Information Security and Critical Infrastructure Protection
More than 1.5 billion people in over 200 countries now spend a great deal of time in cyberspace. We work and shop there. We are educated and entertained there. We socialize with family, friends, and strangers in cyberspace. We are paid and we pay others through this medium. Tens of millions of commercial enterprises, and local, state, national, and international agencies do their business there. It has become a critical infrastructure in its own right, and it is embedded in almost all other critical infrastructures.
