Supervisory control and data acquisition (SCADA) networks contain computers and applications that perform
key functions in providing essential services and commodities (e.g., electricity, natural gas, gasoline, water, waste
treatment, transportation) to all Americans. As such, they are part of the nation’s critical infrastructure and
require protection from a variety of threats that exist in cyber space today. By allowing the collection and analysis
of data and control of equipment such as pumps and valves from remote locations, SCADA networks provide
great efficiency and are widely used. However, they also present a security risk.
