President Barack Obama is set to sign an executive order on Friday aimed at encouraging companies to share more information about cybersecurity threats with the government and each other, a response to attacks like that on Sony Entertainment.

The order sets the stage for new private-sector led "information sharing and analysis organizations" (ISAOs) — hubs where companies share cyber threat data with each other and with the Department of Homeland Security.

It is one step in a long effort to make companies as well as privacy and consumer advocates more comfortable with proposed legislation that would offer participating companies liability protection, the White House said.
