Trusted Information Sharing Network (TISN) sector groups enable critical infrastructure owners and operators to share information about threats and vulnerabilities. They also allow members to collaborate to reduce risks and improve resilience.
The Australian Government supports each sector group with secretariat support and subject matter expertise. You may be eligible to join one or multiple TISN sector groups if your organisation falls under the sector definitions in section 5 of the
Security of Critical Infrastructure Act. For example, you may own a transport asset that is connected to the food and grocery sector, so you may be able to join both the Food and Grocery and the Transport sector groups.
An industry chair or co-chairs, together with a government co-chair, lead each sector group. The sector group’s co-chairs are responsible for providing leadership to their sector group and distributing information, including communications from the Critical Infrastructure Advisory Council (CIAC).
Some sector groups include internal sub-groups, which enables targeted engagement for members in specific areas of the sector.
For example, the Transport Sector Group includes sub-groups for aviation, air cargo, maritime and land transport.
