Challenges in Securing Industrial Control Systems Using Future Internet Technologies

Abstract

This chapter explores challenges in securing industrial control systems (ICS) and Supervisory Control And Data Acquisition (SCADA) systems using Future Internet technologies. These technologies include cloud computing, fog computing, Industrial internet of things (IIoT), etc. The need to design specific security solutions for ICS/SCADA networks is explained. A brief overview of cyber vulnerabilities and threats in industrial control networks, cloud, and IoT environments is presented. The security of cloud-based SCADA systems is considered, including benefits and risks of SCADA migration to the cloud, challenges in securing such systems, and migration toward fog computing. Challenges in securing IIoT are addressed, including security risks and operational issues, key principles for securing IIoT, the functional security architecture, and the role of fog computing. Authors point out current standardization activities and trends in the area, and emphasize conclusions and future research directions.
