On March 12, 2015, the Senate Select Committee on Intelligence approved the proposed Cybersecurity Information Sharing Act of 2015 (S. 754), in a nearly unanimous vote.  The proposed legislation authorizes private entities to monitor their own information systems and operate defensive measures for cybersecurity purposes. It also encourages government and private entities to share information about cyber threat indicators and defensive measures.  The bill shields private entities from liability for monitoring their own information systems and for sharing information about cyber threat indicators and defensive measures with the government, assuming they are in compliance with security standards. The bill further aims to increase privacy protections by, among other things, defining a limited scope of information permissibly shared, restricting the methods by which information is shared, and requiring private entities to take proactive steps to remove any personally-identifying information not directly related to the cyber threat prior to sharing.
