SECURING DIGITAL ECONOMIES THROUGH SCADA SYSTEMS: AN ANALYSIS ON AUTHENTICATION AND ACCESS CONTROL

SCADA (Supervisory Control and Data Acquisition) systems are extensively executed in industrial systems to navigate real-time system monitoring, remote access, record, and assembling of data from a centralised unit. SCADA systems are the most essential element in control systems and have a striking influence in industries such as power grids, nuclear power plants and production lines by governing their vital substructure. SCADA has supported the digital economy with a fully automated control that has shown substantial results in lower production costs and increased efficiency in past several years or so. Since more digital field controllers are being implemented around production sites, these formerly unintelligent tools are becoming interconnected and contributing to the digital economy. However, these systems present various vulnerabilities since their frameworks don't enforce core protection metrics. In this paper, we devise certain security measures, for instance, authentication and access control because these control systems are prone to different types of cyber-attacks that can cause major destruction and disruption in production lines. Furthermore, we presented SCADA's future threats and attack hits by conducting an inquiry from several institutes and research areas and explained the facts, predicting to what extent these attacks could rise shortly.
