With cyber-security legislation stalled in Congress, President Barack Obama issued an executive order that could have far-reaching effects on businesses of all types.

The order expands efforts to share information, both classified and un-classified, between companies and the government on imminent threats to critical infrastructure from online attacks. It also calls for standardized cyber-security practices. The National Institute of Standards and Technology will develop voluntary standards and practices for reducing cyber-threats to infrastructure, such as nuclear power plants and the electrical power grid.
