Cyber security risk assessment method for SCADA system

Abstract

ABSTRACT Nowadays SCADA is very important for controlling large systems like pipeline, industrial manufacture, power plant as well as in the communication system. For controlling a large system by making human machine interface (HMI) its needs to connect over a network like WAN or internet. So the SCADA system involves an issue called cyber security. Cyber security risk assessment for digital instrumentation and control system has become more crucial in the development of a new system and operation of the existing system. The cyber attack on the SCADA system could compromise the system as well as damage the components and impact the financial on the process or invoke an unwanted command. In this paper, we propose a risk assessment method which includes system analysis, attack modeling and analysis, penetrate the system. This will show the impact on the system. At long last countermeasures are distinguished for the development of digital security.
