Hardening U.S. critical infrastructure sectors against network attacks and vulnerabilities is a national security priority, but a comprehensive plan of action remains elusive. Key to meeting this challenge is forging a national consensus on roles and missions within government and between government and the private sector, wherein most critical infrastructure resides. This session will assess risk formulas for countering network threats to critical infrastructure, the significance of cyber vulnerabilities to national security, importance of national intelligence in prioritizing threats, roles and missions within government, and the state of governmentâprivate sector cooperation.
