Cybersecurity is a matter of National, economic, and societal importance. Present-day attacks on the Nation's computer systems do not simply damage an isolated machine or disrupt a single enterprise system, but current attacks target infrastructure that is integral to the economy, National defense, and daily life. Computer networks have joined food, water, transportation, and energy as critical resources for the functioning of the National economy. When one of these key cyber infrastructure systems is attacked, the same consequences exist as those for a natural disaster or terrorist attack.
