From the opening statement of Daniel Lungren: "We convene today to focus on the protection of control systems at our Nation's critical infrastructure. Control systems are utilized in a wide variety of industries- such as electrical generation and distribution, oil and gas systems, traffic signals and other transportation supervision, water management (including dams), and manufacturing industries. These control systems are commonly referred to as SCADA systems. These computer terminals have the ability to give supervisory control to a central user over separate and often disparate functions or processes. Further, SCADA systems collect information from remote locations and coalesce it into one location. Now what does this actually mean? Simply put, a manufacturing facility or any of the aforementioned facilities incorporate many different processes and functions. To safely, securely, and efficiently run the facility, companies must be able to monitor and adjust these processes simultaneously. Before SCADA systems, workers would be placed throughout a facility and manually monitor and adjust the various systems. SCADA systems bring monitoring and control of these functions into one centralized location, making it easier and more efficient to run these processes. At the same time, these systems present serious security challenges. Because these terminals control crucial systems within our critical infrastructure and are often connected to networks and can be remotely accessed, they present an attractive means for those wishing to cause harm and confusion." Statements, letters, and materials submitted for the record include those of the following: K.P. Ananth, Alan Paller, Donald ''Andy'' Purdy, William Rush, Larry Todd, and Sam Varnado.
