Sharing information on the cyber landscape is a necessary and efficient way to benefit from mutual exposure to cyber threats and boost collective defensive capacity.

The US has been pursuing cyber information sharing since the late 1990s, when the federal government directed the creation of public–private partnerships for critical infrastructure protection. The now decades-long development of a variety of information sharing models in the US provide case studies and lessons for the Australian cybersecurity community as it pursues deeper information sharing mechanisms.

This paper draws on the examples, issues and recommendations discussed in the MITRE Corporation report Building a national cyber information sharing ecosystem, by Bruce J Bakis and Edward D Wang. This paper offers recommendations for the development of Australia’s national cyber information sharing system.
