Yesterday, before his fifth State of the Union address, President Obama signed a cybersecurity executive order. This is what you need to know about "Improving Critical Infrastructure Cybersecurity."

The Senate worked throughout last year to gain consensus on a cybersecurity bill. The Cybersecurity Act of 2012 sought to establish a National Cybersecurity Council to be chaired by the Secretary of the Department of Homeland Security. The thrust of this particular legislation would have been to put in place a framework for protection of so called “critical infrastructure” - power plants, refineries, chemical production installations and similar facilities.
