Cybersecurity: Threats Impacting the Nation
In this congressional testimony, it is argued that since nearly every aspect of US society increasingly depends upon information technology systems and networks, the vulnerability to cyber-based threats has also increased. Pervasive and sustained cyber attacks against the United States could have a potentially devastating impact on federal and nonfederal systems, disrupting the operations of governments and businesses and the lives of private individuals. This statement describes (1) cyber threats facing US systems, (2) vulnerabilities present in federal information systems and systems supporting critical infrastructure, and (3) reported cyber incidents and their impacts.
