Towards A Taxonomy of Cyber Attacks on Scada System

Abstract

SCADA (SUPERVISORY CONTROL AND DATA ACQUISITION) systems are the software that is used to control the hardware i.e. PLCs, PIDs, etc. and acquires the data from the devices (i.e. SCADA RTU, RTU) into a computer system (i.e. SCADA System). Its function is to handle the plant operations in our plant at remote locations using the control system. This is a modern control system of modern industry where we can read real-time data that means we can exactly monitor the things happening in the field. We emphasize on the differences between SCADA systems and traditional IT systems and on pair of security goals that may secure our computer systems from cyber threats. If the patching goes wrong and it bricks the SCADA system, consequences could be severe like-Contaminated food, explosions, severe death, blackouts, severe injury, etc. Cyber-physical attacks are used on the SCADA system such as switching off the lights of the room where the monitor is present or turning off the camera to perform some attack on a system, hacking the system by cracking a password or destroying firewall. The main intention of SCADA is remote controlling and maintenance.
