Cyber Security

The Australian Signals Directorate’s Australian Cyber Security Centre (ACSC) leads the Australian Government's efforts on cyber security. It brings together capabilities to improve the cyber resilience of the Australian community and help make Australia the most secure place to connect online.

  • exercises and uplift activities to enhance the cyber security resilience of Australian organisations.

ASD cyber security advice is published at our cyber security website,, where you can also report cyber incidents and join ASD’s Cyber Security Partnership Program.

ASD cyber security guidance and programs

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 malicious cyber activity. We provide advice and assistance to all Australians to help make Australia the safest place to connect online.

How we work

ASD’s 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, when ASD became a statutory agency, Australian Government cyber security expertise from Australia’s Computer Emergency Response Team 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.
