Fundamentally, the rational for attacking the critical infrastructure centers on three major points.
First is the impact on the national security of the United States by reducing our ability to defend ourselves by limiting the decision space our military maintains in our cyberspace.
Second, the economic strength of the United States could be compro- mised and fundamentally impacted by attacking only 3 of our 16 critical infrastructures. Our electrical grid system creates interdependencies among all 15 remaining critical infrastructures. The economic cost to our nation as a result of a successful attack on this infrastructure would be devastating.
Equally costly to our economy would be successful cyberspace attacks on our transportation and telecommunications infrastructures. Each of these infrastructures also would impact other infrastructures as a result of the nature of interdependencies throughout our nation.
Finally, a successful attack on our infrastructure system would erode public confidence in our nation’s ability to maintain both our national secu- rity and our economic strength.
It is for these reasons that three U.S. presi- dents have directly addressed this potential problem and have issued EOs to organize our nation to defend against the possible attack either physically or in a cyberspace manner.
