Cyberwar Chief Calls for Secure Computer Network

FORT MEADE, Md. — The new commander of the military’s cyberwarfare operations is advocating the creation of a separate, secure computer network to protect civilian government agencies and critical industries like the nation’s power grid against attacks mounted over the Internet.

The officer, Gen. Keith B. Alexander, suggested that such a heavily restricted network would allow the government to impose greater protections for the nation’s vital, official on-line operations. General Alexander labeled the new network “a secure zone, a protected zone.” Others have nicknamed it “dot-secure.”

It would provide to essential networks like those that tie together the banking, aviation, and public utility systems the kind of protection that the military has built around secret military and diplomatic communications networks — although even these are not completely invulnerable.

For years, experts have warned of the risks of Internet attacks on civilian networks. An article published a few months ago by the National Academy of Engineering said that “cyber systems are the ‘weakest link’ in the electricity system,” and that “security must be designed into the system from the start, not glued on as an afterthought.”
