The Cyber Intelligence Sharing and Protection Act (CISPA) was first introduced in 2011 by Representative Mike Rogers, the chairman of the House Select Committee on Intelligence Committee), and 111 co-sponsors. Although the House of Representatives originally passed the bill on April 25, 2012, it was later rejected by the US Senate.
However, privacy advocates warn that the cybersecurity bill would remove legal liability for firms sharing cybersecurity information with the government.
Under CISPA, private sector firms are encouraged to provide cyber intelligence data to the government, but whether they share such information would remain entirely voluntary.
Shortly after the failed passing of CISPA, the Cybersecurity Information Sharing Act (CISA) was passed as federal law in 2015.
