On Tuesday, October 27, the U.S. Senate approved legislation, strongly supported by business groups, that would facilitate information sharing between government and industry and provide liability protection to companies that participate. The Cybersecurity Information Sharing Act of 2015 (CISA) passed the Senate by a bipartisan vote of 74-21, setting the stage for a House-Senate conference committee that will work to resolve differences between CISA and similar legislation passed by the House in April and to prepare a final bill to be considered by both chambers of Congress for potential enactment into law.
