A Concise Model to Evaluate Security of SCADA Systems based on Security Standards

Abstract

SCADA systems are essential for the critical infrastructures, such as electric power, oil, and gas production and distribution systems. Hence, incapacitation or destruction of SCADAs would have a debilitating impact on the defence or economic security of organizations and states. In this paper, we study fifteen SCADA cyber security standards and also assess the security of ten widely-used SCADA systems. Our investigation leads to a comprehensive categorized list of security solutions for SCADAs. This list is used to evaluate and compare security of the SCADA systems; also it will be used as model to improve the security of new SCADA systems.
