History

Historical Context

Ramzi Yousef’s 1993 World Trade Center van bomb killed six and injured more than a thousand, exposing infrastructure flaws. The 2001 September 11 attacks spurred the 2002 Homeland Security Act, creating the Department of Homeland Security. Today, DHS and the Western Virginia Water Authority are hardening SCADA systems and running vulnerability assessments to guard water and transit networks against small-cell terrorism.
