The Senate has defeated a revised version of the Obama administration-backed Cybersecurity Act, failing to reach the 60 votes needed for passage. The measure would have directed the Department of Homeland Security to conduct cybersecurity risk assessments of critical infrastructure and carry out responses. The bill had been updated to reflect a number of privacy concerns after President Obama threatened a veto earlier this year. The new provisions called for annual disclosures of the information collected by government agencies and would grant U.S. citizens to sue the government in the case of violations.
