The cyberwar is escalating

So the US is going to take sanctions against China corporations and individuals caught hacking US systems. 

"The Obama administration is developing a package of unprecedented economic sanctions against Chinese companies and individuals who have benefited from their government’s cybertheft of valuable U.S. trade secrets."

Washington Post  August 30, 2015

It is another step in the escalating cyberwar and it will get worse. IoT (Internet of things) which will explode over the next few years, will be another easy target to hack.
We need to focus on making cyberspace a safe and user-friendly place. So security is the key.
So prevention rather than aggression & repression.
