Cyber security

The Australian Cyber Security Centre (ACSC) 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.

The ACSC's website replaces a number of government cyber security websites and services. ASD cyber security programs and advice have been migrated to

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 and social lives. Electronic systems and digital information are essential for business and families, with most Australians using the web to bank, pay bills, buy and sell goods and services, and stay connected.

While this digital age presents enormous opportunity , connectivity comes with exposure to cybercriminal activity.

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 ACSC expanded and formally became part of the Australian Signals Directorate.

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.
