Water Sector Coordinating Council, Cyber Security Working Group, Roadmap to Secure Control Systems in the Water Sector (Mar. 2008) (full-text).
Today's industrial control systems (ICS) environments are complex assemblages of technology, processes, and people that work together to successfully carry out the missions and business functions of an organization. These systems have improved water and wastewater service and increased reliability in those infrastructures. As ICS have become more affordable and easier to use, most utilities have chosen to adopt them for process monitoring and/or process control. This reliance on ICS has left the water sector and other dependent critical infrastructures vulnerable to targeted cyber attack or accidental cyber events.
