About the Australian Cyber Security Centre

The Australian Cyber Security Centre is the Australian Government’s lead on national cyber security. It brings together cyber security capabilities from across the Australian Government to improve the cyber resilience of the Australian community and support the economic and social prosperity of Australia in the digital age.

In July 2018 the ACSC became part of the Australian Signals Directorate (ASD), which became a statutory agency. Australian Government cyber security expertise from CERT Australia and the Digital Transformation Agency moved into the ACSC.

These changes are part of the government's national security reform package to enhance the cyber security support and services the government provides to industry, government and the community.

Former ASD and CERT services are now delivered by the ACSC, and we are working on consolidating our online services and advice into one website, This work continues in 2019. Advice on this site remains current; this site will be decommissioned when the migration is completed.

What we do

The ACSC drives cyber resilience across the whole of the economy, including critical infrastructure and systems of national interest, federal, state and local governments, small and medium business, academia, the not-for-profit sector and the Australian community.

It is the hub for private and public sector collaboration and information-sharing, to prevent and combat cyber security threats and to minimise harm to all Australians.

More specifically, the ACSC:

  • responds to cyber security threats and incidents as Australia’s Computer Emergency Response Team (CERT)
  • collaborates with the private and public sector to share information on threats and increase resilience
  • works with governments, industry and the community to increase awareness of cyber security
  • provides information, advice and assistance to all Australians.

The cyber security threat

The internet is where we all conduct our business. Electronic systems and digital information are essential for business and families, with most Australians using the web to bank, pay bills or buy and sell goods and services, and stay connected.

While this digital age presents enormous opportunity for all of us, this increased connectivity comes with greater exposure to cybercriminal activity.

Cyber intrusions on Australian networks are an ever-increasing threat to individuals, businesses and our national security.

How we work

The ACSC began operations in 2014. Since then, and as part of the Independent Intelligence Review in 2017, the Australian Government identified the need to provide enhanced cyber security capabilities and a single point of advice and support on cyber security.

On 1 July 2018, the agency expanded and formally became part of the Australian Signals Directorate (ASD).

The ACSC includes staff from the:

Department of Home Affairs Cyber Security Policy Division staff are collocated with ACSC staff to better inform policy advice for government.

The ACSC is based in Canberra but has offices throughout the country as part of the Joint Cyber Security Centre program.

Frequently-asked questions

Frequently-asked questions about the ACSC and cyber security are answered below.

What is the role of the ACSC?

The ACSC's remit is to drive cyber resilience across the whole of the economy including critical infrastructure and systems of national interest, all levels of government, small and medium business, academia, the not-for-profit sector and the Australian community. The ACSC is part of the Australian Signals Directorate (ASD), bringing together a wider range of government cyber security specialists and capabilities.

When did the ACSC become operational?

The ACSC was opened on Thursday 27 November 2014. The new iteration of the ACSC began in July 2018.

Who has responsibility for the ACSC?

The ACSC is led by the National Cyber Security Adviser, Alastair MacGibbon.

Mr MacGibbon has diverse experience in cyber security, both in the public and private sectors. He was Australia's first eSafety Commissioner, worked as a federal agent for the Australian Federal Police, was a senior director at eBay, and Director of the Centre for Internet Safety at the University of Canberra.

How does the ACSC work with the private sector?

The ACSC builds on the already strong links between government and the private sector, particularly those already established by ACSC agencies.

This includes regional engagement in capital cities across the country. The Joint Cyber Security program will be our key program for engaging with industry. JCSC offices will expand to become the interstate offices of the ACSC, or the ACSC Nodes. This means that, over time, there will be enhanced support and services through the ACSC Nodes for industry, government and the community through greater collaboration and information-sharing.

Canberra-based ACSC staff have moved into ACSC's new building in Brindabella Park, which has been designed to support increased collaboration with the private sector. The new facility is multi-classified, making it more accessible for visitors and staff with lower security classifications.

In August 2018 ACSC launched a new website,, to reflect its new organisation.

Cyber security programs and advice are being migrated to Information and advice on this site remains current.

Reports help the ACSC to develop a better understanding of the threat environment and will assist other organisations who are also at risk.

Cyber security incident reports are also used in aggregate for developing new defensive policies, procedures, techniques and training measures to help prevent future incidents.
