Reference Model for Control and Automation Systems in Electrical Power (October 2005)

Modern infrastructure automation systems are threatened by cyber attack. Their higher visibility in recent years and the increasing use of modern information technology (IT) components contribute to increased security risk. A means of analyzing these infrastructure automation systems is needed to help understand and study the many system relationships that affect the overall security of the system. Modeling these systems is a very cost effective means of addressing the problem of security from an overall system view.

The model presented in the document below provides a structured, cost effective approach to address technical security in process control systems in a way that is consistent with the operation and mission of that system.
