NATO members at a December meeting took note of lingering cybersecurity thoughts, though Julianne Smith, an expert on NATO and U.S. foreign policy at Chatham House, said the alliance has more work to do on the emerging threat.
"NATO's summit this September, as it stands now, looks a little thin on bold new ideas," she said in a report published Thursday. "If the alliance is looking for a way to inject more innovation, it should redouble its efforts between now and September to put forward the most comprehensive agenda possible on cybersecurity."
U.S. Army Maj. Gen. John Davis, a policy adviser for the military, said last year cybersecurity was fast becoming a top national security concern.
Countries ranging from Iran, China and the United States have expressed concern about cyberthreats.
The U.S. House Homeland Security Committee backed legislation Wednesday that would increase defense capabilities against cyberthreats. Rep. Pat Meehan, R-Pa., chairman of a subcommittee on counter-terrorism, said in a statement the "federal government's response to the cyber threat has so far been haphazard."
