“The United States is fighting a cyber-war today, and we are losing. It's that simple. As the most wired nation on Earth, we offer the most targets of significance, yet our cyber defenses are woefully lacking. . . . The stakes are enormous. To the extent that the sprawling U.S. economy inhabits a common physical space, it is in our communications networks. If an enemy disrupted our financial and accounting transactions, our equities and bond markets or our retail commerce--or created confusion about the legitimacy of those transactions--chaos would result. Our power grids, air and ground transportation, telecommunications and water filtration systems are in jeopardy as well.”
