Protecting the Australian grid against cyber attacks

Australia is constantly moving towards the development of smart grids with a key focus on ensuring reliability, efficiency, and sustainability. Ever-increasing electricity demand, energy security, de-carbonization, renewable energy integration, climate change events, integration of AI and IoT devices, and technological innovations are accelerating this transition towards smart grids. This development of digital technologies, smart grids, microgrids, and internet connectivity is expanding the impact and scale of cyber security threats for power networks in Australia. Australia’s energy markets and power sector has been targeted by cyber security attacks in the past and the Australian government is actively gearing up to address this challenge by developing regulations and policies, collaborating with industry players, and creating public awareness about cybersecurity solutions.

On 27th Nov 2021, Queensland energy company, CS Energy suffered cybersecurity on its ICT network, which includes the systems used by state power grid operator, Powerlink Queensland. Although this attack did not cause any disruption in the power network, this shows the potential cybersecurity threat to the Australian power grid. This is just one example of a cybersecurity attack on the power network of one of the most prominent states in Australia. It will depend on Australia’s capability to face such cybersecurity crimes head-on and protect confidential consumer databases, and government information and defend the grid against such threats.

Australian Government is focusing on following three key dimensions to strengthen its capabilities against such espionage attempts on the power grid.

Developing cybersecurity awareness in public:

The Australian government is committed to raising awareness in the public about cybersecurity threats. Stay Smart Online is a government website providing guidelines to Australians about securing smart devices at homes & businesses, avoiding scams and phishing, and protecting themselves against online cybercrimes. Cybersecurity awareness week is an annual event which is dedicated to promoting online safe practices and providing security tips to the public to protect against the latest cybersecurity challenges. This event is organized by Australian Cyber Security Centre (ACSC), in collaboration with a range of government, industry, and community partners. The  event generally takes place in October every year. This event contains seminars, workshops, and interactions with experts and industry partners in the domain of cybersecurity.

Collaboration with international partners:

Australia is a member of The Five Eyes alliance, which is a partnership between the intelligence agencies of 5 most advanced nations in the world i.e., Australia, Canada, New Zealand, the UK, and the U.S. This alliance focuses on sharing intelligence, collaborating, and mitigating cybersecurity challenges across the globe, especially in the member nations. The Australia-US Cyber Security Dialogue is another initiative by the Australian government to strengthen collaboration between U.S. and Australia on cybersecurity challenges.

Strengthening legislation for cybersecurity of critical grid infrastructure:

Following are some of the key legislations that are contributing to strengthening the cybersecurity measures in Australia:
a. The Security of Critical Infrastructure Act 2018 establishes the framework for managing security risks to critical infrastructure, such as the power grid.
b. Australian Signals Directorate (ASD) Act 2018 created the ASD as an independent agency within the Department of Defense, which is responsible for providing cybersecurity advice to government agencies and critical infrastructure.
c. The Security of Critical Infrastructure Act 2018 facilitated the establishment of a framework for managing security risks to critical infrastructure.

Major OEMs, Companies & Startups contributing to strengthening Cybersecurity Solutions in Australia:

Cybersecurity poses an immense challenge for the power grid that leads to business opportunities for several companies and startups. Following are some of the companies that are contributing to building up defense against cybercrimes in Australia.
