Defense Methodologies of AV Evasion for Access Control and Information Assurance in Industrial Distributed Control Systems and SCADA Systems

Abstract

Distributed control systems (DCS) and Supervisory Control and Data Acquisition (SCADA) systems are extensively used in the areas of critical infrastructure sectors and related environments. These computerized real-time process control systems, over geographically dispersed continuous distribution operations, are increasingly subject to serious damage by cyber means due to their standardization and connectivity to other networks. SCADA and DCS systems generally have little protection from the escalating cyber threats. In order to understand the potential danger and to protect SCADA/DCS systems, in this paper, we present Antivirus Evasion and its Defensive Methodologies for the flow control system monitored by SCADA in the laboratory. We have attempted to demonstrate the vulnerability of SCADA/DCS systems to such threats and have focused on the defensive measures and methods that are need of the day to prevent such attacks in critical infrastructure and industrial sectors.
