In plain terms. The Cybersecurity Information Sharing Act of 2015 (the core of the Cybersecurity Act of 2015) authorizes the voluntary exchange of cyber threat indicators and defensive measures between the private sector and the federal government, with liability protections and privacy safeguards for participants. It established the principal legal channel for U.S. public-private cyber threat sharing.
