SCADA Security

SCADA Security: "Because of the limited attention paid to security, both DCS and SCADA systems are perceived as being largely unsecured and vulnerable to attack, as noted by a Government Accountability Office report last year. The report included many examples of attacks on control systems including:

A cybersecurity breach in 1994 of the Salt River Project, a major water and electricity provider in Tempe, Ariz.

SQL Slammer worm infection of the Davis-Besse nuclear power plant in Oak Harbor, Ohio, in 2003. The plant's process computer failed, requiring more than six hours for recovery. Control-system traffic was also blocked on five other utilities. "
