, and processes that are essential to the economic and social well-being of the nation. Critical infrastructure sectors in Australia include communications, energy, finance, food and grocery, health, transport, and water.


The recent reforms to the Security of Critical Infrastructure Act aim to strengthen the resilience of Australia's critical infrastructure and protect it from cyber threats and foreign interference. Compliance with the Act's requirements is mandatory for critical infrastructure entities, and failure to comply can result in significant penalties. Consultation with an expert like Excelium is crucial for organizations affected by these reforms to ensure compliance and maintain business continuity.
