WASHINGTON (Reuters) - The cyber attack on Sony Pictures underscores the need for U.S. businesses and government to cooperate on cyber threats and for chief executives to assess their companies' cybersecurity, Homeland Security Secretary Jeh Johnson said on Friday. "The Department of Homeland Security and other federal agencies are here to help. We seek to raise the level of cybersecurity in both the private sector and civilian government, and provide timely information to protect all our systems against cyber threats," he said in a statement.
