This fact sheet discusses current measures taken by the Dept. of Homeland Security (DHS) to prevent future cyber attacks and intrusion attempts. "The Federal Government is continually increasing capabilities to address cyber risk associated with critical networks and information systems. On January 8, 2008, President Bush approved National Security Presidential Directive 54/Homeland Security Presidential Directive 23, which formalized a series of continuous efforts designed to further safeguard Federal Government systems and reduce potential vulnerabilities, protect against intrusion attempts, and better anticipate future threats. While efforts to protect our Federal network systems from cyber attacks remain a collaborative, government-wide effort, the DHS has the lead responsibility for assuring the security, resiliency and reliability of the Nation's Information Technology (IT) and communications infrastructure."
