Security challenges in SCADA systems over Wireless Sensor and Actuator Networks
Fábio Januário, Carolina Carvalho, Alberto Cardoso, Paulo Sousa Gil · 2016
Supervisory Control And Data Acquisition (SCADA) systems are currently an integrating part of most critical industrial infrastructures, for which security is paramount. Given to their increasing integration with corporate networks, which the industry 4.0 is the most recent driving force, security to cyber attacks can no longer rely on the principle of isolation. In this context, the present paper intends to shed some light on the subject by addressing the problem from each SCADA system components, including its interaction with Wireless Sensor and Actuator Networks (WSANs). The problem of resilience of WSANs is here discussed by appealing to a multi-agent based approach within a distributed middleware framework.
