  Effectiveness of information security of automated process control systems,
as well as of SCADA, depends on data transmissions protection technologies
applied on transport environments components. This article investigates the
problem of detecting attacks on WSN (wireless sensor networks) of SCADA
systems. As the result of analytical studies the authors developed the detailed
classification of external attacks on sensor networks and brought the detailed
description of attacking impacts on components of SCADA systems in accordance
with selected directions of attacks. Reviewed the methods of intrusion
detection in wireless sensor networks of SCADA systems and functions of WIDS
(wireless intrusion detection systems). Noticed the role of anthropogenic
factors in internal security threats.
