For years, the private sector has been on the front line battling devastating cyber attacks from criminals, activists in nation-states such as Iran, China, Russia, and North Korea. Any cyber threat-sharing legislation produced by Congress should enhance existing capabilities and relationships while establishing procedures to safeguard personal privacy. The cyber breach of health insurance giant Anthem exposed the personal information of up to 80 million Americans, approximately 1 in every 4 Americans, demonstrating that the quantity and sophistication of these attacks is only increasing. The director of national intelligence, James Clapper, underscored this fact, stating that cyber attacks against the U.S. are increasing in frequency, scale, sophistication, and severity of impact and that the methods of attack and the systems targeted and the victims are also expanding in diversity and intensity on a daily basis.
