In recent years governments have been spending millions of dollars trying to stop people using computers to access their secrets. Now Nato has come up with a new initiative to try to prevent efforts to find out about its weapons and intelligence. The Cyber Defence Management Authority was given the green light at the latest meeting of the organisation this month in Romania. The body means Nato is now focusing its efforts on protecting the computer capabilities of its member countries - not just its own internal systems. Stephen Cole reports for Al Jazeera.
