Dive Insight:

The new agreement signed last week between the U.S. and China focuses on cyberespionage, but Rogers said the two countries need to expand that to address theft of intellectual property as well.

"The greatest amount of activity is still criminal-based, but when I look at [it] from a national security perspective I would argue at the moment the nation-state represents the greater national security challenge," Rogers said.

Rogers supports a multilateral agreement on "norms" in the cyber arena that would curtail cyberespionage as well as theft of intellectual property.
