Cyber Security

The Australian Cyber Security Centre (ACSC) within ASD leads the Australian Government's efforts 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 help make Australia the most secure place to connect online.

ASD cyber security advice is published at our Australian Cyber Security Centre (ACSC) website, You can also report cyber incidents and sign up for cyber security alerts.

The cyber security threat

The internet is a critical part of 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 also brings exposure to cybercriminal activity. We provide advice and assistance to all Australians to help make Australia the safest place to connect online.

What we do

The ACSC is a hub for private and public sector collaboration and information-sharing on cyber security, to prevent and combat threats and minimise harm to Australians. We provide advice and assistance across the whole economy, including critical infrastructure and systems of national interest, federal, state and local governments, small and medium businesses, academia, not-for-profit organisations and the Australian community.

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 cyber security information, advice and assistance to all Australians.

How we work

The ACSC began operations in 2014 as a collaboration between government agencies. 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 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 includes staff from the:

Department of Home Affairs Cyber Security Policy Division staff are collocated with ACSC staff to collaborate in providing policy advice for government.

The ACSC is based in Canberra but has offices across the country through the Joint Cyber Security Centre program.
