On June 15, the Department of Homeland Security, jointly with the Department of Justice, issued its final procedures and final guidelines for cybersecurity threat information sharing, which were required by the Cybersecurity Act of 2015.  DHS also released updated guidance for non-federal entities sharing information with the government under the Act.  The procedures and guidelines relate to Title I of the Act, entitled the Cybersecurity Information Sharing Act of 2015 (CISA), which provides processes and protections for sharing cybersecurity threat information between government and private sector entities.  DHS had issued interim versions of the procedures and guidelines, along with two other guidance documents in February 2016.  It was required by CISA to issue the final versions of the procedures and guidelines, and also opted to release updated guidance based on feedback from industry.
