TISN

​​​​​Welcome to the TISN website​

Critical infrastructure delivers essential services such as food, water, healthcare, electricity, communications, transportation and banking. Without these services, Australia's social cohesion, economic prosperity and public safety are threatened. The resilience of our critical infrastructure is therefore integral to a strong economy and a vibrant business sector. It is also vital to the resilience of our communities to disasters.

The Trusted Information Sharing Network (TISN) for Critical Infrastructure Resilience was established by the Australian Government in 2003. It is Australia's primary national engagement mechanism for business-government information sharing and resilience building initiatives on critical infrastructure resilience. The TISN provides a secure environment for critical infrastructure owners and operators across eight sector groups to regularly share information and cooperate within and across sectors to address security and business continuity challenges.

The work of the TISN is also complemented by a range of business-government engagement mechanisms on broader national security policy issues.

Protecting Australia’s economy, national security and sovereignty is the Government’s top priority. The Australian Government is currently aware of, and responding to, a sustained targeting of Australian governments and companies by a sophisticated state-based actor. 

On 19 June 2020, the Australian Cyber Security Centre and the Critical Infrastructure Centre in the Department of Home Affairs released an advisory to businesses about how to protect themselves against a sophisticated cyber compromise following widespread targeting of Australian networks by a sophisticated state-based actor.

For details, see the Advisory 2020-008: Copy-paste compromises – tactics, techniques and procedures used to target multiple Australian networks [2MB PDF].​​
