Taxonomy of SCADA systems security testbeds
Considerable research has focused on developing simulation environments to study the effects of cyber–attacks on supervisory control and data acquisition (SCADA) systems although a methodology to develop a SCADA security testbed is not yet available. This paper attempts to address the issue by presenting a reference model taken from the literature and classifying specific contributions on the development of SCADA security testbed according to the reference model. Specific techniques and experiments used to recreate cyber–attacks on the de facto standard communication protocol Modbus are also presented. This paper also explores the possibility of integrating specific simulation models into a SCADA security testbed to assess the impact of cyber–attacks on the physical system.
