The national security of the United States, our economic prosperity, and the daily functioning of our government are dependent on a dynamic public and private information infrastructure, which includes telecommunications, computer networks and systems, and the information residing within. This critical infrastructure is severely threatened. This cyber domain is exponentially expanding our ability to create and share knowledge, but it is also enabling those who would steal, corrupt, harm or destroy the public and private assets vital to our national interests. The recent intrusions reported by Google are a stark reminder of the importance of these cyber assets, and a wake-up call to those who have not taken this problem seriously. Companies who promptly report cyber intrusions to government authorities greatly help us to understand and address the range of cyber threats that face us all. I am here today to stress that, acting independently, neither the US Government nor the private sector can fully control or protect the country’s information infrastructure. Yet, with increased national attention and investment in cyber security initiatives, I am confident the United States can implement measures to mitigate this negative situation.
