Our nation can be threatened not only by physical attacks on terra firma, but also in Cyberspace. Indeed, Cyber attacks could threaten all sorts of mission critical systems.
For this reason, aides to Senator Jay Rockefeller reportedly have been working recently on a revised draft Senate bill that would give the President broad powers in the event of a Cybersecurity emergency, and that apparently would go so far as allowing the President to temporarily seize control over computer networks in the private sector.
This power is akin to the power President Bush exerted when he grounded commercial aircraft in the wake of the September 11, 2001 World Trade Center and Pentagon attacks, according to a reported Senate source.
