The trends of supervisory control and data acquisition security challenges in heterogeneous networks

Abstract

<p>Supervisory control and data acquisition (SCADA) has an important role in communication between devices in strategic industries such as power plant grid/network. Besides, the SCADA system is now open to any external heterogeneous networks to facilitate monitoring of industrial equipment, but this causes a new vulnerability in the SCADA network system. Any disruption on the SCADA system will give rise to a dangerous impact on industrial devices. Therefore, deep research and development of reliable intrusion detection system (IDS) for SCADA system/network is required. Via a thorough literature review, this paper firstly discusses current security issues of SCADA system and look closely benchmark dataset and SCADA security holes, followed by SCADA traffic anomaly recognition using artificial intelligence techniques and visual traffic monitoring system. Then, touches on the encryption technique suitable for the SCADA network. In the end, this paper gives the trend of SCADA IDS in the future and provides a proposed model to generate a reliable IDS, this model is proposed based on the investigation of previous researches. This paper focuses on SCADA systems that use IEC 60870-5-104 (IEC 104) protocol and distributed network protocol version 3 (DNP3) protocol as many SCADA systems use these two protocols.</p>

SCADA and Distributed Control System of a Chemical Products Dispatch Process

“…Referring to a distributed control system implies the generation of relevant data, which goes beyond operational aspects, becoming linked to very useful and important information systems at a strategic level in an organization [13]. With the purpose of supervising, monitoring and acquiring data for decision-making on aspects related to the operation or operation of an industrial process, SCADA systems (Supervisory Control and Data Acquisition) are used [14][15][16][17]. The application of SCADA systems is diverse, however among the processes that use it the most are electricity generation, natural gas, mining deposits, thermal systems, oil pipelines and chemical products dispatch [18][19][20].…”
